Project Overview and Purpose

The N.C. Department of Transportation, along with the S.C. Department of Transportation, is planning to build a multi-lane expressway that extends 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 as well as Little River and the Grand Strand areas in South Carolina. It 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

A team of engineering firms, led by CALYX Engineers and Consultants, is under contract to conduct project development and environmental studies, which are being led by NCDOT and SCDOT in cooperation with local, state and federal agencies in both states.

The project team is expected to begin soliciting public input by the end of 2016.

Although the project is funded for study, right-of-way acquisition and construction are not currently funded.

Project History

In 2006, NCDOT and SCDOT completed a feasibility study to look at the project area for potential opportunities, impacts and challenges, as well as to get public input and to develop cost estimates for the project.

Conceptual alternative routes were developed as part of the feasibility study, but detailed environmental and engineering investigations were not performed. Changes to the conceptual alternatives are possible, and additional alternatives might be developed during the project development study.

In 2015, project development studies were funded by North Carolina. South Carolina is expected to help fund the study, although a funding source has not yet been identified.

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.
