MTA Approves $1.97 Billion Tunneling Contract to Extend Second Avenue Subway

Why does this matter? This extension will significantly improve transportation access for East Harlem residents, connecting them to the rest of the city and reducing their reliance on other transit options. The project also incorporates cost-saving measures and innovative technology to ensure efficient construction.

Phase 2 of the Second Avenue Subway involves significant tunneling work and the construction of three new stations. The contract includes converting an existing 2,500-foot tunnel into a station box, boring an 8,400-foot tunnel to Malcolm X Boulevard, and excavating shafts for ancillary buildings. The MTA is using a variable-density tunnel boring machine that can handle both soft soil and hard rock, streamlining the excavation process.

The MTA has implemented several cost-cutting measures for Phase 2, including reducing station sizes, reusing existing tunnel segments, and applying value engineering proposals. These efforts have resulted in substantial savings, making the project more financially feasible. The project also includes a 20% local hiring goal and partnerships with City College of New York, providing economic opportunities for the community.

Utilities are currently being relocated to make way for the 106th station, and the next contract will focus on fitting out the interiors of the new stations and systems. Once completed, the Second Avenue Subway is expected to carry about 300,000 passengers a day, combined with Phase 1.
