Driving from Mountain City, Tennessee to Damascus, Virginia

Near downtown Mountain City, SR-91 splits off from US-421/SR-34 to once again follow a northeastward trek. It continues through a series of gradual ascents and descents across rugged terrain before reaching Laurel Bloomery in the northeastern part of the county. SR-91 meets its northern terminus at the Virginia state line, near Damascus, where the roadway continues as Virginia State Route 91 into Washington County, Virginia, and the Jefferson National Forest.[
