description Bourne Bridge Overview
The Bourne Bridge is a highway bridge across the Cape Cod Canal in Massachusetts. Built in the 1930s and opened in 1935, it is a steel Warren through-truss structure with a central arch-truss span designed to provide clearance for vessels using the canal. The bridge carries Route 28 between the mainland town of Bourne and Cape Cod and is one of the two main road crossings of the canal, alongside the Sagamore Bridge.
help Bourne Bridge FAQ
Where is the Bourne Bridge and what route does it carry?
It carries Route 28 across the Cape Cod Canal in Massachusetts, connecting the mainland to Cape Cod at the town of Bourne. Its near-twin, the Sagamore Bridge, crosses the canal a few miles east.
When was the Bourne Bridge built?
It was built in the 1930s and opened in 1935, replacing earlier bridges from the canal's original 1914 construction. Structurally it is a steel Warren through-truss with a central arch-truss span for vessel clearance.
Why is the Bourne Bridge so congested in summer?
It is one of only two road crossings onto Cape Cod, so weekend vacation traffic funnels into its lanes. The US Army Corps of Engineers, which operates the canal and both bridges, has studied the bottleneck for years.
Are there plans to replace the Bourne Bridge?
Yes — a Cape Cod Bridges replacement program has been advancing since the 2010s and 2020s to build new spans alongside the aging Bourne and Sagamore bridges. Disputes over the multi-billion-dollar cost have repeatedly slowed the project.
