The West Dummerston Covered Bridge is a historic covered bridge spanning the West River in Dummerston, Vermont, between Vermont Route 30 and Camp Arden Road. Built in 1872, it is at 280feet the longest covered bridge entirely within the state of Vermont. It was listed on the National Register of Historic Places in 1973.
The West Dummerston Covered Bridge is located in west-central Dummerston, a short way north of the village of West Dummerston. It spans the West River in a roughly east–west direction, and is mounted on stone abutments and a central stone pier. The bridge consists of two spans, each supported by Town lattice trusses, and has a total structure length of 280feet. The sides of the bridge are finished in flush vertical boards, and the ends are sheathed in wooden clapboards. The roof is of corrugated metal, laid over an older wooden shingle roof. The side walls have diamond-shaped openings cut in them to admit additional light.[1]
The bridge was built in 1872 by master builder Caleb Lamson, and is the only known surviving example of his work in Windham County. It is the longest covered bridge entirely within the state: the Scott Covered Bridge in Townshend is 277feet long, and the Cornish–Windsor Covered Bridge (spanning the Connecticut River into New Hampshire) is the nation's longest, at 449feet.
