Route description

SR 31 begins at a junction with US 11W/SR 1 in Mooresburg. The highway heads north into rural Hawkins County, passing through the community of Spruce Pine. While crossing over Clinch Mountain, the route crosses into Hancock County.^[3] Past the mountain ridge, the highway intersects SR 131 in Treadway and briefly becomes a four-laned undivided Highway and continues northward through Luther and Duck Creek before turning northeast along the Clinch River.^[4] The route then enters Sneedville, where it terminates at SR 66, which connects to SR 33 and Sneedville via a bridge.

The entire route of SR 31 is a narrow rural 2-lane mountain highway. ^[5]
