State Route 207 (SR 207, OH 207) is a 31.23-mile (50.26 km) long north–south state highway in the southern portion of the U.S. state of Ohio. The southern terminus of SR 207 is at a diamond interchange with U.S. Route 23 (US 23) nearly 4 miles (6.4 km) north of Chillicothe. Its northern terminus is in Mount Sterling, following a 0.33-mile (0.53 km) long concurrenty with US 62 and SR 3, at the intersection where they meet SR 56.

Route description

Along the way, SR 207 passes through northern Ross County, southwestern Pickaway County, northeastern Fayette County and extreme southeastern Madison County. There are no segments of this highway that are included within the National Highway System (NHS). The NHS is a network of highways identified as being most important for the economy, mobility and defense of the nation.^[7]

History

SR 207 was assigned in 1962. Running along the majority of SR 207's present path, excepting the southernmost portion of the highway between US 23 and SR 104, along with the SR 104 concurrency, the designation replaced the entirety of what was SR 277 prior to that year. The change was necessitated by the coming of the Interstate Highway System to Ohio, which included construction of Interstate 277 in the Akron vicinity. Ohio follows a standard that no route number can be duplicated between different types of state highways, so SR 277 became SR 207.^{[1] [2]}

By 2007, SR 207 was extended on the south end via a nearly 0.50-mile (0.80 km) duplex with SR 104, and an all-new alignment running east from SR 104 across the Scioto River to a new interchange with the US 23 expressway in northern Ross County, north of Chillicothe.^[8][9]
