Cornish-Windsor Covered Bridge

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.

While the Old Blenheim Bridge and Bridgeport Covered Bridge have 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 still has the longest single covered span to carry automobile traffic (Blenheim and Bridgeport are pedestrian only).


The bridge is approximately 449 feet (137 m) long and 24 feet (7.3 m) wide. It has a Town lattice type truss. The bridge was originally built in 1866, and rebuilt in 1988. 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 high-water mark of the river. When one drives onto the bridge from the Windsor side of the river they are immediately in New Hampshire. The name is a point of contention among locals since many Cornish inhabitants refer to the bridge as the 'Cornish Covered Bridge' (minus 'Windsor') since, they argue, the bridge belongs to Cornish and not Windsor.
