Ohio State Route 140

Along its way, State Route 140 travels through eastern Scioto County, clips the northwestern corner of Lawrence County and then sneaks into southern Jackson County. State Route 140 is not a part of the National Highway System, a system of highways deemed most important for the nation's economy, mobility and defense. ==History==

State Route 140 was established in 1923. The original routing of the highway is the one which it still utilizes to this day through Scioto, Lawrence and Jackson Counties. The highway has not experienced any major changes since its inception, excepting the highways that it intersects at its endpoints. Its western terminus, which is now U.S. Route 52, was originally a part of State Route 7. Meanwhile, its eastern terminus, which is currently State Route 93, was originally designated as State Route 75. ==Major intersections==
