Project Overview

The Carolina Bays Parkway Extension project involves developing a new multi-lane limited-access highway that would 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 extension would provide a more direct and efficient movement of traffic seeking to bypass congestion within the areas of Calabash in North Carolina and Little River and the Grand Strand area in South Carolina. It would also be an integral part of the proposed Interstate 74, where it would extend into South Carolina from North Carolina.

Development of this project would also improve traffic flow and safety at the intersection of S.C. 9 and S.C. 57 and provide a more direct route for coastal truck traffic moving through North Carolina.

Project Highlights

This project is now funded for project development and environmental studies, although right-of-way acquisition and construction are not currently funded.

A request for letters of interest from engineering firms to conduct the project development study was posted on Feb. 1, 2016. Project development studies are expected to begin in mid-2016, following the selection of a firm.

Feasibility Study

The N.C. Department of Transportation, in coordination with the South Carolina Department of Transportation, conducted a feasibility study to examine the area for potential opportunities, impacts and challenges, as well as to receive public input and develop cost estimates for the project.

Completed in 2006, the Carolina Bays Parkway Extension Feasibility Study Report, listed below, is a comprehensive document that encompasses the activities, evaluations, comments and recommendations for the project.

Detailed environmental and engineering investigations were not performed as a part of the feasibility study. The alternatives shown in the feasibility study and on this page are conceptual alternatives. Changes to these alternatives or additional alternatives may be developed during the project development study.

The public will be kept informed of the progress of the project development study through meetings, newsletters and a Web page.

Resources for Local Property Owners

In many cases, it is inevitable that a certain amount of private property must be acquired. The displacement of homes and businesses is minimized to the extent practicable. The following brochures will answer questions about this process.
