History
SR 245 was first designated in 1962. The original routing of the highway consisted of the same route as today. Prior to June 1963, SR 245 was signed as SR 275. The route was renumbered at that time due to Ohio renumbering state highways sharing the same number as Interstate highways; Interstate 275 forced the renumbering of SR 275.
