NJ TRANSIT and Amtrak are replacing the century-old Portal Bridge over the Hackensack River in New Jersey with a higher bridge that will not have to open and close for river traffic.
The existing 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 River – a critical link in the congested territory between Newark, New Jersey and Penn Station, New York. 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.
A two-track replacement bridge – Portal North – will replace this outdated relic with a modern, high-level fixed span that does not open or close, eliminating the movable components and risk of malfunction. The new bridge will rise 50-feet over the river and, including the approaches, span nearly 2.5 miles of the Northeast Corridor. Portal North Bridge is an important element of the broader Gateway Program that will eventually double rail capacity between Newark and New York.
In October 2021, the NJ TRANSIT Board of Directors approved a contract with Skanska/Traylor Bros Joint Venture for the construction of the new Portal North Bridge. The $1,559,993,000 construction contract for the project, the largest award in NJ TRANSIT’s history, includes construction of retaining walls, deep foundations, concrete piers, structural steel bridge spans, rail systems, demolition of the existing bridge, and related incidental works. Once construction begins, the construction contract is anticipated to take approximately five and a half years to complete.
The project is being funded by the US Department of Transportation, Transportation Trust Fund, New Jersey Turnpike Authority and Amtrak. In January 2021, Governor Murphy announced the signing of a Full Funding Grant Agreement which secured $766.5 million in Federal Transit Administration funding to support the project’s final design and construction.
Soman Stone was contracted to manufacture and provide articulated concrete mattresses to provide cable protection and scour protection for a new power transmission cable that will cross the Hackensack River. Roman Stone provided 20’ x 8’ x 12” mattresses and a submersible installation frame to be used to protect the cable once installed.
