Client: Metropolitan Transportation Authority (New York)

  • New 8.5 mile, 16 station subway line on Manhattan's East Side.
  • First new subway in New York in nearly 80 years.
  • Four-phase project extends through 2020.
The Second Avenue Subway will run the entire length of Manhattan, connecting with an existing East Side subway line and a commuter railroad at 125th Street to the north, and running south to the Financial District at the tip of the island.

The twin-track line will include sixteen new underground stations and will be built using both bored tunnels and cut-and-cover excavation. The project will occur below and amid some of the most congested urban infrastructure in the world.

Arup, as part of a joint venture, is providing full design and engineering services on the project.

The new line will reduce overcrowding and delays on Manhattan's Lexington Avenue line and make mass transit more accessible to people living on Manhattan's far East Side.

The first phase of the project will create a new service along Second Avenue, with three new stations and new connections to the 'Lex', alleviating congestion on one of the existing line's most overburdened segments.

New Yorkers first approved a subway below Second Avenue in 1929, but work on the project has been delayed, initially by the Great Depression and World War II, and subsequently for economic reasons. The city took over and consolidated the city-wide subway service in 1940 and took the old elevated Second Avenue line out of service in 1942.
