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, from Moss Creek Drive to Spanish Wells Road. The purpose of this project is to address structural deficiencies at the existing eastbound MacKay Creek bridge, to increase capacity, and reduce congestion along US 278 from Moss Creek Drive to Spanish Wells Road.

The eastbound Mackay Creek Bridge will be replaced; it was originally built in 1956 and is scheduled for replacement. Additional studies for potential improvements include:

  • Modifications to the remaining three bridges;

  • Improved access to Pinckney Island National Wildlife Refuge; and

  • Improved access to the C.C. Haigh, Jr. boat ramp.

Community involvement and communication will be a primary focus of the project to ensure successful development of the environmental process. Additionally, SCDOT will be working hand-in-hand with the Federal Highway Administration and Beaufort County. The project is to be funded using federal, state, and local funds.

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.
