Highway 41 Corridor Improvements

On Tuesday, August 24, 2021 Charleston County Council voted 9-0 to move the Compromise Alternative forward through the environmental review process and further into design. Since the project kicked off in 2017, the Charleston County project team has diligently followed a rigorous environmental review process, which included extensive public involvement and a detailed alternatives evaluation to examine environmental, social, cultural, and economic impacts of the proposed project. 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.

The Compromise Alternative consists of two travel lanes in each direction from the Wando River Bridge to Dunes West Boulevard/Rivertowne Parkway, one lane in each direction with a center turn lane/median through Phillips Community, two travel lanes in each direction from south of Joe Rouse Road to Highway 17, and adds a two lane southern parkway from Highway 41 to Park West Boulevard along the edge of Laurel Hill County Park. The Compromise Alternative also includes changes from earlier alternatives to reduce right-of-way impacts at the Highway 17 intersections with Highway 41 and Winnowing Way.

This Compromise Alternative was originally presented to Charleston County Finance Committee on August 5, 2021 and a link to the presentation is located here.

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 South Carolina Department of Health and Environmental Control (SCDHEC), now known as the South Carolina Department of Environmental Services (SCDES), permit application are being reviewed. Final versions of the Environmental Report and Supporting Documentation may be viewed here.

Charleston County submitted a permit application, Environmental Report, and supporting documentation to the USACE in May 2023. USACE is currently undergoing its permitting process. A 30-day Public Notice comment period was held from June through July 2023. More information can be found at USACE - SC 41 Corridor Improvements Charleston County, South Carolina.

The SCDES permit application and supporting documentation was submitted to the SCDES in December 2023. SCDES is currently undergoing its permitting process and held a public hearing regarding the permit application in June 2024.
