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, in partnership with the South Carolina Department of Transportation (SCDOT), evaluated potential improvements to HWY 78 for approximately 8 miles from Rivers Avenue (US 52) to the intersection of HWY 78 and Berlin G. Myers Parkway (SC 165).

Based on traffic analysis, impact analysis, costs, and public input, Charleston County has determined that only improvements at the HWY 78/College Park Road/Ladson Road intersections will be advanced at this time.

Charleston County hosted a Public Meeting on May 8, 2024 to present alternatives based on findings of traffic studies completed for the corridor. Enter the Virtual Public Meeting →

HWY 78 Project Status

The Project Team completed a Traffic Study that analyzed the existing and future conditions for the no-build and the build alternatives. This study looked at Level of Service at intersections along the corridor and segments of HWY 78. Four alternatives for corridor improvements were developed that included different levels of improvements along the corridor. All of the alternatives included improvements to the intersections at College Park Road and Ladson Road.

Based on traffic studies, public and stakeholder comments, and cost, Charleston County has determined that only improvements at the Hwy 78/College Park Road/Ladson Road intersections will be advanced. Other components of the Hwy 78 Project will not be implemented at this time.
