US 278 Corridor Improvements

Casting a Light on the Community's Transportation Future


Project Information

The South Carolina Department of Transportation (SCDOT) is proposing to make improvements to the US 278 corridor between Bluffton and Hilton Head Island. The project includes studying the US 278 Corridor from Moss Creek Drive to Squire Pope Road to increase capacity, which will have secondary improvements to overall mobility, congestion, and safety. The eastbound Mackay Creek Bridge, which crosses the Intracoastal Waterway, is structurally deficient and would be replaced. Access to Pinckney Island National Wildlife Refuge and the C.C. Haigh, Jr. boat ramp would be improved as well.

SCDOT will move this important project forward through the planning phase with an environmental assessment (EA), with the eventual goal of acquiring right-of-way and construction. In association with FHWA and Beaufort County, SCDOT will develop the EA, a process that will include reviewing alternatives and comparing the beneficial and negative impacts on the natural and human environments.

Efforts will be focused on community involvement and communication to ensure the successful development of the environmental process. Due to the major roles state and federal resource agencies play, the project team will work closely with them in completing the environmental review process.

The project is to be funded using federal, state, and local funds. Right-of-way acquisition for this project is tentatively scheduled to begin in 2021.

Public Information Meeting

A public information meeting was held on Thursday, September 27, 2018, between 6:00 pm and 8:00 pm. The purpose of the public information meeting was to introduce the project to the community, gather initial comments from the public, identify the needs for the project, and help identify concerns the people may have about the improvements or the project's impact to the natural and human environments.


The proposed schedule is for the planning process and the completion of the Environmental Assessment. We are at the beginning phases of the process having recently held the initial Public Information meeting on September 27, 2018.
