Williamson Road is an approximately 8.0 mi (12.9 km) long road in Roanoke City and Roanoke County, Virginia. The road runs from downtown Roanoke in the south through the Botetourt County line in the north. For the majority of its length Williamson Road carries U.S. Route 11. The road was named after the former Williamson farm through which a portion of the road was constructed after Virginia obtained the land through eminent domain.[1]
