The two center tracks, which are not used in revenue service, dead-end just east of the Second Avenue station. They were built as part of the IND's proposed expansion in the 1930s , and would have merged with the never-built IND Worth Street Line and then entered Brooklyn. The line would have run to Utica Avenue in Brooklyn if it had been completed. Other provisions for unbuilt lines exist at

At Seventh Avenue , the southbound track is above the northbound track (the same is true on the Queens Boulevard Line, though north is the opposite direction from the Sixth Avenue Line). These tracks are used by the B and D express trains. The express tracks from Columbus Circle then turn south to go under Sixth Avenue, merging with
2254-591: The Interborough Rapid Transit Company (IRT)'s Sixth Avenue elevated , which closed in 1939. The first section of the line opened in 1936 from West Fourth Street to East Broadway with service provided by Eighth Avenue Line trains. This section was initially referred to as the Houston-Essex Street Route. The Sixth Avenue subway was completed in 1940, providing service north of West Fourth Street, connecting to

The connection was used for a time to move equipment to and from the BMT Eastern Division , but was not used in regular service again until budget cuts forced a reroute of
2450-537: The M along the connection starting on June 27, 2010. The M had been rerouted to replace the discontinued V route on the IND Sixth Avenue Line and the IND Queens Boulevard Line to Forest Hills–71st Avenue . A plan similar to the Chrystie Street Connection was proposed as part of the Second Avenue Subway (SAS) under the Board of Transportation's 1944–1948 Capital Program, with connections from
2548-670: The New York City Board of Estimate requested a $ 25.5 million federal loan for the construction of the Sixth Avenue line. The first portion of the line to be constructed was then known as the Houston–Essex Street Line, which ran under Houston, Essex, and Rutgers Streets. The contract for the line was awarded to Corson Construction in January 1929, at which time the city began evicting 10,000 residents within
2646-615: The Queens Boulevard Line and the Eighth Avenue Line. Initially, the Sixth Avenue Line carried only local service, since there were no express tracks between 34th Street and West 4th Street. In 1967 and 1968, the Chrystie Street Connection was completed, connecting the line with former BMT lines in Brooklyn via the Manhattan Bridge and with the BMT Jamaica Line over the Williamsburg Bridge. Two new stations at 57th Street and Grand Street, as well as
2744-535: The Second Avenue station, and were planned to extend into Brooklyn and beyond as part of a never-built major system expansion called the IND Second System . Those tracks still exist at Second Avenue station, but now connect to the local tracks west of the station. The two tracks on the north side of the Manhattan Bridge formerly carried trains to the BMT Broadway Line , which now connects to
2842-586: The 1975–76 New York City fiscal crisis and extreme MTA fare revenue fluctuations. The tracks at 57th Street were originally built for a proposed extension under Central Park to Harlem . The stub-end tracks were eventually connected to the IND 63rd Street Line when the latter opened in October 1989. The 63rd Street line only extended to the 21st Street–Queensbridge station in Queens, and did not connect to any other lines in that borough. The Q train served
2940-461: The 21st Street–Queensbridge station to the IND Queens Boulevard Line in Queens began in December 1990, and construction began on September 22, 1994. The Connector came into regular use on December 16, 2001. A new Sixth Avenue local service, the V, was introduced operating local via Sixth Avenue and terminating in the center tracks of the Sixth Avenue Line's Second Avenue station. The V ran local on

3136-528: The 33rd Street terminal were located only two blocks away, rendering the 28th Street stop unnecessary. It was demolished to make room for the IND tracks below. The IRT's Sixth Avenue elevated ultimately closed in December 1938, just before the Sixth Avenue subway was completed. In addition to threading around the H&;M tunnel, the line had to pass over the BMT Canarsie Line along 14th Street, over
3234-470: The 57th Street station and the portion of the Chrystie Street Connection connecting the line with the Williamsburg Bridge opened. Service on the KK was inaugurated, running from 57th Street to 168th Street on the BMT Jamaica Line . B service was extended during non-rush hours from West Fourth Street to 57th Street. D trains began running express via the Sixth Avenue Line at all times. The Program for Action ,
3332-470: The 63rd Street extension on weekdays and the B train stopped there on the weekends; both services used the Sixth Avenue Line. The Q train, a part-time express within Brooklyn via the BMT Brighton Line, ran along the Sixth Avenue Line between 1988 and 2001, when the Manhattan Bridge south tracks were closed for reconstruction. Planning for the 63rd Street Line's $ 645 million connection from

B service operates weekdays only via the Brighton Line express tracks to Brighton Beach, replacing the <Q> express on the Brighton Line. D service operates 24/7 along the West End Line because residents of Bensonhurst , a neighborhood located near the West End Line, wanted full-time direct subway service to Manhattan. The 2015–2019 Metropolitan Transportation Authority Capital Plan called for
3528-759: The BOT's successor, the New York City Transit Authority , had asked the city for $ 37.3 million to begin constructing the Chrystie Street Connection. In 1955, the TA recommended that the Board of Estimate approve a contract to reconstruct a junction near the DeKalb Avenue station , on the Brooklyn side of the Manhattan Bridge, to eliminate a bottleneck there. This was the first step in a larger plan to improve transit service between Brooklyn and Manhattan. The Chrystie Street Connection would utilize
3626-481: The Chrystie Street Connection unavailable for through trains, and made the Grand Street station a terminal for Grand Street Shuttle service to Broadway–Lafayette Street . The Manhattan Bridge reopened fully in 2004. The Chrystie Street Connection returned to full revenue service on June 28, 2010. The Manhattan Bridge connection continues to be used by the B and D services. The Williamsburg Bridge connection
3724-516: The Chrystie Street Connection was the first part of the long-planned Second Avenue Subway to be opened to service. The connection is one of several vestiges of early efforts to build the Second Avenue Subway, and before the connection was built, the original IND construction for the line included a recession in the ceiling at Second Avenue station and a short tunnel under Bowery .

3920-465: The Grand Street station opened on November 26, 1967, almost exactly 10 years after the project began. The Williamsburg Bridge connection and 57th Street station opened on July 1, 1968. The opening of the connection allowed greater flexibility in routings along BMT lines in Brooklyn. The Manhattan Bridge connection eliminated a bottleneck where trains using three of the four BMT Southern Division lines from Coney Island–Stillwell Avenue , were forced to use
4018-416: The H&M was cut back to 28th Street to allow for construction on the subway to take place. The 33rd Street terminal was moved south to 32nd Street and reopened on September 24, 1939. The city had to pay $ 800,000 to build the new 33rd Street station and reimbursed H&M another $ 300,000 to the H&M for the loss of revenue. The 28th Street station was closed at this time because the southern entrances to

However, that May, construction was postponed because of fears that it would disrupt the Catskill Aqueduct , one of the New York City water supply system 's crucial water mains to Brooklyn and Queens. The NYCBOT wanted to start work on
4214-509: The IND typically installed express–local crossovers beyond the fronts of the station platforms, an anomaly in the track layout was created when the Chrystie Street Connection was built. A crossover exists west of Broadway–Lafayette Street only on the northbound side, allowing trains from the Manhattan Bridge to reach the Eighth Avenue local tracks at West Fourth Street but not vice versa. As a result, unusual routings are required whenever

In 2004, the Brooklyn routes and terminals of the B and D trains were swapped as part of the Manhattan Bridge reconstruction from 1986 to 2004. The two tracks that connect to the Williamsburg Bridge split from
4410-440: The Manhattan Bridge connection opened. The second occurred on Monday, July 1, 1968, when the Williamsburg Bridge connection opened. Additionally, for the 1967 opening, every service in the system was labeled with a letter or number and a color. On November 15, 1967, the TA published a subway map showing which routes would be changed when the Manhattan Bridge connection opened. After 940 new signs had already been installed across

The new connection thus permitted IND Sixth Avenue Line trains from Midtown to use the BMT lines toward Coney Island, while preserving Nassau Street service via the Montague Street Tunnel. Trains from the BMT Jamaica Line and other BMT Eastern Division lines also gained
4606-571: The NX and RJ quickly disappeared (April 12, 1968, and June 28, 1968, respectively), although the RJ was replaced with a shorter rush hour R service between Chambers Street and 95th Street-4th Avenue in Brooklyn. The KK (since renamed the K ) was discontinued in 1976 as a money-saving measure, ending service via the Williamsburg Bridge connection. Reconstruction of the Manhattan Bridge occurred from 1986 to 1988, in 1995, and from 2001 to 2004. At times, this made

At this time, the F, which ran express along the Queens Boulevard Line, was rerouted to operate via the 57th Street station and the 63rd Street line north of the 47th–50th Streets–Rockefeller Center station, rather than via the 53rd Street tunnel. Both the 63rd Street and the 53rd Street lines merge into the Queens Boulevard Line in Queens. On June 28, 2010,

The Sixth Avenue Line, constructed in stages during the 1930s, was the last trunk line built by the Independent Subway System (IND) before it was incorporated into the modern-day New York City Subway. It was more difficult to build than other subway trunk lines in New York City because construction had to proceed around, over, and under existing tunnels and elevated structures. The Sixth Avenue Line replaced

After passing through 47th–50th Streets–Rockefeller Center , the two southbound tracks cross each other; the tracks from Columbus Circle become the two center express tracks, and the tracks from the Queens Boulevard Line are the two outside local tracks. South of 42nd Street–Bryant Park is a large interlocking with six crossovers and switches. The original express tracks ended just to
7350-524: The outer tracks of Jay Street–MetroTech . New York City mayor John Francis Hylan 's original plans for the Independent Subway System (IND), proposed in 1922, included building over 100 miles (160 km) of new lines and taking over nearly 100 miles (160 km) of existing lines. The lines were designed to compete with the existing underground, surface, and elevated lines operated by the Interborough Rapid Transit Company (IRT) and Brooklyn–Manhattan Transit Corporation (BMT). The IND Sixth Avenue Line
7448-495: The project would be finished in three years. Workers were constructing the segment of the Manhattan Street connection beneath the existing Nassau Street Line by 1959. Concrete workers went on strike while the connection was under construction, raising concerns that the BMT tunnel could be undermined; to prevent the tunnel from collapsing, the concrete workers' union made an exception allowing workers to pour concrete for
7546-560: The reconstruction of the DeKalb Avenue station in Brooklyn. The second phase of construction was the Chrystie Street Connection , which would connect the BMT lines coming over the Manhattan Bridge and the Williamsburg Bridge with the IND Houston Street Line. There was also to be a new two-track spur line between West 52nd and 58th Streets with a terminal at 57th Street to allow trains to short turn. The two projects would allow 45 additional trains per hour, carrying
7644-552: The section between 33rd and 39th Streets first so that the engineering issues with the H&M tubes and water main could be resolved. In January 1932, the city announced an agreement with the New York City Water Supply Board . The IND wanted to start construction on the Sixth Avenue line by June so that some of the projected train traffic on the Eighth Avenue line, which was slated to open that year, could be rerouted through Sixth Avenue instead. In 1933,
7742-408: The section of the Manhattan Bridge connection from Delancey to Stanton Street . A groundbreaking ceremony was held on November 25, 1957, with Mayor Robert F. Wagner, Jr. and TA officials in attendance. The project was constructed in conjunction with the addition of express tracks on the Sixth Avenue Line between 34th Street and West 4th Street, adding capacity to the line. It was expected that
7840-549: The six parts of the Second Avenue Subway that were built in the 1960s and 1970s—the other four parts being the BMT 63rd Street Line , two unused subway segments under Second Avenue in East Harlem (one of which was connected to the 63rd Street line for Phase 1 of the Second Avenue line, which opened in 2017 ), and an unused subway segment under Confucius Plaza just to the south. The Chrystie Street Connection would have facilitated cross-platform and track interchanges between
7938-479: The south at 34th Street–Herald Square and some services switched to the local tracks at the interlocking. This was done because the PATH 's Uptown Hudson Tubes already existed under Sixth Avenue south of 33rd Street , and so the Sixth Avenue Line local tracks were built on each side of PATH. The section between West Fourth Street–Washington Square and 34th Street–Herald Square, the only express section of this line,
8036-440: The southbound express track crossed over the southbound local track at a grade-separated flyover between 42nd and 47th–50th Streets. Bellmouth tunnels north of 47th–50th Streets were built to allow for a future extension under Central Park and along Morningside Avenue to 145th Street. This extension was part of the Board of Transportation's long-range program, and was estimated to cost $ 34.914 million as of August 1940. Construction
8134-497: The three stations added with the opening of phase 1, is one of the few completed sections of the project. The two tracks that run the full length of the connection begin as a continuation of the IND Sixth Avenue Line express tracks east of Broadway–Lafayette Street. These tracks include the line's only station, Grand Street , and connections to the two northern tracks over the Manhattan Bridge. The IND Sixth Avenue Line express tracks formerly continued east, ending slightly east of
8232-468: The tracks on the south side of the bridge. The south side tracks had been connected to the BMT Nassau Street Line , carrying the Nassau Street Loop service via Chambers Street from 1915. The northern tracks of the bridge saw heavier traffic loads because it led to Midtown Manhattan, compared to the southern tracks, which made three stops in Lower Manhattan before returning to Brooklyn. As
8330-638: The tracks were intended to travel under the East River and connect with the never-built IND Worth Street Line in Williamsburg, Brooklyn. Just after midnight on April 9, 1936, trains began running under the East River via the Rutgers Street Tunnel, which connected the Houston-Essex Street Line with the north end of the Culver Line at a junction with the Eighth Avenue Line north of Jay Street–Borough Hall . E trains were sent through
8428-415: The tunnel. In 1962, the construction of an extension of the Sixth Avenue Line to a new terminal at 57th Street was announced. This would be the final major component of the plan to increase Brooklyn to Manhattan capacity. In February 1963, construction of the tunnel for the Chrystie Street Connection was 95 percent complete. It was expected that contracts for track work would be put out for bidding in about
8526-503: The tunnels leading to Penn Station, under the four-track BMT Broadway Line at Herald Square, over the IRT Flushing Line at 41st Street, and under the 42nd Street Shuttle . Even though the line had to pass around multiple transit lines, the grades were kept to a minimum. The line included four-track stations at West Fourth, 34th, 42nd, and 47th–50th Streets. There were four sets of crossovers between 34th and 42nd Streets, and
8624-490: The two pairs of tracks in each direction are connected with diamond crossovers. A flying junction just to the south connects the local tracks of the Sixth and Eighth Avenue Lines. The Sixth Avenue Line then turns east under Houston Street with an express station at Broadway–Lafayette Street . East of Broadway–Lafayette Street, the express tracks turn south and use the Chrystie Street Connection to Grand Street before crossing
8722-566: Was built as a four-track tunnel north of 33rd Street, but there were only two tracks south of that street. The work largely involved cut-and-cover excavations, although portions of the subway had to be tunneled through solid rock. Builders had to use very small charges of dynamite so that they would not disrupt the H&M tunnels alongside the route, the street and elevated line above, and the water main below. The Sixth Avenue Elevated had to be underpinned during construction, adding another $ 4 to $ 5 million to construction costs. The Catskill Aqueduct
8820-403: Was concurrent with the opening of the new express tracks on the Sixth Avenue Line between West Fourth Street–Washington Square and 34th Street , providing additional capacity for the extra trains on the IND via the connection. The following service changes were made, affecting about 200,000 passengers: These changes were reportedly so confusing to some motormen that on November 28, 1967,
8918-475: Was designed to replace the elevated IRT Sixth Avenue Line . However, since the Sixth Avenue corridor was such an important subway link, the elevated remained open while construction on the Sixth Avenue subway proceeded. In 1924, the IND submitted its list of proposed subway routes to the New York City Board of Transportation (NYCBOT), which approved the program. The IND's program consisted of two lines underneath Sixth Avenue in Manhattan. The first line would be
9016-500: Was expected to start some time after 1946. On December 15, 1940, local subway service began on Sixth Avenue from the West Fourth Street subway station to the 47th–50th Streets station with track connections to the IND 53rd Street Line. The construction of the Sixth Avenue Line cost $ 59.5 million. The opening of the Sixth Avenue Line relieved train traffic on the Eighth Avenue Line, which was used by all services except for
9114-413: Was extended via the new express tracks and the connection to the BMT West End Line in Brooklyn. D service was routed via the connection and onto the BMT Brighton Line instead of via the Culver Line. It only ran express during rush hours. F service was extended from Broadway–Lafayette Street during rush hours, and from 34th Street during other times to Coney Island via the Culver Line. On July 1, 1968,
9212-400: Was fully reopened to traffic. It had been subjected to different closures for six years for the construction of the line. Later that year, the tracks in the new connection were laid. In contrast to subway tracks on existing lines, which contained wooden cross ties , the new tracks were installed on rubber pads attached to the concrete track bed, thereby dampening noise from trains. In 1965,
9310-476: Was introduced to provide service between Sixth Avenue and the Concourse Line. The F train, running between Parsons Boulevard and Church Avenue via Sixth Avenue, was created to provide express service between Sixth Avenue and Queens. Finally, the E train was cut back from Church Avenue to Broadway–Lafayette Street, running to Queens via the Eighth Avenue Line. On April 19, 1961, ground was broken for
9408-412: Was located around 200 feet (61 m) below the avenue's surface, and workers on the new subway had to be careful to not cause any cracks in the aqueduct. As part of the construction of the IND line, the H&M's 14th Street and 23rd Street stations had to be rebuilt to provide space for the IND's 14th Street and 23rd Street stations, which would be located at a similar elevation. The 19th Street station
9506-499: Was not affected because the IND tracks were located below the H&M tracks at that point. However, the 33rd Street station had to be relocated to the south of its existing location, above the new IND line. The IND platforms were to be located at the same elevation as the present H&M station, and there was no room to build a new subway station either above or below the level of the existing H&M station. The H&M's 33rd Street terminal closed on December 26, 1937, and service on
9604-411: Was originally built as a two-track subway with the provision to expand to four tracks later. The express tracks were added in the 1960s in conjunction with the Chrystie Street Connection project. As a result, they are placed under the local tracks and PATH using the deep-bore tunneling method. At West Fourth Street–Washington Square, the express tracks return to the same level as the local tracks, and
