63rd Street Connector

Queens, New York, United States

Client: Metropolitan Transportation Authority - New York City Transit

Parsons Brinckerhoff Role: Design

63rd Street Connector
Parsons Brinckerhoff in joint venture designed a tunnel to connect the existing 63rd Street Tunnel under the East River to a subway line in Queens, which allowed for subway service between Queens and Manhattan via the 63rd Street Tunnel, which Parsons Brinckerhoff had designed 20 years earlier.

The Parsons Brinckerhoff joint venture designed a 1,700-foot- (518-meter-) long connecting tunnel under an existing subway line amid some of the most complex subterranean infrastructure in New York City. In order not to disrupt existing subway service, work on the tunnel was performed largely on weekends and off hours, and took seven years to complete, opening in December 2001. The highly complex project demanded a broad range of structural engineering skills and also included two ventilation buildings and modifications to the existing subway tunnel and six subway stations in Queens.

The F train now uses the tunnel to provide service between Manhattan and Queens, with a stop at Roosevelt Island.

Currently, Parsons Brinckerhoff is at work on another project—East Side Access—that will link the Long Island Rail Road to the 63rd Street Tunnel, allowing the tunnel to be used for both subway and Long Island Rail Road trains as originally envisioned in the 1960s.
