Formerly an abandoned spur of the CSX system, the trail is part of the 5,500 mile coast-to-coast American Discovery Trail. Stretching 72 miles from I-77 near Parkersburg in Wood County to Wolf Summit in Harrison County, this scenic trail passes through 13 tunnels and crosses 36 bridges. Easily accessible from north/south Interstates 77 and 79, the trail nearly parallels US Route 50 east and west.
