The West Swanzey Bridge is located east of N.H. Route 10 on Main Street over the Ashuelot River in
West Swanzey. The bridge connects two built-up areas of the town.
The bridge was constructed by Zadoc Taft and is also known as the Thompson Bridge. In 1976, a new concrete and steel bridge was built nearby to carry heavy vehicles at a cost of $376,914. The bridge has been closed to vehicular traffic since the fall of 1990 after a report by state inspectors indicated the bridge was unsafe.
The West Swanzey Bridge is listed on the National Register of Historic Places.
