State Route 676 (SR 676) is a 26.53miles long east - west state highway in the southeastern portion of the U.S. state of Ohio. The western terminus of SR 676 is at a T-intersection with SR 555 approximately 3miles southeast of the village of Chesterhill. Its eastern terminus is at a T-intersection with SR 7 in the southwestern portion of the city of Marietta.
SR 676 traverses the western portion of Washington County and a small portion of southern Morgan County. There are no segments of SR 676 that are a part of the National Highway System (NHS), a network of route determined to be most important for the economy, mobility and defense of the country.[3]
The SR 676 designation was established in 1937. It has utilized the same routing between SR 555 near Chesterhill and SR 7 near Marietta throughout its history. Initially, the entire length of SR 676 was a gravel roadway.[4] [5] In 1947, the easternmost stretch of SR 676 between County Road 183 (CR 183) and SR 7 was paved.[6] [7] Four years later, the highway was hard-surfaced between the present SR 339 junction, at the time designated as SR 76, and CR 183.[8] [9] The remaining gravel portion of SR 676 between SR 555 and the current SR 339 intersection was paved by 1961.[10] [11]
