Project Background: Alternatives Evaluation & Public Involvement

The process has worked, and the project team was able to identify a Compromise Alternative that is reflective of the needs of surrounding communities while also managing the growing traffic congestion along Highway 41.

All Alternatives Updates as well as presentations to the public, stakeholders and Council can be found on the Resources page.

The project team is committed to continuing to work closely with surrounding communities and stakeholders as the project design, Environmental Report, U.S. Army Corps of Engineers (USACE) permit application, and the South Carolina Department of Environmental Services (SCDES) permit application are being reviewed.

Updated versions of the Environmental Report and Supporting Documentation may be viewed here, and more information can be found at USACE - SC 41 Corridor Improvements Charleston County, South Carolina.

The project's right-of-way plans have been finalized and are currently under review by SCDOT.
