High Quality Content by WIKIPEDIA articles! Interstate 440 (abbreviated I-440) in North Carolina, also known as the Raleigh Beltline and the Cliff Benson Beltline, is a 16.4-mile (26.4-km) partial beltway that nearly encircles central Raleigh. Prior to August 2002, it was a complete loop and shared a concurrency with its parent, Interstate 40 along the loop`s southern segment (Tom Bradshaw Freeway). I-440 was labeled with "Inner" and "Outer" lanes, making it one of the few Interstate Highways in the United States not primarily labeled with compass directions (e.g. east/west). It has now been truncated to avoid confusion, especially with the I-540 "Outer Loop" and is being relabeled with an east–west orientation.
