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. It was constructed in 1925 by a Cleveland firm, Wendell P. Brown, for $179,000. The lifting action depends on electric motors and a massive concrete counterweight. It is one of only two of its type that remain in service in the state of Ohio, and the only one extant in the state highway system. In 1985 it was listed on the National Register of Historic Places. It was restored in 1986, and was also closed from March 2008 through May 2009, for repairs and repainting. Besides its importance as a major transportation route in Ashtabula, it occupies a crucial location in the city's built environment; the Ashtabula Harbour Commercial District terminates at the bridge's western end.
