The section of U.S. Route 13 (US 13) in North Carolina is the largest, home to 185.52 miles (298.57 km) of its length. It runs southwest to northeast through eastern North Carolina, beginning at Interstate 95. Most of the routing is rural, serving only three cities of considerable size along the entire route; the rest passes through forests and farmland. US 13 is usually only two lanes wide unless it is co-signed with other highways, usually near cities as bypasses.
