Dock Bridge is a pair of vertical lift bridges crossing the Passaic River at Newark, Essex County and Harrison, Hudson County, New Jersey, United States, used exclusively for railroad traffic. It is the seventh crossing from the river's mouth at Newark Bay and is 5.0 miles (8.0 km) upstream from it. Also known as the Amtrak Dock Vertical Lift, it carries Amtrak, NJ Transit, and PATH trains. It is listed on the state and federal registers of historic places.

The Gateway Program is the planned phased expansion and renovation of the Northeast Corridor (NEC) rail line between Newark, New Jersey, and New York City along right-of-way between Newark Penn Station and New York Penn Station. The project is to build new rail bridges in the New Jersey Meadowlands and new tunnels under Bergen Hill and the Hudson River, rehabilitate the existing 1910 tunnel, and construct a new terminal annex.
