As part of the Massachusetts Department of Transportation’s (MassDOT) Accelerated Bridge Program, the Fore River Bridge was identified as one of five high-priority “mega projects” requiring replacement. The original 1936 bascule bridge, after decades of wear, was replaced in 2004 with a temporary structure that offered only a short-term solution. To restore a reliable, resilient connection between Quincy and Weymouth, MassDOT advanced a full replacement effort for a modern vertical-lift bridge capable of meeting long-term operational needs.
What challenges did STV address?
The aging temporary bridge lacked the structural integrity, operational efficiency, and navigational clearance necessary for marine and vehicular traffic. The project required developing a durable, 75-year structure while minimizing impacts to commuters and maintaining continuous access along this vital corridor. Environmental permitting, public outreach and evaluation of multiple replacement options added further complexity to the effort.
What solutions did STV deliver?
As part of the design-build team, STV provided comprehensive engineering and construction support services. The firm helped evaluate feasible replacement concepts and advanced the full design of the new 2,640‑foot vertical lift bridge. STV delivered environmental assessments, public outreach support, design-build procurement documentation and construction-phase services. With an increased vertical clearance of more than 220 feet when open, the lift span reduces congestion and significantly improves both marine and roadway operations.
How does this project benefit the region?
The new Fore River Bridge enhances travel reliability for thousands of daily commuters, supports commercial maritime activity and strengthens long‑term regional mobility. Its durable and efficient design reduces maintenance needs and provides safe, predictable crossings between Quincy and Weymouth for decades to come.
