The Slate Covered Bridge is a wooden covered bridge which carries the Westport Village Road (formerly New Hampshire Route 10) over the Ashuelot River in Westport, a village of Swanzey, New Hampshire. The bridge was built in 2001, as a replacement for an 1862 bridge that was destroyed by arson fire in 1993.
The 1862 bridge was a single span Town lattice truss, with a span of 122 feet (37 m) and a roadway width of 17 feet (5.2 m). Its name derives from a family that lived nearby at the time of its construction. It rested on abutments of split granite, and was covered with a tin roof. Its sides were fully sheathed, and it had numerous repairs and parts replaced. It was listed on the National Register of Historic Places in 1978.
