CASTLE HAYNE – The N.C. Department of Transportation is considering new design options for the Carolina Bays Parkway Extension project shaped by public and stakeholder feedback.
In collaboration with the S.C. Department of Transportation (SCDOT), planning and development are ongoing to extend S.C. 31 (Carolina Bays Parkway) from S.C. 9 in Horry County, S.C. across the state line to U.S. 17 in Brunswick County.
The project proposes a multi-lane highway using portions of the existing road and building on new locations.
In October 2025, NCDOT and SCDOT held two joint corridor public hearings regarding the project. Seven different design alternatives were presented, including the Departments’ Preferred Alternative (Alternative 4).
After reviewing public feedback and considering funding challenges, NCDOT will not be moving forward with the North Carolina portion of Alternative 4, which builds on new location, tying in near the intersection of U.S. 17 and N.C. 904. Alternative 4 also upgrades a portion of U.S. 17 to a fully controlled freeway from N.C. 904 to N.C. 130 in Shallotte.
NCDOT, SCDOT and the Federal Highway Administration (FHWA) continue to collaborate and explore other alternatives and modified routes to minimize impacts and meet the purpose and need of the project.
“NCDOT deeply values the input from this community and our stakeholders. We want to provide the region with the best possible roadway designs. We’ve listened to the feedback, and we’re working hard to prepare a new alternative,” said Division 3 Engineer Trevor Carroll.
A new alternative must include connectivity through the transportation network, increased mobility for the region and reduced travel time through the project corridor.
Additional information regarding the new design will be presented to the public at a later date.
The Department is committed to transparency, innovative solutions and exploring community feedback regarding this project. A response to all comments received is available on the project webpage along with the most updated information regarding the project. Follow NCDOT on social media for additional updates.
