Interstate 526 (I-526) is a 19.56-mile (31.48 km) auxiliary route of I-26, providing a partial beltway around Charleston, South Carolina, in the United States. The route serves several purposes, firstly, as a bypass for through traffic on U.S. Route 17 (US 17) to avoid downtown Charleston, and, secondly, for traffic on I-26 bound for the coastal towns located north and south of Charleston. The route is not yet complete, as the western terminus it is planned for the route to be extended an additional 10 miles (16 km). After the eastern terminus, the roadway continues as a short business route, known as Interstate 526 Business (I-526 Bus.).
