Carolina Bays Parkway Extension

​​​​​​​​​​​​​​​​​​​​​​Project Overview

Planning and development are underway by the N.C. Department of Transportation and the S.C. Department of Transportation to extend Carolina Bays Parkway (S.C. 31) from S.C. 9 in Horry County, S.C., across the North Carolina state line to U.S. 17 in Brunswick County.

The proposed project would build a multi-lane highway and use some of the existing road, plus build-on new locations.

As a result, local and tourist traffic on area roadways would experience less congestion and delays.​
