Second Avenue Subway Line
L.K. Comstock is leading the 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 includes 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 includes modification of existing facilities and systems to ensure connectivity with the Second Avenue subway system. Crews also will construct three rail crossovers along this route, which will allow trains to switch tracks in case of emergency.
The project is 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 has a targeted completion date in the fall of 2016. This work is 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 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. The line is being built in phases; the first phase of the Second Avenue Subway will provide service from 96th St. to 63rd St.
When complete in December 2016, the first phase will:
- serve more than 200,000 daily riders
- decrease crowding on the Lexington Avenue Line by as much as 13%, or 234,000 fewer riders on an average weekday; and
- reduce travel times by up to 10 minutes or more (up to 27%) for those on the far East Side or those traveling from the East Side to west Midtown.
