en.Wedoany.com Reported - The Massachusetts Department of Transportation (MassDOT) recently announced the official launch of the nearly $2.5 billion Sagamore Bridge replacement project and is soliciting Letters of Interest from contractors. This bridge is one of two key highway bridges connecting Cape Cod to the rest of Massachusetts.
This procurement process is the first step in the "Cape Cod Bridges Program" initiative, which aims to replace the Sagamore Bridge and the Bourne Bridge to its west. Both bridges were constructed in 1935 and together carry approximately 38 million vehicles annually, far exceeding their original design capacity of 1 million vehicles per year, and have been classified as functionally obsolete.
MassDOT has established a clear timeline for the project. The deadline for submitting initial Letters of Interest is noon on May 27, 2026. Subsequently, the department will issue a Request for Qualifications, with a Request for Proposals expected to be released this summer. Louisa Paiewonsky, Executive Director of MassDOT's Office of Major Project Delivery, stated that this major bridge project is moving forward rapidly.
Funding for the Sagamore Bridge replacement project is largely secured. Sources include a $993 million grant from the Federal Bridge Investment Program, $372 million from the Federal Mega Project Grant Program, $350 million from the U.S. Army Corps of Engineers, and approximately $750 million in state funding.
According to the plan, the final design-build contract will require the contractor to construct a more efficiently configured interchange, which is key to meeting modern transportation needs. The new bridge will feature shoulders and merge lanes to optimize traffic flow. The bridge structure will utilize an arch design, specifically a network tied-arch type, in response to community input. MassDOT also encourages contractors to propose alternative technical concepts in their proposals that could reduce costs or accelerate the schedule.
In addition to the main bridge structure, the contractor will also be responsible for constructing portions of a new, approximately 9-mile network of bicycle and pedestrian paths in the area after the bridge is completed. Due to the project's land requirements, 13 residential properties and some commercial properties in the Cape Cod area will be acquired through eminent domain. MassDOT aims to complete all real estate acquisitions by fall 2027.
Construction of the entire bridge project is expected to be substantially completed by spring 2037. The new bridge, once built, will be owned and operated by the state, while the existing old bridge falls under the jurisdiction of the U.S. Army Corps of Engineers. Due to its scale and regional importance, the project has garnered widespread attention within the U.S. engineering community.
