South Carolina Highway 31 (SC 31) is a six-lane Interstate Highway standard freeway that parallels (in most cases) the Intracoastal Waterway from Myrtle Beach, and is also called the Carolina Bays Parkway. The first phase opened on December 17, 2002, completing a 22-mile (35 km) link between U.S. Route 501 (US 501) and SC 9. The second phase opened in March 2005, running from US 501 southwest to and S.C. Highway 544. While the freeway is colloquially referred to as the Carolina Bays Parkway, the South Carolina General Assembly also designated the highway to be named the John B. Singleton Parkway in April 2000 in memory of John B. Singleton, a former Myrtle Beach City Council member and police commissioner.
