Colonel Alexander Scammell Memorial Bridge, Spanning Bellamy River at U.S. Route 4, Dover, Strafford County, NH

Significance: The bridge is a representative example of a single leaf bascule lift bridge with a vertical overhead counterweight. It is the oldest of the state's three remaining bascule bridges and is the only one in which the counterweight is visible. Construction of the bridge in 1935 was part of a larger Public Works Administration funded project to restore a direct route from the seacoast to Concord through Durham.
