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.

Project development and environmental studies are underway to evaluate potential routes for the roadway from an engineering and environmental standpoint and to select a preferred route.

Although the project is funded for study, no schedule has been established for right-of-way acquisition or construction, which are not currently funded in North Carolina.

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, the N.C. General Assembly appropriated $1.2 million for North Carolina’s share of the project development study. In 2016, Horry County passed a capital projects sales tax referendum allocating $125 million for the portion of the project in South Carolina.

Resources for Local Property Owners

Although the N.C. Department of Transportation works to minimize the number of homes and businesses displaced by a road project, it is inevitable, in many cases, that a certain amount of private property is needed. The following information explains right of way acquisition and answers questions about the process.
