History

SR 305 was applied in 1932. The highway was originally a very short route that existed only along its present easternmost stretch between its junction with SR 7 and its connection with PA 718 at the Pennsylvania state line. This remained the case until 1937, when SR 305 was extended west along previously un-numbered roads across Trumbull County and into northeastern Portage County to its current western terminus in Hiram.
