East River Tunnel
2.5 miles
Construction Manager: Skanska USA
The East River Tunnel project is a rehabilitation of the entire 2.5-mile-long East River Tunnel system that connects New York Penn Station to the Sunnyside Yard in Queens. The project involves rehabilitating all four tubes of the tunnel, with a focus on rebuilding each tube one at a time over a roughly 13-month period for each tube's complete shutdown. The work will repair damage caused by Hurricane Sandy and update the century-old system for another 100 years of service. The project is primarily funded by the Infrastructure Investment & Jobs Act grant awarded by the Federal Rail Administration in 2023. The scope of work includes spot repairs and patching of the concrete tunnel liner, reconstruction of the bench walls with a modern high-low configuration, conversion from ballasted track to a modern direct fixation track system with integrated drainage, new fire and smoke detection systems, and replacing and modernizing signal, traction power, standpipe and drainage systems.
