Located in the heart of Mount Pleasant, Highway 41 is a key corridor connecting the traveling public along US 17 in Charleston County to communities in Mount Pleasant and to I-526. The Highway 41 Corridor Improvements project is a top priority of Charleston County, the Town of Mount Pleasant, and the South Carolina Department of Transportation.

The project is needed to address local and regional growth, increased traffic congestion, safety and emergency response concerns, and inadequate interconnections of transportation modes, including pedestrian and bicycle facilities.

In August 2021, Charleston County Council voted to move the Compromise Alternative forward through the environmental review process and further into design. Learn more about the Compromise Alternative and project development process here.
