The Ashtabula lift bridge (also known as the West Fifth Street bridge) is a Strauss bascule bridge that carries Ohio State Route 531 over the Ashtabula River in the harbor of Ashtabula, Ohio. Besides its importance as a major transportation route in Ashtabula, the bridge occupies a crucial location in the city's built environment; the Ashtabula Harbour Commercial District terminates at the bridge's western end.
