River Road

On Feb 11, 2023, Rational Roads published their "Upper River Road Survey Results" which detail the view of residents on what improvements should be made on upper River Road.

To facilitate the New Elementary School, the Charleston County School District (CCSD) is currently planning the following road upgrades:   

• Add a roundabout on River Road at the entrance to the school
• Add turn lanes at Brownswood: a left turn on River Road to Brownswood Road and a right turn on Brownswood Road to River Road

The Mark Clark Extension envisions improvements at the proposed on/off ramp located near Rushland Landing Road (“Connector A”).  Click here to see the map.

The County is planning to repave this road in 2023.  

• The project manager for that effort is Mackenzie Kelley.

The only other improvements that would occur are those that would be required by SCDOT for new developments, e.g. turn lanes.

The Main Road Corridor Project Segment C may impact lower River Road.  Three of the alternatives for this project envision changes to River Road north of Plow Ground Road.  Most of the alternatives envision changes to the River/Bohicket/Betsy Kerrison intersection.

The Mark Clark Extension envisions improvements at the proposed on/off ramp located near Rushland Landing Road (“Connector A”).  Click here to see the map.

To accommodate developments along Cane Slash Road, the developer will put turn lanes add turn lanes at the River Road and Cane Slash Road intersection.

The Wooddale development (430 lots) near River and Plow Ground Roads will add left and right turn lanes for their development on River Road .  

The only other improvements that would occur are those that would be required by SCDOT for new developments, e.g. turn lanes.

Even if this Mark Clark Extension project were completed in 2030 (it is not anticipated to be completed until 2036), the traffic on River and Brownswood Roads as a result of this project results in unacceptable levels of service (green is good, red is bad, maroone is even worse).   Therefore there needs to be improvements to theses roads of the the project goes forward.  There is no identified funding for this effort.
