Charleston County to improve major intersection traffic flow

Charleston County will begin construction in May on major traffic improvements at the intersection of Main Road and U.S. Highway 17. The project includes flyovers, an interchange, a bridge, and a roundabout, costing $354 million. This project is the largest infrastructure effort in Charleston County's history, funded by a 2016 transportation sales tax. Construction will primarily occur at night, but residents should expect traffic delays. While some residents are optimistic about the changes, concerns remain about ongoing congestion and the removal of a planned bike and pedestrian bridge. The project is expected to be completed by late September 2028.
