Amtrak has selected the Flatiron/Herzog Joint Venture as the Construction Manager at Risk (CMAR) contractor for construction of two new bridges and associated track work, along with two supporting contracts that will advance replacement of the existing 117-year-old Susquehanna River Rail Bridge.

Today’s announcement follows a year-long competitive procurement process that began in 2022 and was supplemented by extensive industry outreach, including an “Industry Day” that helped build interest in this key Northeast Corridor (NEC) project.

The Federal Railroad Administration (FRA) recently announced up to $2.08 billion in grant funding to support final design and construction for this project, along with 24 other projects totaling more than $16.4 billion of federal investment across the NEC. Two newly constructed two-track fixed bridges will replace the existing two-track moveable bridge, along with overhead power, signal, safety and security system modernization that will improve railroad efficiency on the NEC.

As the longest moveable bridge on the NEC, the Susquehanna River Rail Bridge is used by Amtrak, Maryland Area Regional Commuter (MARC) rail and Norfolk Southern to support more than 110 passenger and freight trains daily. Currently, crossing the bridge requires trains to slow to a speed of 90 mph, resulting in capacity and reliability constraints.

Construction of the new bridges is being delivered through the CMAR delivery method. This innovative approach is the second CMAR contract Amtrak has awarded in recent months, following the first major construction contract for the Frederick Douglass Tunnel Program.

Amtrak has also awarded two other contracts that will help advance the Susquehanna River Rail Bridge Replacement Program. This includes a project and construction management contract awarded to an AECOM-led team in order to support completion of the final design and perform construction management for the bridge construction phase. This team will be fully integrated with the Flatiron/Herzog Joint Venture.

Fay Construction has also been selected to demolish and remove 10 remnant piers, which remain from an 1866 railroad bridge that was located just east of the existing bridge. The remnant pier work will begin in early 2024 and last approximately one year.

Final design work is underway for the two new bridges, which will be built in a phased approach; 100% design completion is expected by the end of 2024 and construction is scheduled to begin in 2025.
