The U.S. Army Corps of Engineers (USACE) is partnering with Massachusetts Department of Transportation (MassDOT) and the Federal Highway Administration (FHWA) to replace the federally-owned and operated Bourne and Sagamore bridges as part of the Cape Cod Bridges Program, Bourne, Massachusetts. Both bridges, constructed between 1933 and 1935 and determined eligible for listing in the National Register of Historic Places on March 6, 1991, are subject to "bridge marketing" requirements under Section 4(f) of the Department of Transportation Act of 1966 (P.L. 89-670, 80 Stat. 931), as codified in 23 U.S.C. § 138 and 49 U.S.C. § 303. Consequently, USACE is making these historic structures available for adoption to any public or private entity interested in their removal, relocation, and repurposing for alternative use. Interested parties should visit the MassDOT’s Cape Cod Bridges Program website at https://www.mass.gov/cape-cod-bridges-program for further information.
The Sagamore Bridge is a three‑span steel riveted continuous Warren through‑truss that carries U.S. Route 6 over the Cape Cod Canal, Sandwich Road, and the Massachusetts Coastal Railroad. The Sagamore Bridge has total length of 1,833 feet, including its two concrete abutment spans, and a minimum clearance of 135 feet above mean high water (MHW) of Cape Cod Canal.
The Bourne Bridge is a seven-span steel riveted continuous Warren through truss that carries Massachusetts Route 28 over the Cape Cod Canal, Sandwich Road, and the Massachusetts Coastal Railroad. The Bourne Bridge has a total length of 2,684 feet, including its two concrete abutment spans, and a minimum clearance of 135 feet above MHW of Cape Cod Canal.
The USACE is accepting proposals for the relocation and alternative use of either or both of the bridges until June 26, 2026. Because the bridges were constructed in the 1930s, paint systems on both bridges contain lead and other possible constituents requiring controlled removal and containment that may result in additional cost to the adopter. Interested adopters must submit a relocation plan detailing the bridge’s proposed use, location, schedule for relocation, and the available resources to ensure continued maintenance of these structures. Interested adopters must demonstrate the ability to comply with all applicable environmental regulations, including requirements for hazardous materials handling, waste disposal, and location specific permitting.
