NJT Portal Bridge North Project

The existing, 111-year-old Portal Bridge was built by the Pennsylvania Railroad and entered revenue service in November 1910. Prior to the COVID-19 pandemic, the bridge carried more than 450 daily Amtrak and NJ TRANSIT trains and 200,000 daily passengers over the Hackensack. This two-track, moveable swing span is a major bottleneck and source of delays, particularly when the aging bridge malfunctions during opening and closing for maritime traffic.
