It is mainly a two-lane road except for the easternmost and westernmost parts. Near Athens it runs concurrently with State Route 32 (SR 32), a four-lane divided highway known as Corridor D, and from Coolville to the Ohio–West Virginia border it also overlaps SR 7 before crossing into Parkersburg, West Virginia.
