The Historic Cornish-Windsor Covered Bridge is an impressive covered bridge. It is the longest covered bridge in the US at 460 feet long! It was originally constructed in 1866 and is a Town Lattice truss. The bridge crosses the Connecticut River and connects the states of New Hampshire and Vermont together. Unlike many covered bridges, this one has two lanes for traffic. The best views of the bridge are on the NH side. There is a parking area on the NH side for viewing the bridge. There are also parking areas along Route 12A on the NH side if you want to see the bridge from a further distance. From the Vermont side the view is narrow and it is hard to see the whole bridge. The bridge has a lot of traffic and it is not a great idea to try to walk across the bridge. If you’re interested in seeing more covered bridges in the area there are some on the NH side that are close to this bridge. The area around the bridge has a lot to do as the August Saint-Gaudens National Park is on the NH side of the bridge and the Museum of American Precision is on the Vermont side. Overall, this bridge is one of the most impressive covered bridges in the US.
Jul 29, 2026 · Google ReviewState of New Hampshire Covered Bridge No. 20. The Cornish-Windsor Bridge was constructed by James F. Tasker of Cornish and Bela J. Fletcher of Claremont in 1866. The bridge was framed in a nearby meadow and reassembled over the river. Tasker and Fletcher used a modified version of the Town lattice truss, using square timbers instead of planks to form the lattice, and they notched and bolted the lattice members together instead of using traditional trunnels. According to covered bridge historian Joseph Conwill, notched timber lattice bridges were not commonplace, and the Cornish-Windsor Bridge is the only surviving example.

Such a beautiful bridge on a beautiful sunny day. My recently late mother loved covered bridges, and I took this as a sign from her. Naturally I pulled over to take some pics. Thanks mom for leading me down this road 🙂
May 26, 2026 · Google ReviewBeautiful, well kept historic site at the NH-VT State line. There is an area to park to the left, facing the bridge on the NH side. Easily could park 3-5 average cars there. We parked, got out and looked at the bridge, and took pictures at the NH welcome sign.
Jul 3, 2025 · Google ReviewLocated at the New Hampshire-Vermont state line, the historic Cornish-Windsor Covered Bridge is an impressive landmark. It is highly recommended for visitors to experience the bridge by driving through it. The structure is frequently used by local traffic, often at high speeds, so walking across the bridge is not advised. For those wishing to stop and view the bridge, there is a parking area on the New Hampshire side, which can accommodate approx 3 vehicles.
