Cornish-Windsor Covered Bridge

The Cornish-Windsor Covered Bridge is a two-span, timber Town lattice-truss bridge crossing the Connecticut River between Cornish, New Hampshire and Windsor, Vermont. The current structure was built in 1866 by Bela Jenks Fletcher of Claremont and James Frederick Tasker of Cornish at a cost of about $9,000, replacing three earlier bridges on the site (1796, 1824, and 1828). At approximately 449 feet long and 24 feet wide, it was the longest covered bridge still standing in the United States until the Smolen-Gulf Bridge opened in Ohio in 2008, and it remains the longest wooden covered bridge and the longest single-span covered bridge carrying automobile traffic.

It operated as a toll bridge from 1866 until 1943, earning a reputation as a "kissing bridge." The state of New Hampshire purchased it in 1936. In 1970 the American Society of Civil Engineers designated it a National Historic Civil Engineering Landmark, and it was listed on the National Register of Historic Places in 1976. A major rehabilitation followed in 1988. Because the New Hampshire-Vermont boundary runs along the western low-water mark of the Connecticut River, nearly the entire bridge lies in New Hampshire.
