High Quality Content by WIKIPEDIA articles! U.S. Route 311 is a United States highway that runs for 85.2 mi (137.1 km) entirely within the state of North Carolina. On its route from Eden it passes through the cities of Madison, Winston-Salem and High Point. Originally a spur route from US 11 starting in Roanoke, Virginia and ending at Rowland, North Carolina, much of the route was absorbed by US 220 in 1934. Now mostly serving as an alternate routing of U.S. 220, this highway mainly connects Rockingham County with Forsyth, Guilford, and Randolph Counties.
