The Second Avenue Subway (internally referred to as the IND Second Avenue Line by the MTA and abbreviated to SAS) is a New York City Subway line that runs under Second Avenue on the East Side of Manhattan. The first phase of this new line, with three new stations on Manhattan's Upper East Side, opened on January 1, 2017. The full Second Avenue Line, if and when it is funded, will be built in three more phases to eventually connect Harlem–125th Street in Harlem to Hanover Square in Lower Manhattan. The proposed full line would be 8.5 miles (13.7 km) and 16 stations long, serve a projected daily ridership of 560,000, and cost more than $17 billion.
The line was originally proposed in 1919 as part of a massive expansion of what would become the Independent Subway System (IND). In anticipation of the Second Avenue Subway being built to replace them, parallel elevated lines along Second Avenue and Third Avenue were demolished in 1942 and 1955, respectively, despite several factors causing plans for the Second Avenue Subway to be cancelled. Construction on the line finally began in 1972 as part of the Program for Action, but was halted in 1975 because of the city's fiscal crisis, leaving only a few short segments of tunnels completed. Work on the line restarted in April 2007 following the development of a financially secure construction plan. The first phase of the line, consisting of the 96th Street, 86th Street, and 72nd Street stations and two miles (3.2 km) of tunnel, cost $4.45 billion. A 1.5-mile (2.4 km), $6 billion second phase from 96th to 125th Streets is in planning and is expected to open by 2027–2029.
Phase 1 is served by the Q train at all times and limited rush-hour N and R trains. Phase 2 will extend the line's northern terminus from 96th Street to Harlem–125th Street, and both the Q and limited N services will be extended to 125th Street. Phase 3 will extend the line south from 72nd Street to Houston Street in Manhattan's Lower East Side; upon completion, a new T train will serve the entire line from Harlem to Houston Street. Phase 4 will again extend the line south from Houston Street to Hanover Square, at which point the T would provide service to the entire line. The T will be colored turquoise since it will use the Second Avenue Line through Midtown Manhattan.

Phase 1 of the Second Avenue Line opened in January 2017 and runs under Manhattan's Second Avenue from 65th Street to 105th Street, with stations at 72nd Street, 86th Street, and 96th Street. It is double-tracked along its entire length, with tracks in parallel tubes bored by tunnel boring machines, and central island platforms at all stations. North of 96th Street, both tracks continue as storage tracks until they end at 105th Street.
As part of Phase 1, the Second Avenue Subway connects to the BMT Broadway Line using an existing connection via the 63rd Street Line. The Q, as well as and limited rush-hour N and R, operate northward from 57th Street–Seventh Avenue on the Broadway Line, curving east under Central Park on the 63rd Street Line. The Broadway trains then stop at Lexington Avenue–63rd Street with a cross-platform interchange to the F train before merging with the Second Avenue Line near 65th Street; this connection is also double-tracked. The northbound 63rd Street Connector track dips below the level of Phase 3's planned tunnels, providing for a future flying junction between the connector and the rest of the Second Avenue Line.
The long-term plans for the Second Avenue Subway involve digging 8.5 miles (13.7 km) of new tunnels north to 125th Street in Harlem and south to Hanover Square in the Financial District of Lower Manhattan. The entire line would also be double-tracked, except for a tentatively four-tracked segment between 21st and 9th Streets, including the 14th Street station, with the outer two tracks used to store trains. After Phase 4 is completed, the residents of Spanish Harlem and the Upper East Side will have mass transit service down both Second Avenue and Broadway to the Financial District (the latter via transfer to Broadway local trains), as well as across the Manhattan Bridge to Brooklyn via the Q train.:5B·19
An additional two-track connection is planned at around 63rd Street that will connect the Lower Manhattan-bound tracks on the Second Avenue Line with the Queens-bound tracks on the IND 63rd Street Line, using existing bellmouths at 63rd Street and First Avenue. Current plans do not call for it to be used by regular service; instead, it would be used for moving out-of-service trains.:7 The connection would allow for trains to run from the Financial District to Queens if the capacity of the IND Queens Boulevard Line were increased, or if the Queens Bypass were built. Service from Queens via the 63rd Street Tunnel would allow for the full capacity of the line south of 63rd Street to be used. The whole line will be designed to accommodate 30 trains per hour, with the exception of the terminal at Hanover Square, which will only be able to handle 26 trains per hour (TPH). The portion north of 63rd Street is planned to have 14 TPH on the Q and 14 TPH on the T, for a combined 28 trains per hour on both routes. South of there, only 14 TPH on the T are planned, although 12 additional TPH could be provided in the future via the 63rd Street Tunnel.:5B·20 The 2004 plans for the Second Avenue Subway include the construction of short track segments to allow a future extension north under Second Avenue past 125th Street to the Bronx, as well as an extension south to Brooklyn.:11, 12
In order to store the 330 additional subway cars needed for the operation of the line, storage tracks would be built between 21st Street and 9th Street along the main alignment. The 36th–38th Street Yard in Sunset Park, Brooklyn, would also be reconfigured.:26
The Second Avenue Subway is chained as "S". The track map in the 2004 FEIS showed that all stations, except for 125th Street, would have two tracks and one island platform. 72nd Street and 125th Street were conceived as three-track, two-platform stations. 72nd Street was eventually scaled down to a two-track, center island platform station in order to reduce costs, A three-tracked 72nd Street station would have allowed trains from the Broadway Line to short-turn (reverse) without interfering with mainline service on Second Avenue, as well as provided additional operational flexibility for construction work and non-revenue moves.:20 In July 2018, the 125th Street station was also scaled down to a two-track, one-platform station because the MTA had ascertained that two-tracked terminals would be sufficient to handle train capacities, and that building a third track would have caused unnecessary impacts to surrounding buildings.:13
After World War I, the New York City Subway experienced a surge in ridership. By 1920, 1.3 billion annual passengers were riding the subway, compared to 523 million annual riders just seven years before the war. In 1919, the New York Public Service Commission launched a study at the behest of engineer Daniel L. Turner to determine what improvements were needed in the city's public transport system. Turner's final paper, titled Proposed Comprehensive Rapid Transit System, was a massive plan calling for new routes under almost every north-south Manhattan avenue, extensions to lines in Brooklyn and Queens, and several crossings of the Narrows to Staten Island.:22–25 Among the plans were was a massive trunk line under Second Avenue consisting of at least six tracks and numerous branches throughout Brooklyn, Queens, and the Bronx; in turn, the Second and Third Avenue elevated lines were to be knocked down to make room for the 6-track subway.:203 The paper was revised in January 1927.
On September 15, 1929, the Board of Transportation of the City of New York (BOT) tentatively approved the expansion, which included a Second Avenue Line with a projected construction cost of $98,900,000 (equivalent to $1,397,000,000 in 2017), not counting land acquisition. In the north, several spur lines in the Bronx would merge into a four-track trunk line, crossing the Harlem River south to 125th Street. There would six tracks from 125th Street to a link with the IND Sixth Avenue Line at 61st Street, then four tracks from 61st Street to Chambers Street, and finally two tracks from Chambers Street to Pine Street. But the Great Depression began that year and the soaring costs of the expansion became unmanageable. Construction on the first phase of the IND was already behind schedule, and the city and state were no longer able to provide funding. By 1930, the line was scaled down, with the line from 125th to Houston Streets to be complete by 1940, as well as a spur along 34th Street to be done by 1948. This scaled-down plan was postponed in 1931. By 1932, the Board of Transportation had modified the plan to further reduce costs, omitting a branch in the Bronx, and truncating the line's southern terminus to the Nassau Street Loop.:204–205
Further revision of the plan and more studies followed. By 1939, construction had been postponed indefinitely, with only a short length being completed above the Second Avenue station. The Second Avenue Line was relegated to "proposed" status, and was number 14 on the Board of Transportation's list of important transportation projects. The line was cut to two tracks with single northern branch through Throggs Neck, Bronx, a connection to the BMT Broadway Line in Manhattan, and a continuation south onto the IND Fulton Street Line in Brooklyn via that line's Court Street station.:205 The subway's projected cost went up to US$249 million (equivalent to $4,143,000,000 in 2017). The United States' entry into World War II in 1941 halted all but the most urgent public works projects, delaying the Second Avenue Line once again.
As part of the unification of the three subway companies that comprised the New York City Subway in 1940, elevated lines were being shut down all over the city and replaced by subways.:205–206 The northern half of the Second Avenue Elevated, serving the Upper East Side and East Harlem, closed on June 11, 1940; the southern half, running through Lower Manhattan, East Midtown and across the Queensborough Bridge to Queens, closed on June 13, 1942. The demolition of the Second Avenue elevated caused overcrowding on the Astoria and Flushing Lines in Queens, which no longer had direct service to Manhattan's far East Side.:208 Because of the elevated line's closure, as well as a corresponding increase in the East Side's population, the need for a Second Avenue subway increased.
In 1944, BOT superintendent Philip E. Pheifer put forth a proposal for Second Avenue Subway services, which would branch extensively off to B Division.:209–210 The subway was originally to be opened by 1951, but by 1945, plans for the Second Avenue Subway were again revised.:210–211 Another plan was put forth in 1947 by Colonel Sidney H. Bingham, a city planner and former Interborough Rapid Transit Company (IRT) engineer. O'Dwyer and Gross believed that construction of a Second Avenue subway line would be vital to both increasing capacity on existing lines and allowing new branch lines to be built.:209 Bingham's proposal involved more branch lines and track connections than did Phiefer's, and similar to the 1960s and 1990s phased proposals, was to be built in sections.:209 However, by the next year, New York City was short $145 million that was needed for a $800 million program for rehabilitation and proposed capital improvements. The City petitioned the New York State Legislature to exceed its $655 million debt ceiling so that the city could spend $500 million on subway construction, but this request was denied.
The BOT then ordered ten new prototype subway cars made of stainless steel from the Budd Company. These R11 cars, so called because of their contract number, were delivered in 1949 and specifically intended for the Second Avenue Subway. They cost US$100,000 (equivalent to $1,000,000 in 2017) each; the train became known as the "million dollar train". The cars featured porthole style round windows and a new public address system. Reflecting public health concerns of the day, especially regarding polio, the R11 cars were equipped with electrostatic air filters and ultraviolet lamps in their ventilation systems to kill germs.
In 1949, Queens and Lower Manhattan residents complained that the Second Avenue Subway would not create better transit options for them. A year later, a revised plan was devised that involved connections from Queens. New York voters approved a bond measure for its construction in 1951, and the city was barely able to raise the requisite $559 million for the construction effort. However, the onset of the Korean War caused soaring prices for construction materials and saw the beginning of massive inflation. Money from the 1951 bond measure was diverted to buy new cars, lengthen platforms, and maintain other parts of the aging New York City Subway system. Out of a half-billion-dollar bond measure, only $112 million (equivalent to $1,056,000,000 in 2017), or 22% of the original amount, went toward the Second Avenue Subway. By then, construction was due to start by either 1952 or 1957, with estimated completion by 1958 at the earliest.
The Third Avenue Elevated, the only other elevated line in the area, closed on May 13, 1955, and was demolished in 1956. The Lexington Avenue Line was now the only subway transportation option on the East Side, leading to overcrowding. By 1957, the 1951 bond issue had been almost entirely used for other projects,:216 and the New York Times despaired of the line's ever being built. "It certainly will cost more than $500,000,000 and will require a new bond issue," wrote one reporter.
As the early 1960s progressed, the East Side experienced an increase in development, and the Lexington Avenue Line became overcrowded. In 1962, construction began on a connection between the Manhattan and Williamsburg Bridges and the Sixth Avenue Line. This segment, the Chrystie Street Connection, was first proposed in the 1947 plan as the southern end of the Second Avenue line, which would feed into the two bridges. When opened in November 1967, the connection included the new Grand Street station on the Sixth Avenue Line (another station, 57th Street, opened in July 1968), and introduced the most significant service changes ever carried out in the subway's history.:216–217 Grand Street, located under Chrystie Street (the southern end of Second Avenue) was designed to include cross-platform transfers between the Sixth Avenue and Second Avenue Lines.
Separately, in 1967, voters approved a $2.5 billion (worth about $18,348,000,000 in current dollars) Transportation Bond Issue, which provided over $600 million (worth $4,404,000,000 today) for New York City projects, including for a 1968 Program for Action. The City secured a $25 million Urban Mass Transportation Act (UMTA) grant for initial construction.:219 The Program for Action proposed a Second Avenue line to be built in two phases: a first phase north of 34th Street and a second phase south of there. The Second Avenue project, for a line from 34th Street to the Bronx, was given top priority. However, the line's planned stops in Manhattan, spaced farther apart than those on existing subway lines, proved controversial;:37 the Second Avenue line was criticized as a "rich man's express, circumventing the Lower East Side with its complexes of high-rise low- and middle-income housing and slums in favor of a silk stocking route.”:218 In response to protests, the MTA added stations at 72nd Street and 96th Street The MTA issued a plan for a spur line, called the "cuphandle", to serve the heart of the Lower East Side. Branching off from the IND Sixth Avenue Line near the Second Avenue station, the spur would run east on Houston Street, turn north on Avenue C, and turn west on 14th Street, connecting to the BMT Canarsie Line.
A combination of Federal and State funding was obtained for the project. In March 1972, the entire cost of the section between 34th Street and 126th Street, according to the project's Draft Environmental Study, was estimated to be $381 million.:1 In June 1972, it was announced that the UMTA would grant $25 million for the construction of this section of the line. The MTA had requested $254 million in federal funds for the northern part of the line. Preliminary estimates of the cost of the southern portion of the line came to $450 million.
Construction on a tunnel segment between 99th and 105th Streets began in October 1972. A second segment between 110th and 120th Street in East Harlem started construction in March 1973. On October 25, 1973, the line's Chinatown segment commenced construction at Canal Street under the foot of the Manhattan Bridge between Canal and Division Streets. A fourth segment started construction on July 25, 1974, between Second and Ninth Streets in the East Village. In total, construction on the Second Avenue Line during the 1970s spanned over 27 blocks.
The city soon experienced its most dire fiscal crisis yet, due to the stagnant economy of the early 1970s, combined with the massive outflow of city residents to the suburbs. The system was already in decline; the subway had seen a 40% decrease in ridership since 1947, and a $200 million subsidy for the MTA as well as a 1952 fare increase had not been enough to pay for basic upkeep for the subway system, let alone fund massive expansion projects like the Second Avenue Subway.:52 When plans were finalized in 1971, the subway had been proposed for completion by 1980,:38 but two years later, its completion date was forecast as 2000.:52 In October 1974, the MTA chairman, David Yunich, announced that the completion of the line north of 42nd Street was pushed back to 1983 and the portion to the south in 1988. On December 13, 1974, New York City mayor Abraham Beame proposed a six-year transit construction program that would reallocate $5.1 billion of funding from the Second Avenue Line to complete new lines in Queens and to modernize the existing infrastructure, which was rapidly deteriorating and in dire need of repair. Beame issued a stop-work order for the line in September 1975, whereupon construction of the section between Second and Ninth Streets was halted, and no other funding was allocated to the line's construction. Besides the Chrystie Street Connection, only three sections of tunnel had been completed; these tunnels were sealed.
By 1978, when the New York City Subway was at its lowest point in its existence, State Comptroller Arthur Levitt stated that there were no plans to finish the line. During the 1980s, plans for the Second Avenue line stagnated. Construction on the 63rd Street Lines continued; the IND portion of the line opened in 1989 and extended to 21st Street–Queensbridge in Long Island City, Queens, but it did not include a connection to the Second Avenue line. Of this failure to complete construction, Gene Russianoff, an advocate for subway riders since 1981, stated: "It's the most famous thing that's never been built in New York City, so everyone is skeptical and rightly so. It's much-promised and never delivered."
With the city's economic and budgetary recovery in the 1990s, there was a revival of efforts to complete construction of the SAS. Rising ridership on the IRT Lexington Avenue Line, the only subway trunk line east of Central Park, demonstrated the need for the Second Avenue Line, as capacity and safety concerns rose. The four-track IRT Lexington Avenue Line, the lone rapid transit option in the Upper East Side and East Harlem since the 1955 closure of the Third Avenue elevated, is the most crowded subway line in the country. The line saw an average of 1.3 million daily riders in 2015; this is more than the daily ridership of the second-busiest subway system in the U.S., the Washington Metro, as well as more than the combined daily riderships of San Francisco's and Boston's transit systems. Local bus routes are just as crowded during various times of the day, with the parallel M15 local and M15 Select Bus Service routes seeing 46,000 passengers per weekday in 2016, translating to 14.5 million passengers that year.
In 1991, then-New York Governor Mario Cuomo allocated $22 million to renew planning and design efforts for the Second Avenue line, but two years later, the MTA, facing budget cuts, removed these funds from its capital budget. In 1995, the MTA began its Manhattan East Side Alternatives (MESA) study, both a MIS and a DEIS, seeking ways to alleviate overcrowding on the Lexington Avenue Line and improve mobility on Manhattan's East Side. The study analyzed several alternatives, such as improvements to the Lexington Avenue Line to increase capacity, enhanced bus service with dedicated lanes, and light rail or ferry service on the East Side.:7–8 Second Avenue was chosen over First Avenue for logistical reasons. The MTA started the Lower Manhattan Access Study (LMA) in November 1997 in order to determine the best new transport connections to the New York City suburbs. The construction of the Second Avenue Subway from 63rd Street to Lower Manhattan was one of the five build alternatives developed by the study.:6, 7
A 1999 DEIS only proposed new subway service from 63rd Street north up Second Avenue to 125th Street via the Broadway Line to Lower Manhattan, with local and express tracks being switched on the Broadway Line. Second Avenue express trains would run to Lower Manhattan via the Montague Street Tunnel and local trains would run via the Manhattan Bridge and skip Lower Manhattan.:20–21 A spur to Grand Central Terminal was considered, but later dropped due to its infeasibility.:17
Due in part to strong public support, the MTA Board committed in April 2000 to building a full-length subway line along the East Side, from East Harlem to Lower Manhattan.:18 In May 2000, the MTA Capital Program Review Board approved the MTA's 2000–2004 Capital Program, which allocated $1.05 billion for the construction of the Second Avenue Subway.:18 The next year, a contract for subway design was awarded to DMJM Harris/Arup Joint Venture. A new draft statement proposed the full-length line from 125th to 14th Streets. South of 14th Street, the line could either travel under Chrystie Street, St. James Place and Water Street to a terminal in Lower Manhattan, or link to the existing Nassau Street Loop tracks J1 and J2 at Kenmare Street to provide access to Lower Manhattan. The Water Street option was the one eventually chosen.:26–27
On December 19, 2001, the Federal Transit Administration approved the start of preliminary engineering on a full-length Second Avenue Subway. The MTA's final environmental impact statement (FEIS) was approved in April 2004; this latest proposal is for a two-track line from 125th Street and Lexington Avenue in Harlem, down Second Avenue to Hanover Square in the Financial District. The final plan called for the full-length Second Avenue line to carry two services: the T, with a route emblem colored turquoise, as well as a rerouted Q train. Phase 1 rerouted the Q, the Broadway Express via the BMT 63rd Street Line and north along Second Avenue, to the Upper East Side at 96th Street. Phase 2 will extend the rerouted Q train to 125th Street and Lexington Avenue. In Phase Three, the new T train will run from 125th Street to Houston Street. The final phase will extend T train service from Houston Street to Hanover Square in Lower Manhattan.
The 2-mile (3.2 km) first phase was built within budget, at $4.45 billion. Its construction site was designated as being from 105th Street and Second Avenue to 63rd Street and Third Avenue. Deep bore tunneling methods were to be used in order to avoid the disruptions for road traffic, pedestrians, utilities and local businesses produced by cut-and-cover methods of past generations. Stations were to retain cut-and-cover construction. The total cost of the 8.5-mile (13.7 km) line is expected to exceed $17 billion. In 2014, MTA Capital Construction President Dr. Michael Horodniceanu stated that the whole line may be completed as early as 2029, and would serve 560,000 daily passengers upon completion; however, as of December 2016[update], only Phases 1 and 2 would be completed by 2029. The line is described as the New York City Subway's "first major expansion" in more than a half-century. It would add two tracks to fill the gap that has existed since the elevated Second and Third Avenue Lines were demolished in the 1950s. According to the line's final environmental impact statement, the catchment area of the line's first phase would include 200,000 daily riders.
New York voters passed a transportation bond issue on November 8, 2005, allowing for dedicated funding allocated for that phase. Its passage had been seen as critical to its construction, but the bond was passed only by a narrow margin, with 55 percent of voters approving and 45 percent disapproving. At the time, the MTA said that the project would be done in 2012 in case the city's 2012 Summer Olympics bid succeeded, which it had not. On December 18, 2006, the United States Department of Transportation (USDOT) announced that they would allow the MTA to commit up to $693 million in funds to begin construction of the Second Avenue Subway and that the federal share of such costs would be reimbursed with FTA transit funds, subject to appropriations and final labor certification. The USDOT also later gave $1.3 billion in federal funding for the project's first phase, to be funded over a seven-year period. Preliminary engineering and a final tunnel design was completed by a joint venture between AECOM and Arup.
On March 20, 2007, upon completion of preliminary engineering, the MTA awarded a contract for constructing the tunnels between 92nd and 63rd Streets, a launch box for the tunnel boring machine (TBM) at 92nd to 95th Streets, and access shafts at 69th and 72nd Streets. This contract, valued at $337 million, was awarded to S3, a joint venture of Schiavone Construction, Skanska USA Civil, and J.F. Shea Construction. A ceremonial groundbreaking took place on April 12, 2007, at the 99th Street tunnel segment built in the 1970s. At the time, it was announced that passengers would be able to ride trains on the new line by the end of 2013. Actual construction work began on April 23, 2007, with the relocation of utility pipes, wires, and other infrastructure, which took 14 months.
Due to cost increases, several features of the subway were cut back soon after construction started. Notably, the 72nd Street Station was truncated from a three-track, two-platform design to a two-track, single island platform design, paired with a simplification of the connection to the Broadway Line spur. This design change was done before the actual construction started. The MTA also pushed back its completion date to 2014. In its 2008 capital improvement budget proposal, the MTA further postponed completion of Phase 1 to 2015, and in 2009, the MTA rescheduled it again to 2016.
On May 28, 2009, the MTA awarded a $325 million contract to E.E. Cruz and Tully Construction Co., a joint venture and limited liability company, to construct the 96th Street station box. Work on this contract began in July. In June 2009, the first of three contracts for the 86th Street station was awarded for the advance utility relocation work and construction of cut-and-cover shaft areas at 83rd and 86th Streets. After a delay in delivering the TBMs, the MTA's contractors completed the TBM installation on May 14, 2010, and turned it on at the Second Avenue Subway launch box at 96th Street, boring southward to connecting shafts built at 86th and 72nd Streets. On October 1, 2010, MTA awarded a $431 million contract to joint venture SSK Constructors for the mining of the tunnels connecting the 72nd Street station to the existing Lexington Avenue–63rd Street station, and for the excavation and heavy civil structures of the 72nd Street station.:301 A subsequent contract was awarded to Skanska Traylor Joint Venture for excavation of the cavern at the 86th Street station on August 4, 2011. In January 2011, MTA awarded Judlau Contracting a 40-month, $176.4 million contract to rebuild and enlarge the Lexington Avenue–63rd Street station.
The TBM, digging at a rate of approximately 50 feet (15 m) per day, finished its run at the planned endpoint under 65th Street on February 5, 2011. S3 partially disassembled the TBM, backed it out of the tunnel, and placed it in the short eastern tunnel so it could bore again. On March 28, 2011, S3, having completed its task of completing the 7,200-foot (2,200 m) west tunnel to 65th Street, began drilling the east tunnel. The TBM drilling the east tunnel then negotiated the curve onto 63rd Street and broke through the bellmouth at the existing Lexington Avenue–63rd Street station.:31:D-5 The portion of the west tunnel remaining to be created was then mined using conventional drill-and-blast methods, because the curve S3 construction teams would have to negotiate was too tight for the TBM. On September 22, 2011, the TBM completed its run to the Lexington Avenue–63rd Street station's bellmouth.
The MTA opened a Second Avenue Subway Community Information Center for Phase 1 on July 25, 2013. It was located at 1628 Second Avenue between 84th and 85th Streets, near the line's 86th Street station. In the three years that followed, the center was visited over 20,000 times.
The final contract for the entire Phase 1 area was awarded on June 1, 2013. Blasting for the station caverns was finished in November 2013, and the muck houses were taken down at around the same time. In the winter of 2013, many of the tracks and signal panels began to arrive at the construction site, to be installed on the line over the next few years.
On February 24, 2016, the MTA allocated $66 million to speed up the construction of the first phase so that it could open in December. However, by June, the project was not being built at a rate that would allow a December 2016 completion. Concerns about the line's timely opening persisted through October and November, with key systems such as elevators, escalators, and fire alarms not having been tested. The third rail was energized and test trains began running through the new line on October 9, 2016, with weights to simulate rush hour loads; non-revenue Q trains, taken out of service at 57th Street–Seventh Avenue, started running through the subway in November 2016.
In December 2016, a week before the line's opening, the MTA hosted open houses at 96th Street and 86th Street. The entrance to the Lexington Avenue–63rd Street station at Third Avenue, which was completed as part of Phase 1, opened on December 30. The ceremonial first train, with several prominent officials in attendance, ran on New Year's Eve, and trains began serving the line in regular passenger service at noon the next day. About 48,200 passengers entered the new stations on January 1, excluding passengers who toured the line by entering at a station in the rest of the system. During the opening week of operation, trains were running every six minutes during peak hours, and there was no service between 10 p.m. and 6 a.m. The overnight shutdown allowed finishing touches to be placed to avoid leaks and other major issues like those found in the new 34th Street–Hudson Yards station, which had opened a year prior. Overnight service began on January 9, 2017.
Because of the opening of Phase 1, ridership on the Lexington Avenue Line at the 68th Street, 77th Street, 86th Street, and 96th Street stations decreased in January 2017 compared to in January 2016. The Second Avenue Line's three stations and the renovated Lexington Avenue–63rd Street station saw an average weekday ridership of more than 150,000 by the end of January. The 72nd Street station was the busiest of the line's new stations, with an average daily ridership of 44,000. By April, taxi usage in the area also saw a decline of more than 20% compared to before the line's opening. By May 15, 2017, Second Avenue ridership had increased to 176,000 passengers a day, reducing overall usage on the Lexington Avenue Line by 26% while representing a 42% increase from the Second Avenue ridership in January. By February 2018, there were 190,000 riders per weekday, within the 5% margin of error for the 200,000-daily-rider estimate given in the Environmental Impact Statement. Rush-hour ridership was within 2% of projections.
Because of the increasing demand, Q service was increased by one downtown trip in the morning and by one uptown trip in the evening on November 6, 2017. In addition, one northbound R trip was rerouted from the IND Queens Boulevard Line to further boost service. This trip returns southbound in the evening in Q service.
The second phase, between 125th and 96th Streets, was allocated $535 million in the MTA's 2015–2019 Capital Plan for planning, design, environmental studies, and utility relocation. Three new stations will be constructed at 125th Street, 116th Street, and 106th Street, with the existing tunnel at 116th Street being rebuilt to accommodate the new station there. A transfer to the Lexington Avenue Line and an intermodal connection with Metro-North Railroad would be available at the Harlem–125th Street station.:11, 12 The original plan called for the main line to turn west onto 125th Street with tail tracks to Fifth Avenue, while tail tracks would continue north on a spur via Second Avenue to 129th Street. However, the tail tracks to 129th Street, as well as a proposed ancillary building at 127th Street and Second Avenue, were removed in a July 2018 update to the plans.:12 North of 120th Street, the line will be constructed through the use of TBMs. South of 120th Street, the line will utilize the 99th–105th and 110th–120th Streets tunnel sections built during the 1970s, with a cut-and-cover tunnel connecting the segments between 105th and 110th Streets.:2:45
The Phase 2 budget was originally $1.5 billion, which would be used to start construction of the tunnels; the MTA reduced the amount of money allocated in the budget, projecting that the agency would not be able to start construction by the end of the 5-year cycle in 2019. Although the MTA previously expressed concerns about funding the Capital Program, a spokesman stated that the reduction in funding was a result of uncertain timing and not money problems. The delay had upset politicians and residents of East Harlem, who objected to the 3-to-4-year delay.
In March 2016, the MTA began advertising Requests for Proposals (RFP) for three new contracts for the second phase, which were planned to be awarded in summer 2016. In April 2016, the MTA and the State of New York reached a deal to restore funding to Phase 2, with a total of $1.035 billion allocated. On May 24, 2017, the MTA Board increased funding for Phase 2 by $700 million. The new budget of $1.735 billion would allow for a near-term 30 percent match per Full Funding Grant Agreement process. By August 2017, preliminary work on the line was underway, and the engineering firm AKRF was updating the environmental impact study for Phase 2. AKRF had previously prepared the Manhattan East Side Alternatives and the original EIS for the Second Avenue Subway.:48 The design of the project is being done by Phase 2 Partnership, a joint venture of Parsons-Brinckerhoff and STV. The EIS and design will be finished in 2018.:46
A Second Avenue Subway Community Information Center for Phase 2, along 125th Street between Park and Madison Avenues, was planned to open in May 2017. However, the center's opening was delayed to September 18, 2017.
In November 2017, the Regional Plan Association published its Fourth Regional Plan, which, among other things, called for the completion of the full-length Second Avenue Subway. The RPA's plan also called for two additional components to be added to Phase 2. The proposed Phase 2B would extend the Second Avenue Line under 125th Street to Broadway, while the planned phase 2C would be a spur to Third Avenue–149th Street in the Bronx, connecting with the IND Concourse Line. However, these plans have not been acknowledged by the MTA, nor have they been given any funding.
Phase 3, which has no funding commitments, will extend the line southward along Second Avenue from 63rd Street to Houston Street. Upon its completion, a new service will operate running between 125th and Houston Streets. Phases 2 and 3, classified as a high-priority project by the Trump Administration, may cost up to a combined total of $14.2 billion.
Phase 4, which also has no funding commitments, will provide an extension from Houston Street to a permanent terminus, with storage tracks, at Hanover Square. These storage tracks, initially recommended in the SDEIS, would allow for the storage of four trains, and they would run south of Hanover Square from Coenties Slip to a traffic island located near Peter Minuit Plaza at a depth of 110 feet (34 m).:16 The Hanover Square terminal is only planned to be able to turn back 26 trains per hour instead of 30 as less capacity will be needed on the line south of 63rd Street.:26 The Hanover Square station will be deep enough to allow for the potential extension of Second Avenue Subway service to Brooklyn through a new tunnel under the East River.
The stations on the line were built so that they are more wide open than most other underground subway stations in the system; because of this, Horodniceanu likened the Second Avenue Subway stations to the stations on the Washington Metro. All of the stations of the line will have their platforms be 615 feet (187 m) long, with their overall footprint being between 800 feet (240 m) and 1,400 feet (430 m) to provide space for the necessary power stations and ventilation plants.:14 The tracks themselves are built atop rubber padding so as to reduce the noise from the trains.
In August 2006, the MTA revealed that all future subway stations—including stations on the Second Avenue Subway and the 7 Subway Extension, as well as the new South Ferry station—would be outfitted with air-cooling systems to reduce the temperature along platforms by as much as 10 °F (6 °C). In early plans, the Second Avenue Subway was also to have platform screen doors to assist with air-cooling, energy savings, ventilation, and track safety, but this plan was scrapped in 2012 as cost-prohibitive.
The construction of the 8.5 miles (13.7 km) of the Second Avenue Subway underneath densely populated Manhattan will require the use of several construction methods, depending on the section of the line. The line's tunnels will largely consist of twin tunnels with diameters of up to 23.5 feet (7.2 m).:1 About 90% of the tunneling is to be performed by tunnel boring machines. The rest will be done using the cut-and-cover method, or through the use of mined drill-and-blast, for sections averaging 275 meters (902 ft) in length, namely the station boxes. The methods used to construct the sections of the line were confirmed in 2003, with a modification of the section north of 120th Street announced in 2016.:2:14

Phase 1 of the Second Avenue Subway was constructed between the Lexington Avenue–63rd Street station on the 63rd Street Lines and an existing tunnel segment between 99th Street and 105th Street, with a terminal station at 96th Street. In Phase 1, tunneling was completed between East 63rd Street and East 92nd Streets through the use of TBMs. The TBM launch box was 814-by-75-foot-wide (248 by 23 m), and is now part of the 96th Street station. Two access shafts were constructed for the 72nd Street station. Slurry or diaphragm walls, 1.1 meters (3.6 ft) wide and 6.1 meters (20 ft) long and about 35 meters (115 ft) deep, were built alongside the sections between East 93rd and 95th Streets. Since the rock is shallower between East 91st and 93rd Streets, 1.1-meter-diameter (3.6 ft) secant piles did the same work at shallower depths. Earth excavation was conducted between walls once they were installed, and box structures were built using a bottom-up construction method. Temporary decking constituted the top of the boxes, and the decking both braced the excavation and supported the walls and Second Avenue traffic.
The stations at 86th and 72nd Streets were mined. This was challenging, given the number of expensive high rise properties in their vicinities. The 96th Street cut-and-cover station was about 15 meters (49 ft) deep, making it one of the shallowest stations being built on the line; the shallowness was so that the new line could align with the preexisting piece of subway tunnel built in the 1970s between 99th and 105th Streets. Stations at the two mined stations are between 25.9 and 27.4 meters (85 and 90 ft) deep in rock. The construction method that was used was supposed to ease concerns for buildings above the station sites, because only two shafts were required for excavation.
Of the below-ground obstacles, Arup director of construction David Caiden stated: "It's a spaghetti of tunnels, utilities, pipes and cables—I've never seen anything like it." Complicating the process, the project must go over, or under, subway lines, Amtrak railway lines, and the Queens-Midtown Tunnel linking Manhattan and Queens, in later phases. In addition, there were geological anomalies along the way of Phase 1. Manhattan's geology changes along the subway's length, passing through rock and soft ground, consisting of sands, silts, and clays over Manhattan schist, and there are faults and shear zones as well as fractured rock. Hard-rock TBMs 6.7 meters (22 ft) in diameter, 450 feet (140 m) in length, and 485 short tons (433 long tons) in weight were used to tunnel during the first phase, progressing at a rate of about 20 meters (66 ft) per day. The tunnels near the 125th Street station would need to go through soft soil in addition to diving underneath the existing IRT Lexington Avenue Line. The soft-soil tunnels are in contrast to the hard-rock bored tunnels south of 92nd Street and the cut-and-cover tunnels north of that point (necessitated because Manhattan's rock profile drops sharply north of 92nd Street).:14
Phase 2 will extend the line north from the 96th Street station to the Harlem–125th Street subway station at Lexington Avenue. North of 120th Street, it will be constructed through the use of TBMs. The TBM Launch Box will be located between 121st Street and 122nd Street on Second Avenue. The TBMs will head north under Second Avenue to 118th Street:12 before turning slightly east to curve under the East River Houses, turning west on 125th Street, crossing Lexington Avenue, before ending 525 feet (160 m) west of Fifth Avenue to accommodate storage tracks. South of 120th Street, the line will utilize a tunnel section built during the 1970s, located between 110th Street and 120th Street. This section will have tracks and other essential equipment installed, like that of the rest of the line. Since it was deemed uneconomical to use TBMs, cut-and-cover will be used to connect the existing tunnel section to the bored section to the north (at 120th Street) and to the portion of the line already in operation to the south (at 105th Street).:2:45 A bellmouth will be constructed to allow for a future extension to the Bronx. The storage tracks west of the 125th Street station would replace the storage tracks north of the 96th Street station, which would then be used in revenue service as part of Phase 2.:48
A transfer will be constructed at the eastern end of the Second Avenue Subway's Harlem–125th Street station to connect to the IRT Lexington Avenue Line's 125th Street station. A new lower-level mezzanine will house the connection between the two stations, directly connecting to the downtown platform for Lexington Avenue service. The direct connection to the staircases to the upper level will be rebuilt. At the western end of the station, a transfer will be built to connect to the Metro-North Railroad's Harlem–125th Street station. An elevator, stairs, and escalators would connect the two stations.:58
Phases 3 and 4 will extend the line south from 63rd Street to Houston Street and Hanover Square, respectively. As part of Phase 3, a connection to the IND 63rd Street Line would be built, allowing for non-revenue moves into Queens. This connection will be constructed through underground drilling and blasting. Bellmouths already exist for this connection east of the Lexington Avenue–63rd Street station. This section, like the rest of the line, will mainly consist of a two-track line. However, between 21st Street and 9th Street, two additional tracks will be constructed on either side of the main alignment to allow for the storage of eight trains. This location was selected due to the sufficient depth of the area.:60 The third phase would pass above several East River tunnels, including the 63rd Street Tunnel, the 60th Street Tunnel, the 53rd Street Tunnel, the Steinway Tunnel at 42nd Street, and the East River Tunnels at 32nd and 33rd Streets.:5B·14
Like Phase 1, the sections between stations will largely be constructed through the use of TBMs, while stations will be constructed through cut-and-cover and mining, allowing for the construction of station caverns, shafts, and entrances. Five transfers are planned to connect stations on the Second Avenue Line and nearby stations on adjacent lines, increasing travel options for passengers. The transfer at Grand Street will require the construction of a mezzanine below the existing station, allowing for a vertical transfer to be constructed. The existing station will have to be rebuilt to accommodate the increased volume of passengers using the station. The Houston Street station's transfer to the Second Avenue station of the IND Sixth Avenue Line would require some construction within the existing station. The remaining three transfers are being proposed, and will be constructed, baring the increased cost of their construction. The transfer to the BMT Canarsie Line's Third Avenue station would consist of a passageway that will be 200 feet (61 m) long. The most complicated of the transfers will be the connection between the 42nd Street station and the Grand Central station on the IRT Flushing Line. To allow for the connection to be built, a 900-foot long tunnel would be built under 42nd Street from the west side of Third Avenue to Second Avenue. The Flushing Line station might have to be significantly reconstructed in anticipation of the increased volume of passengers and due to Americans with Disabilities Access requirements for the transfer. To allow for necessary vents and emergency exits to be built, cut-and-cover would be used. The final transfer would be between the 55th Street station and the Lexington Avenue–53rd Street station on the IND Queens Boulevard Line. Either shielded mining or cut-and-cover would be used to complete the connection. The existing station would have to be modified to allow for the transfer passageway to be built.:55–60
Three construction options were evaluated during the project's Environmental Impact Study for the portion of the line between 11th Street and Hanover Square. One option known as the Shallow Chrystie Option would mainly use cut and cover, while the Deep Chrystie Street and Forsyth Options would use a combination of tunneling by Earth Pressure Balance Machines (EPBMs) and cut and cover. The Shallow Chrystie Option would have used the existing Confucius Plaza tunnel section between Canal and Division Streets, and like the plan from the 1970s, there would have been a cross-platform transfer to the existing Grand Street station, with the transfer expected to be heavily used. However, this option would require digging up Sara Delano Roosevelt Park to the east as Chrystie Street is not wide enough to fit four tracks. Under this option, a track connection would be built to allow trains from Second Avenue to run via the Manhattan Bridge north tracks to allow service to Brooklyn. The Forsyth Option would curve below the park to Forsyth Street and the station would be built under Forsyth Street, requiring a 200-foot transfer passageway that would be less convenient than the other options. The Deep Chrystie Option would have the Second Avenue Subway run deeper underground, running underneath the existing Grand Street station, with a mezzanine in between the two stations. In order to allow for sufficient room for stairways to transfer to the Second Avenue Line, the Grand Street station would be widened to have twenty foot wide platforms. No track connection would be built under this option, and the Confucius Plaza tunnel section would not be used for subway service, but it instead might be used for ancillary subway facilities. Currently, this is the preferred option.
South of the terminal at Hanover Square, two tail tracks will be constructed through the use of a TBM to allow for the storage of four trains. The tracks would be built at a depth of about 110 feet (34 m) under Water Street, allowing the line to be deep enough to tunnel under the East River for a possible future extension into Brooklyn. Cut-and-cover would be used to build a vent facility at a traffic island located at Water and Whitehall Streets.:50, 60:2–11
There was controversy over the high cost of the line as a whole. The project was divided up into four phases, in part, to maximize the ability of the project to receive funding from the Federal Government as part of the Department of Transportation's New Starts Program. The initial projections for the cost of the line were made in the 2004 FEIS, with Phase 1 estimated to cost $3.8 billion, Phase 2 estimated to cost $3.4 billion, and Phases 3 and 4 each estimated to cost $4.8 billion.:3
Phase 1 ended up costing $500 million over its original budget of $3.8 billion—still a very high price compared to other new subway systems worldwide. Regulations set by the Buy America Act forced the MTA to purchase materials made in the United States, which led to objections when an MTA contractor bought a fire suppression system made in Finland. Finally, the private and public sector could not cooperate smoothly on the project, further raising costs. Of the $4.5 billion cost for Phase 1, $2.4 billion was allocated to building the three new stations and renovating the Lexington Avenue–63rd Street station. Meanwhile, $500 million was spent on design and engineering, and another $734 million was for building tunnels between the stations, tracks, signals, and trackside systems. The rest of the cost, $800 million, was spent on "construction management, real estate, station artwork, fare-collection systems and other sundry items." The stations' cost was magnified by the depth of the stations and the enormity of the caverns that needed to be excavated. The Second Avenue Subway stations have full-length mezzanines, like the original IND but unlike other deep-level projects such as London's Crossrail.
In December 2016, after it was announced that Phase 2 might cost $6 billion, transit experts expressed concern that the Second Avenue Subway might be so excessively costly as to preclude construction of Phases 3 and 4, as well as future expansions. One expert stated that the Phase 1 project was the most expensive subway project in the world, and that compared to other subway systems around the world, the cost of building new subways in New York City was much higher. The Second Avenue Subway's per-mile construction cost is higher than that of other projects in similar cities like London's Crossrail and Paris's Grand Paris Express, which themselves are among the most expensive underground-railway projects in the world. MTA officials stated that the Second Avenue Subway cost as much as it did only because of the complex underground infrastructure in Manhattan, as well as the fact that the New York City Subway runs all the time.
The opening of Phase 1 extended Q service to 96th Street from its former terminal at 57th Street. The Q service has a rush-hour service frequency of 7 to 10 trains per hour; by contrast, the IRT Lexington Avenue Line's express tracks (4 and 5 trains) have an estimated rush-hour frequency of 30 trains per hour, or one train approximately every 2 minutes in each direction. As part of the 2004 Final Environmental Impact Study (FEIS) for the line, Q service was planned to have a frequency of 14 trains per hour during rush hours,:5B·20 but this was revised due to MTA schedule changes. A few rush hour N trains that formerly short-turned at 57th Street began to run to 96th Street on January 3, 2017; the northbound trips are labeled as Q trains via the Sea Beach Line to reduce passenger confusion. Starting on November 6, 2017, one northbound R train has served the line during weekday mornings, boosting service.
In Phase 2, all current services will be extended to 125th Street and Lexington Avenue. As part of the 2004 FEIS, it was planned for Q service to be increased to 19 trains per hour to accommodate the projected increase in ridership.:5B·20 In order to allow for the construction of Phase 3, bellmouths have been constructed at the turnoff to the BMT 63rd Street Line.
When the construction of Phase 3 is completed, a new T service will operate from Harlem–125th Street to Houston Street. After Phase 4 opens, T service will run the full length of the line, from Harlem–125th Street to Hanover Square.:5B·29 to 5B·30 T service is planned to operate at a frequency of 14 trains per hour during rush hours, with the combined frequency north of 72nd Street with Q service being 28 trains per hour. With the opening of Phase 3, the frequency of Q service is planned to be reduced from 19 to 14 trains per hour.:5B·20
The MTA decided to designate the future service with the letter T, in part because:
The T's route emblem is colored turquoise (hex triplet #00ADD0, which could also be considered robin's egg blue or teal) because the color had also been used for the JFK Express in the past. In 2011, turquoise was considered "the color of the year", and at the time of the color's selection in the 2000s, it was also considered a very upscale color.
Three stations are part of Phase 1, which opened on January 1, 2017. Three more are planned for Phase 2 (including one transfer to an existing line); six more in Phase 3 (including up to four transfers); and four more in Phase 4 (including one transfer).
