The Town lattice truss bridge was built in 1864-1865 and added to the National Register of Historic Places in 1974.

The Cedar Swamp Covered Bridge stood in a rural area of southeastern Cornwall and western Salisbury, connecting Cornwall's Swamp Road with Salisbury's Creek Road.

The bridge was a Town lattice truss structure, built as a single span 153.5 feet (46.8 m) long.

Its exterior was finished in vertical board siding, which extended a short way on the inside of each portal.

The portal openings were shaped as elliptical arches, and it was capped by a metal roof.
