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.
