Traffic Relief for Johns Island
and West Ashley

In 2018, Charleston County Council approved a phased, three-segment approach for the Main Road Corridor Project.

These much-needed projects will provide a more efficient access point on and off Johns Island by improving the intersection at US 17 and Main Road, in addition to further improvements along Main Road. The enhancements include improved drainage, bicycle and pedestrian facilities and widening from Bees Ferry Road to Betsy Kerrison Parkway, a distance of approximately 15 miles.
