The Orangeburg Road Roundabout Project was identified and planned by Dorchester County to reduce travel delays and improve safety at the intersection of Orangeburg Road and West Butternut Road in the Knightsville area.
The intersection currently experiences congestion and delays during periods of high traffic volumes, such as weekday morning and afternoons. Traffic backs up during these peak periods, forming queues of vehicles waiting to cross the intersection. The intersection also has a history of vehicular crashes occurring. These crashes can potentially be reduced through proper intersection improvements.
Why a Roundabout? The South Carolina Department of Transportation suggested a roundabout as the safest traffic solution for the area. In national studies, roundabouts have been found to reduce total crashes by 35%, crashes with injuries by 75%, pedestrian crashes by 40% and fatal crashes by 90%.
The Ridgeville Road (SC 27 N) widening and improvements project will consist of widening 0.94 miles of Ridgeville Road (SC 27 N) from two lanes to three lanes.
The project extends from US Highway 78, near the intersection of Kiser Lane to the Exit 187 interchange of I-26.
Phase 3 of the Berlin Myers Parkway consists of new construction of a 4-lane divided roadway from Bacons Bridge Rd. (SC 165) to US-17 Alterative.
Traffic projections estimate this roadway will carry between 18,000 and 23,000 vehicles per day by 2030.
