The New Jersey Transit Corporation (NJ TRANSIT) in cooperation with the Gateway Program Development Corporation (GDC), the Port Authority of New York and New Jersey (PANYNJ), and the National Railroad Passenger Corporation (Amtrak), propose the construction of a new, two-track fixed structure railroad bridge across the Hackensack River in Hudson County, New Jersey, along the Northeast Corridor (NEC). The existing moveable swing span bridge has only 23 feet of vertical clearance above the mean high water level and must pivot open to allow maritime traffic to pass through, closing the bridge to rail traffic and interrupting operations on the NEC for both Amtrak and NJ TRANSIT.
