South Carolina Highway 31 (SC 31), also known as the Carolina Bays Parkway, is a six-lane, limited-access highway that parallels (in most cases) the Intracoastal Waterway from Myrtle Beach. 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 usually referred to only as the Carolina Bays Parkway, the highway is also dedicated the John B. Singleton Parkway in memory of John B. Singleton, a former Myrtle Beach City Council member and police commissioner.
