History

SR 173 was commissioned in 1923, originally routed from SR 19. northeast of Louisville, to SR 19, south of Beloit. In 1927 the route was rerouted onto the route of previous SR 19, through Alliance. The route was extended west to its current western terminus, at SR 44, in 1937. Between 1969 and 1971, SR 173 was rerouted concurrent with US 62 from west of Alliance to Salem. In 1976 US 62 in Salem was rerouted to bypass the city and SR 173 remained on the old route of US 62.
