State Route 91 (SR 91) is a primary state highway in the U.S. state of Virginia. The state highway runs 55.12 miles (88.71 km) from the Tennessee state line near Damascus, where the highway continues as Tennessee State Route 91 (SR 91), north to U.S. Route 19 Business (US 19 Business) and US 460 Business at Frog Level. SR 91 connects Damascus in southeastern Washington County with the northeastern county town Glade Spring, where the highway has junctions with US 11 and Interstate 81 (I-81). The state highway also indirectly connects Saltville in northwestern Smyth County and Tazewell, the county seat of Tazewell County. SR 91 is the only primary state highway in Virginia with an unpaved section; this gravel section is in southern Tazewell County.
