The Carleton Bridge is a historic wooden covered bridge that carries Carleton Road over the South Branch Ashuelot River in East Swanzey, New Hampshire. The bridge was built in 1869 on a site that is believed to have had a bridge since 1789. It is believed to be the only example of a Queenspost truss bridge in southern New Hampshire. This truss method is quite old, and is based on techniques used for building large structures such as churches and barns. The bridge measures 67' 3", with a span of 60'3". It is 16'6" wide with a road width of 12'4".
