The NC Department of Transportation and the SC Department of Transportation plan to extend Carolina Bays Parkway (S.C. 31) from S.C. 9 in Horry County, SC, across the North Carolina state line to U.S. 17 in Brunswick County. The project is expected to involve the construction of a multi-lane expressway and may involve both existing roadways and areas on new location.

SCDOT State Transportation Improvement Program (STIP) Project P029554 would extend Carolina Bays Parkway from its current terminus at S.C. 9 in Horry County to the North Carolina state line. NCDOT STIP Project R-5876 would extend Carolina Bays Parkway from the state line to U.S. 17 Shallotte Bypass in Brunswick County. Carolina Bays Parkway Extension is anticipated to involve the construction of a multilane, full control of access freeway, with part on new location. Full control of access means that access to Carolina Bays Parkway will only be provided via ramps and interchanges. Bridges will be installed at some cross streets and no driveway connections will be allowed.

Carolina Bays Parkway Extension Study Area

The Carolina Bays Parkway Extension project area is largely comprised of unincorporated areas in Horry and Brunswick counties, but also includes portions of some coastal towns and communities located on the inland side of the Intracoastal Waterway.

A study area is a geographical area in which information on human and natural environmental features are gathered during the preliminary planning phase. The Carolina Bays Parkway Extension study area boundary was established with consideration given to the ability to develop a full range of alternatives while also minimizing potential impacts to important environmental features. The project study area is approximately 19 miles long, with approximately five miles located in South Carolina and 14 miles located in North Carolina.

The existing primary road network includes U.S. 17 and various North Carolina and South Carolina state highway and secondary routes. There are no interstate facilities in the project area and access along existing routes is largely uncontrolled. Outlined in red in the map below, the study area is much larger than the actual amount of land that would be directly impacted by the project and is subject to change as more information about the project is collected.


NCDOT and SCDOT, in coordination with the Federal Highway Administration (FHWA),held two Public Information Meetings on the proposed extension of Carolina Bays Parkway (S.C. 31).

Nine Corridor Concepts have been developed for the proposed project. The nine Corridor Concepts are shown on the aerial photograph image below. Corridor concepts may be viewed individually by clicking on the corridor concept map links below.

Each of the nine Corridor Concepts begin at the existing Carolina Bays Parkway/S.C. 9 interchange in South Carolina and end at the U.S. 17 Shallotte Bypass in North Carolina. The location of the tie-in to existing U.S. 17 varies by corridor concept; however, all concepts would use existing U.S. 17 for approximately 6.3 miles between N.C. 904 (Longwood Road/Seaside Road) and N.C. 130 in Brunswick County. Three existing intersections are proposed for conversion to interchanges along this section of U.S. 17, including N.C. 904, Ocean Isle Beach Road, and U.S. 17 Business (Main Street). 

The nine Corridor Concepts were developed to minimize impacts to natural and human environment features such as homes, businesses, wetlands, and streams. The Corridor Concepts shown are much wider than the area needed for a future road. The study corridors shown are generally 1,000 feet wide, but the recommended right-of-way width will be much narrower, in general approximately 400 feet. The 1,000-foot width of the study corridors was chosen to provide opportunities to further minimize impacts to homes, businesses, and natural resources as the project continues to develop.

The primary purpose of the project is to improve the transportation network in the study area by enhancing mobility and connectivity for traffic moving in and through the project area.

Many intersections and roadway segments in the study area are expected to either approach or exceed the roadway capacity limits in 2040. In addition, the population within Horry and Brunswick counties has steadily increased, and is expected to continue to increase, along with the number of tourists to the area. Growth in population, tourism, and supporting services has resulted in an increase in mixed-purpose traffic on area roads.

Potential additional benefits of the proposed project may include:

  • The proposed project offers the potential to reduce the number and severity of vehicle crashes by providing an alternate route to travelers. Separating through traffic from the local traffic that is using the existing roadways to access schools, shopping and services, and residential areas will likely enhance safety.
  • By providing additional capacity and improving mobility in the project area, the proposed project offers the potential to support more efficient clearance times during emergency evacuations.

What are the Steps in the Project Planning Process?

The planning process can be divided into the steps shown below. Public involvement is an important component of the planning process and opportunities, both formal and informal, will be provided throughout the process so citizens can stay informed and provide input.

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.
