L.K. Comstock led a joint venture to construct the track and systems for Phase I of New York City Transit’s Second Avenue Subway.
The 55-month, $261.9 million project included installing the track, train signals, traction power and communications on the newly bored, two-track system on the East Side of Manhattan between 105th Street and the existing subway station at 63rd Street. Additional project work included modifying existing facilities and systems to ensure connectivity with the Second Avenue subway system. Crews also constructed three rail crossovers along this route, which allows trains to switch tracks in case of emergency.
The project was a joint venture between L.K. Comstock and Skanska USA’s civil construction business unit. L.K. Comstock was awarded a 66.67 percent share, about $175 million of the project total. Work on the project commenced in February 2012 and was substantially completed by the end of 2016, in time for a New Year's Day opening in 2017. This work was part of the MTA’s $4.45 billion project to build Phase 1 of the Second Avenue Subway, the first major expansion of the New York City Transit subway system in more than 50 years.
The Second Avenue Subway reduces overcrowding and delays on the Lexington Avenue line, improves travel for both city and suburban commuters, and provides better access to mass transit for residents of the far East Side of Manhattan. The line is being built in phases; the first phase of the Second Avenue Subway provides service from 96th Street to 63rd Street.
The first phase serves more than 200,000 daily riders and decreases crowding on the Lexington Avenue Line by as much as 13 percent, or 234,000 fewer riders on an average weekday. It reduces travel times by up to 10 minutes or more (up to 27 percent) for those on the far East Side or those traveling from the East Side to west Midtown.
