The Port Authority of New York and New Jersey (PANYNJ), the Gateway Development Commission (GDC), New Jersey Transit Corporation (NJ TRANSIT) and the National Railroad Passenger Corporation (Amtrak), propose the construction of a new two-track heavy rail tunnel along the Northeast Corridor from the Bergen Palisades in New Jersey to Manhattan that will directly serve Penn Station New York. The Project consists of three major elements: the Hudson Yards right-of-way preservation, a new Hudson Tunnel, and the rehabilitation and modernization of the existing North River tunnel.
