The northern terminus is near WV 9 near Baker Heights at an intersection with Opequon Lane.

North of Ranson, it parallels WV 9 before crossing under it in Bardane.

WV 115 continues for 750 feet (230 m) to end at Opequon Lane.

[1] When the Charles Town bypass was built between April 1996 and March 1997, the designations of U.S. 340 and WV 9 were moved to the new four-lane highway.

Finally in November 2012, a new four-lane highway between Charles Town and the Virginia state line near Keyes Gap was constructed and assigned to WV 9, which extended WV 115 through its old, curvy alignment.
