South Carolina Highway 30 (also known as the James Island Expressway or the James Island Connector) is a 3 mile long freeway in Charleston County, South Carolina, United States. The freeway runs from South Carolina Highway 171 in James Island to U.S. Route 17 in Charleston.

Route description

SC 30 begins at South Carolina Highway 171 in James Island, at exit 3. From there, the highway runs northeast, and has two interchanges south of the Ashley River crossing. Exit 2 has access to Harbor View Road and exit 1 is for the Herbert U. Fielding Connector (SC 61).

The route is an orphaned segment of Interstate 526. Approximately 10 miles separate the eastern terminus of SC 30 from the western terminus of I-526's current extent. Mileage markers and exit numbers on both SC 30 and I-526 are based on an eventual merging of the routes: with miles 1 to 3 occurring on SC 30 and miles 13 to 30 used on the current I-526 route.

History

The route was proposed as early as the 1960's to provide a second and more direct connection between James Island and downtown Charleston. It opened on September 4, 1993 and provided a route off the island that did not require crossing a drawbridge.Citation
