Notes
The bridge spans the Connecticut River to connect the towns of Cornish, New Hampshire and Windsor, Vermont. The western bank of the Connecticut River is considered to be the state line between the two states and therefore, the bridge is considered to be a New Hampshire bridge. The bridge is the longest wooden covered bridge in the United States as well as the longest two-span covered bridge existing in the world
