The project scope covers the design and construction of new station structural shells between 105th Street and 110th Street to accommodate the future 106th Street Station.
The works include construction of structural tie-ins to existing tunnels, support of excavation and earthwork activities, installing roadway decking to maintain existing traffic, construction of at- and below-grade structures for two station entrances, and extensive utility support and reconstruction work.
The contract, awarded by the Metropolitan Transportation Authority, is valued at US$1bn (€860m).
Phase 2 builds on the first phase of the Second Avenue Subway project, which extended service from 63rd Street to 96th Street and has been in operation since 2017, and continues the northward expansion of the Q Line to 125th Street in Harlem.
Work is expected to be completed in the third quarter of 2030.
