The Metropolitan Transportation Authority plans to award a $1.97 billion contract for tunnel boring and construction of two new subway stations in Harlem. This initiative is part of Phase 2 of the Second Avenue Subway project, which aims to extend the line north and is expected to serve 110,000 daily riders. The project includes converting an existing tunnel and creating new tunnels to accommodate new stations. Advanced technology in tunneling will facilitate the construction while reducing costs. The completed subway line will cater to approximately 300,000 riders daily when fully operational.
The Metropolitan Transportation Authority is set to approve a $1.97 billion contract to bore tunnels and start construction on two new Harlem subway stations.
Phase 2 will add three new Q line stations at 106th, 116th, and 125th streets, serving an estimated 110,000 daily riders.
The tunneling will be done with a 1.5 million-pound German-made variable-density tunnel boring machine that can switch between soft soil and hard rock.
Officials state that the combination of Phase 1 and Phase 2 is expected to carry about 300,000 passengers a day.
