The Massachusetts Department of Transportation (MassDOT) announced on March 26, 2026, a new milestone in the Cape Cod Bridges Program with the publication of a request for Letters of Interest from qualified design and construction firms for the Sagamore Bridge replacement project.
MassDOT will then issue a request for Qualifications (RFQ) followed by a request for Proposals (RFP), resulting in the selection of a design-build team and issuance of a Notice to Proceed by late 2027. Construction of the new Sagamore Bridge will start in the winter of 2027-2028.
The launch of the procurement process is a major step toward replacement of the Sagamore Bridge and a significant step forward in ensuring safe, reliable travel between Cape Cod and mainland Massachusetts, according to MassDOT. Through the procurement process, MassDOT will continue to provide public updates about the project's progress.
"Delivering essential transportation projects in a timely manner, on time and on budget is one way we can best serve the communities and residents that rely on a sound transportation system," said Phil Eng, interim transportation secretary and MBTA general manager. "Engaging with industry and potential bidders demonstrates our commitment towards replacing the Sagamore Bridge. The Healey-Driscoll administration is investing in transportation needs that benefit Cape Cod's 230,000 year-round residents and more than five million visitors, create thousands of jobs supporting local businesses and serve as an economic lifeline for those who work in the region."
"The Sagamore Bridge and Bourne Bridge replacement are some of the most important infrastructure initiatives in the country, and today's announcement marks a major milestone in advancing the Healey–Driscoll Administration's efforts to get this project done," said Jonathan Gulliver, undersecretary and state highway administrator. "By issuing this Letter of Interest, we are setting the stage for a competitive procurement that will bring forward innovative solutions and help deliver a safer, more reliable connection to Cape Cod."
The Cape Cod Bridges project, led by MassDOT in partnership with the U.S. Army Corps of Engineers and Federal Highway Administration, will provide new crossings over the Cape Cod Canal to replace the federally owned, 90 year-old Sagamore and Bourne Bridges, the only roadway connections between Cape Cod and the Massachusetts Mainland.
The Sagamore Bridge replacement will be the first phase of the project and also will include roadway realignments of Route 6 and Route 3, reconstruction of local roadway connections and new bicycle and pedestrian pathways on the bridges and along the canal. MassDOT has applied for more than $1 billion in federal grant funds for replacement of the Bourne Bridge.
The scope of work also includes bridge and roadway construction, traffic management to maintain travel during construction, stormwater improvements, environmental permitting and compliance and coordination with utilities and stakeholders. The project is currently undergoing environmental review in accordance with state and federal requirements.
