Congestion Relief for the HWY 78 Corridor 

In 2016, citizens of Charleston County voted to include improvements to HWY 78 as a Project of Local Significance in the Half Cent Sales Tax Referendum Ordinance. Charleston County is developing improvements in a four-phased approach to accommodate an increase in traffic volume by improving roadway capacity, efficiency of key intersections, and system continuity throughout the project limits.
The first public meeting was August 31, 2021.

HWY 78 Project Overview

Charleston County, in partnership with the South Carolina Department of Transportation (SCDOT) is proposing to make improvements to HWY 78 from Rivers Avenue (US 52) to the intersection of HWY 78 and Berlin G. Myers Parkway (SC 165). The Project is generally located along the existing alignment of HWY 78 for approximately 8.0 miles between Rivers Avenue and Berlin G. Myers Parkway. 

This project is currently funded by Charleston County as part of the Transportation Sales Tax Program. The project will follow the provisions of the National Environmental Policy Act (NEPA) as to remain eligible for federal funding and to ultimately comply with provisions of Section 404 of the Clean Water Act.
