Highway 41 Corridor Improvements

Compromise Alternative

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.

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
• Adds a two lane southern parkway from Highway 41 to Park West Boulevard along the edge of Laurel Hill County Park.
• Includes changes from earlier alternatives to reduce right-of-way impacts at the Highway 17 intersections with Highway 41 and Winnowing Way

Benefits of the Compromise Alternative include:

• Minimization of impacts to the Phillips Community
• Elimination of property impacts to Seven Mile at the 41/17 connections
• Multiple route options through this corridor, such as the addition of lanes on 41 and the Laurel Hill Parkway, which will also benefit first responders to access incidents and provide evacuation routes
• High visibility bike and pedestrian accommodations at intersections
• Designs that incorporate flood prevention and water quality standards, including diversion of stormwater away from communities before properly treating it and discharging it into nearby creeks
• Reducing congestion and accommodating future traffic projections for the next 20 years
