SR 243 used to continue east from here, running concurrently with SR 7 into Proctorville, then split briefly from SR 7 as it passed through the community of Rome before ending at SR 7 about 3 miles (4.8 km) east of Proctorville.
History
SR 243 between SR 7, in Proctorville, and SR 7 northeast of Proctorville, was signed in 1923 as SR 219.[4][5] In 1925, SR 219 was replaced by SR 243.[2][3] This section of road was paved in 1929.[6][7] The western terminus was moved west to Coal Grove, concurrent with SR 7 through Proctorville, in 1932.[8][9] The paving of the route between Coal Grove and Proctorville was completed by 1955.[10][11] On December 11, 2006, SR 243 was truncated to its present location following completion of the new SR 775 by-pass of Proctorville, which SR 7 was re-routed onto, leaving jurisdiction of the former routings of SR 7 and SR 243 through Proctorville to be turned over from the state to the local jurisdictions.[12]
