Carolina Bays Parkway Extension



In a cooperative effort, the  North Carolina and South Carolina Departments of Transportation are planning to construct a multi-lane extension of Carolina Bays Parkway.  

In South Carolina, the new expressway would begin at the existing Carolina Bays Parkway (S.C. 31) and S.C. 9 in Horry County and extend to the state line.  This would provide a direct route and allow more efficient traffic movement for those seeking to bypass congestion in the Little River and Grand Strand areas.  It would also improve traffic flow and safety at the intersection of S.C. 9 and S.C. 57.

In North Carolina, the project would begin at the state line and continue to U.S. 17/Shallotte Bypass in Brunswick County. This would provide a direct route and allow more efficient traffic movement for those seeking to bypass congestion in the Calabash area.  Another benefit would be a more direct route for coastal truck traffic.

Interactive Study Area Map* Coming Soon



The study area map provides the outline of an area in which environmental data, both human and natural, as well as other data will be gathered and evaluated.  Potential routes will be identified, within this area.


NCDOT and SCDOT are not responsible for accuracy or use.  These maps are for general information purposes only.  


*The study area is preliminary and will be approved or modified at the  upcoming "Merger Team" meeting. 

Merger is a process to streamline the project development and permitting processes, agreed to by the USACE, NCDENR (DWQ, DCM), FHWA and NCDOT and supported by other stakeholder agencies and local units of government. To this effect, the Merger process provides a forum for appropriate agency representatives to discuss and reach consensus on ways to facilitate meeting the regulatory requirements of Section 404 of the Clean Water Act during the NEPA/SEPA decision-making phase of transportation projects. 
 The Merger Process allows agency representatives to work more efficiently (quicker and comprehensive evaluation and resolution of issues) by providing a common forum for them to discuss and find ways to comply with key elements of their agency's mission. The merger process helps to document how competing agency mandates are balanced during a shared decision-making process, which results in agency representatives reaching a "compromise based decision" to the regulatory and individual agency mandates.  


  Jurisdiction Estimated Cost*
  North Carolina $  367  million 
  South Carolina $  185  million 
  Total Cost $  522  million 

* Estimated Costs subject to change

The project is funded for study. 

No schedule has been established for right-of-way acquisition or construction in South Carolina. 

Neither right-of-way nor construction is funded in North Carolina.


The engineering firm of CALYX Engineers and Consultants is under contract to conduct project development and environmental studies.  These studies are being led by NCDOT and SCDOT in cooperation with local, state and federal agencies in both states.   The studies will evaluate potential routes for the roadway from an engineering and environmental standpoint.


2006:     NCDOT and SCDOT completed a feasibility study looking at the project area for potential opportunities, impacts and challenges as well as obtaining public input and development of cost estimates for the project.














View or download a copy of the Feasibility Study here:    Carolina Bays Parkway Extension - Feasibility Study 


2015:     The N.C. General Assembly authorized $1.2 million of North Carolina's share of the project development study

2016:     Horry County, S.C. passed a Capital Projects Sales Tax Referendum allocating $125 million for South Carolina's share of the project development study. 


Public Input will be an extremely important part of this project development process.  As such, a number of small group and open-house public meetings will be held throughout the process.  Information and maps will be available on this site as well as on the NCDOT project website  

The NCDOT/SCDOT team will review all feedback – regardless of how it is submitted (online, phone, email, or letter) – and explore options to incorporate and address concerns where and when feasible.  The team will continue to develop the project and present progress throughout the planning stage.

Persons who speak Spanish and do not speak English, or have a limited ability to read, speak or understand English, may receive interpretive services upon request prior to any meeting by calling 1-800-481-6494.


Comments may be submitted at any meeting, online, via phone, email or U.S. Mail to either of the individuals listed below.  All comments received carry equal weight, regardless of submittal method.  All comments will be reviewed and suggestions/recommendations incorporated into designs where feasible.

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.
