History

SR 138 was first designated on its current route between Hillsboro and Greenfield in 1923, though the road had been a part of the state highway system since its creation in 1912 as SR 260.^[3][4][5] The route was extended in 1937 from its two ends to the route it travels today.^[6][7] No major changes to SR 138's routing have occurred since then.^{[citation needed]}
