the American bridge on Cape Cod

The Bourne Bridge in Bourne, Massachusetts, carries Route 28 across the Cape Cod Canal, connecting Cape Cod with the rest of Massachusetts. It won the American Institute of Steel Construction's Class "A" Award of Merit as the "Most Beautiful Steel Bridge" in 1934. Most traffic approaching from the west follows Route 25 which ends at the interchange with US 6 and Route 28 just north of the bridge. The highway provides freeway connections from Interstate 495 and Interstate 195.

The bridge and its sibling the Sagamore Bridge were constructed beginning in 1933 by the Public Works Administration for the United States Army Corps of Engineers, which operates both the bridges and the canal. Each bridge carries four lanes of traffic over a 616 foot (188 m) main span, with a 135 foot (41 m) ship clearance. Construction ended in early 1935 and the bridge opened on June 22, 1935. The approaches to the main span of the Bourne Bridge are considerably longer than those of the Sagamore Bridge due to the topography of the land. The bridge replaced an earlier 1911 bascule bridge (drawbridge), the Bourne Highway Bridge, the original approaches of which are still accessible. The current structure was built to accommodate the widening of the canal. The bridge commences at a major rotary on the Cape Cod end.

Between 1967 and 1977, 36 persons were recorded as having died by suicide from the Bourne and Sagamore bridges, and another 24 had attempted but either survived or were apprehended.

In October 2019, the Army Corps of Engineers recommended replacing the bridge with a wider bridge with four travel lanes, one auxiliary lane in each direction, bike and pedestrian paths, shoulders, and a median. The recommendation said that replacement was more cost effective than upgrading the existing bridge in order to reduce long summertime backups. The Massachusetts DOT is following up on the 2019 study about the future of the bridge along with the Sagamore Bridge. The 2019 study concluded that improvements were needed to connectivity across the canal. The Cape Cod Bridges program is currently taking public input into the multi phased project and have unveiled different design types for feedback.

There is a 6 feet (2 m) sidewalk for pedestrian and bicycle access on the west side of the bridge. The sidewalk is slightly raised, but there is no fence or barrier between it and car traffic, and cyclists are recommended to walk their bicycle. The bridge road is plowed in winter, although the sidewalk is sometimes unplowed and unpassable. Bridges to the Cape are sometimes closed for safety during high winds.
