The Cornish–Windsor Covered Bridge is a covered bridge that spans the Connecticut River between Cornish, New Hampshire and Windsor, Vermont. It was the longest covered bridge still standing in the United States until the Smolen–Gulf Bridge opened in Ohio in 2008.[3]

While the Old Blenheim Bridge had and Bridgeport Covered Bridge has longer clear spans, and the Smolen–Gulf Bridge is longer overall, with a longest single span of 204 feet (62 m), the Cornish–Windsor Bridge is still the longest wooden covered bridge and has the longest single covered span to carry automobile traffic (Blenheim was and Bridgeport is pedestrian only).


There were three bridges previously built on this site—one each in 1796, 1824 and 1828.[4] The 1824 and 1828 spans were constructed and operated by a group of businessmen which included Allen Wardner.[5]

The current bridge was originally built in 1866, and rebuilt in 1988. The bridge is approximately 449 feet (137 m) long and 24 feet (7.3 m) wide. It has a Town lattice type truss. It was designated a National Civil Engineering Landmark by the American Society of Civil Engineers (ASCE) in 1970.

The bridge is owned and maintained by the State of New Hampshire, and though often associated with Windsor, is in fact part of the town of Cornish, since the defined boundary between New Hampshire and Vermont is at the western mean low-water mark of the river. When one drives onto the bridge from the Windsor side of the river one is immediately in New Hampshire.[6]
