The Slaughter House Covered Bridge in Northfield, Vermont, carries Slaughterhouse Road over the Dog River near Northfield Falls and is one of five surviving nineteenth-century covered bridges in the town, a notably high number for Vermont. Built in 1872, it is a single-span Queen post truss on dry-laid stone abutments, measuring 59.5 feet long and 14.5 feet wide for one lane of traffic. Its wooden exterior has vertical board siding and reverse-ogee gable ends. The road once led to the slaughterhouse that gave the bridge its name, and the structure was listed on the National Register of Historic Places in 1974.
