SAS construction

The Second Avenue Subway project will include a two-track line along Second Avenue from 125th Street to the Financial District in Lower Manhattan. It will also include a connection from Second Avenue through the 63rd Street tunnel to existing tracks for service to West Midtown and Brooklyn. Sixteen new ADA accessible stations will be constructed.

The Second Avenue Subway will reduce overcrowding and delays on the Lexington Avenue line, improving travel for both city and suburban commuters, and provide better access to mass transit for residents of the far East Side of Manhattan. Stations will have a combination of escalators, stairs, and in compliance with the Americans with Disabilities Act, elevator connections from street-level to station mezzanine and from mezzanine to platforms.

Under the current plan, the project will be built in four phases. Phase One will include tunnels from 105th Street and Second Avenue to 63rd Street and Third Avenue, with new stations along Second Avenue at 96th, 86th and 72nd Streets and new entrances to the existing Lexington Av/63 Street Station at 63rd Street and Third Avenue.

The first construction contract involves the construction of new tunnels between 92nd and 63rd Streets, the excavation of the launch box for the tunnel boring (TBM) machine at just south of 92nd to 95th Streets, and access shafts at 69th and 72nd Streets. These shafts will be used for the subsequent construction of the 72nd Street station. Contract One is expected to take about 45 months to complete.

Phasing Plan

Phase One subway service, which is projected to carry over 200,000 weekday riders, will entail a reroute and extension of the existing Q subway service in Manhattan. Q subway service will operate along Second Avenue from 96th Street to 63rd Street, where it will divert west along the existing 63rd Street line, stopping at the Lexington Avenue/63rd Street Station, where riders will be able to transfer to the F subway line. It will then continue west under Central Park on tracks that are currently not being used for passenger service and then head south, stopping at express stations along Seventh Avenue and Broadway before crossing the Manhattan Bridge to Brooklyn. Passengers traveling to Lower Manhattan on this route will be able to transfer for local service to destinations south of Canal Street. Alternate service will be provided to replace service to Astoria, Queens.

Final Design for Phase One started in April 2006. The first construction contract was awarded in March 2007.
