The Hudson Tunnel Project

The Hudson Tunnel Project involves construction of a new Hudson River rail tunnel serving New York Penn Station and the rehabilitation of the existing Sandy-damaged North River Tunnel.

The high level of traffic in the existing North River Tunnel — approximately 450 trains per weekday — means that without this project, taking one of the North River Tunnel tubes out of service for necessary repairs would severely reduce rail service because the remaining tube would have to accommodate two-way traffic. This very significant reduction in capacity would have a devastating effect on New York and New Jersey commuters who cross the Hudson on a daily basis, Amtrak passengers, and the regional and national economies.

Pre-COVID, approximately 200,000 daily passenger trips took place in the existing North River Tunnel, which was built by the Pennsylvania Railroad and completed in 1910. The tunnel consists of two, single-track, electrified tubes, which serve as the only passenger rail connections between Manhattan and New Jersey and the rest of the Northeast Corridor. In October 2012 the tunnel was inundated with millions of gallons of salt water during Super Storm Sandy, leaving behind corrosive chemicals which continue to degrade the concrete tunnel liner, benchwalls and other systems that support Amtrak and NJ TRANSIT train operations.

An Environmental Impact Statement (EIS) for the project is currently being prepared by the Federal Railroad Administration, Port Authority of NY & NJ and NJ TRANSIT. Amtrak, the owner of the existing North River Tunnel, is leading engineering design in coordination with the project partners. The Draft Environmental Impact Statement is available, released in July 2017.

Full funding for the environmental planning work and preliminary engineering of the Hudson Tunnel Project has been provided by Amtrak, the Port Authority, and NJ TRANSIT totaling $86.5 million.
