Highway 31 runs parallel to U.S. Highway 17, providing a faster, less congested north–south route through Horry County. The highway stretches from near Little River in the north down toward Socastee in the south, with multiple interchanges that connect to Highways 9, 22, 501, and 544.
A recent phase of Highway 31 was officially completed and opened to traffic on November 7, 2019. This extended Highway 31 from SC 544 down to SC 707, creating a six-lane, limited-access thoroughfare that greatly improves regional traffic flow.
One of the final Horry County RIDE 3 projects is the final phase of Highway 31 and would extend Carolina Bays Parkway from its current location at SC Highway 9 in Horry County to the North Carolina state line.
The broader Highway 31 project would extend Carolina Bays Parkway across the North Carolina state line to U.S. 17 in Brunswick County, North Carolina, near Shallotte.
Due to the nature of the project being worked across multiple states, the project is a collaboration between the S.C. Department of Transportation (SCDOT) and N.C. Department of Transportation (NCDOT)
There are two Open-House public meetings being held at the end of September on the project and offer residents and stakeholders an opportunity to review plans, ask questions, and share feedback on the project’s potential effects.
