Carolina Bays Parkway Extension Study Logo


The Carolina Bays Parkway (CBP) extension project involves the development of a new multilane full control of access highway facility. In South Carolina this facility will extend the CBP from SC 9 northerly approximately five miles to a logical terminus at the South Carolina / North Carolina State line. The North Carolina Department of Transportation in coordination with the South Carolina Department of Transportation (SCDOT) is concurrently developing a feasibility study to extend the multi-lane facility from the state line approximately five miles northeasternly to US 17 in Brunswick County, North Carolina.

The development of this new controlled access facility is intended to provide a more direct and efficient movement of north-south traffic seeking to bypass congestion within the Calabash, Little River and Grand Strand areas and will be the integral part of the proposed Interstate 74 where it would extend into South Carolina from North Carolina. Development of this project will also improve traffic flow and safety at the SC-9/S-57 Intersection and provide a more direct route for coastal truck traffic moving through North Carolina.

The purpose of the feasibility study is to examine the area for potential opportunities and challenges (such as impacts), receive public input and feedback, and develop cost estimates for the project. Recommendations from the study are only conceptual in nature, not the product of extensive environmental or design studies, and are subject to change without notice. At this time, there is no funding for additional phases of the project.

Project Development

Initial efforts by the SCDOT and NCDOT have been made to establish preliminary coordination with permitting and resource agencies to ensure ample consideration of the project's potential for impacting cultural and natural resources within the area. Input from these agencies has been considered and incorporated during the development of this important project.

Prior to conducting public information meetings in both states, the current study had identified six alternative corridors. Based upon input gathered during the first North Carolina public information in February 2004, NCDOT decided to expand the study area and examine two additional corridors, while also consolidating two corridors (due to similarities).

Study Report

The Carolina Bays Parkway Extension Feasibility Study Report is a comprehensive document, which encompasses the activities, evaluations, comments, and recommendations developed for the study.

Community Involvement

An initial set of public information workshops were held in February 2004 to introduce the project, obtain feedback and answer questions. Two workshops were held, one in North Myrtle Beach, SC on February 12, 2004 and the other in Ash, NC on February 24, 2004. Representatives from NCDOT, SCDOT, and the consultants working on the study were there to discuss the project at both workshops. Input received was generally positive, as both the public and local officials are in favor of an extension of the Carolina Bays Parkway into North Carolina. A desire was also voiced at the workshop in North Carolina to expand the study area and examine additional corridor alternatives. As a result of this input, NCDOT decided to expand the study area and examine two additional corridors, while also consolidating two of the original alternatives.

A second public information workshop was held on October 11, 2005 in Ash, NC to solicit input on the revised set of six alternatives, which included two new corridors developed as a result of the initial workshops.

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.
