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 Massachusetts Route 25, which ends at the interchange with US 6/Route 28 just north of the bridge, and provides freeway connections from Interstate 495 and Interstate 195.
There is a sidewalk for pedestrian and bicycle access on the west side of the bridge, the only legal way to walk or pedal onto the part of Cape Cod beyond the canal.
During relatively high winds of 70MPH or above due to bad weather, bridges to the Cape are sometimes closed for safety.
The bridge, along with its sibling, the Sagamore Bridge, was 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. Both bridges carry four lanes of traffic over a 616-foot (188 m) main span, with a 135-foot (41 m) ship clearance, and opened on June 22, 1935. Due to the topography of the land, however, the approaches to the main span of the Bourne Bridge are considerably longer than those of the Sagamore Bridge.
The bridge replaces an earlier 1911 drawbridge; the current structure was built to accommodate the widening of the canal. Like the old Sagamore Bridge, the original drawbridge's approaches are still accessible.
The bridge commences at a major rotary, this one on the east (Cape Cod) end. On the mainland side, New York Central Tugboat 16 sat on dry land at the approach to the bridge from the rotary from 1982 to 2006, serving as a local attraction.
