A joint venture of AECOM and STV has also been awarded a management contract to support the project through its final design and construction phases.
This project will replace the current bridges with four-track structures, increasing capacity, and speed along this rail segment.
Constructed in 1907, the Sawtooth Bridges are a vital component of the NEC, supporting more than 400 daily trains operated by Amtrak, NJ TRANSIT, PATH, and Conrail freight trains.
The bridges’ age and structural deficiencies currently limit train speeds to 60mph, causing bottlenecks that affect both intercity and commuter rail services. A 2013 condition survey confirmed the need for new bridges.
The replacement project will double the track capacity from two to four and restore maximum speeds to 90mph.
