The consortium formed by Skanska, Traylor Bros, and Walsh Construction has signed a contract worth over one billion dollars with the Metropolitan Transportation Authority (MTA) for the New York metro extension.
The contract is part of Phase 2 of the Second Avenue Subway project in New York and involves the construction of 2.83 km of track with three new stations, connecting East Harlem and Harlem to Manhattan’s rapid transit network.
New York metro extension, operational by 2030
The work includes structural connections to existing tunnels, excavation and earthwork support, the installation of temporary road platforms to maintain existing traffic, the construction of ground-level and underground structures for two station entrances, as well as utility relocation and restoration work.
According to the project, the work will be completed in 2030, when this extension of the New York subway will become operational.
The design-build contract covers the extension of the Q subway line on Second Avenue, from 96th Street to 125th Street, and includes the construction of a new complex underground infrastructure in Manhattan.
The line extension will improve connectivity on Manhattan’s East Side, reduce overcrowding on the Lexington Avenue line, and create a direct link between northern Manhattan and downtown, integrating connections with the 4/5/6 lines and the Metro-North network.
Phase II will extend the Q line into East Harlem and Harlem, improving connectivity and reducing travel times through new stations at 106th Street and 116th Street on Second Avenue, as well as a terminal station at 125th Street and Lexington Avenue, which will serve as a major transfer point to the 4/5/6 lines and the Metro-North network.
This contract builds on Phase I of the Second Avenue Subway project, which extended service from 63rd Street to 96th Street and has been operational since 2017, continuing the line’s northward extension to 125th Street. Skanska, in a joint venture with J.F. Shea Construction and Schiavone Construction, previously delivered this first phase.
Once completed, the Second Avenue Subway will create a double-track line from 125th Street to Lower Manhattan, with connections to West Midtown and Brooklyn, expanding transit access for residents, workers, and visitors on the East Side, while reducing congestion on the nearly 100-year-old Lexington Avenue line.
