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.
Prior to the roundabout, the intersection experienced congestion and delays during periods of high traffic volumes, such as weekday morning and afternoons. Traffic backed up during these peak periods, forming queues of vehicles waiting to cross the intersection. The intersection also had a history of vehicular crashes occurring.
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%.
In order to fund this project, Dorchester County successfully obtained $1.25 million from the South Carolina State Infrastructure Bank (SCTIB) Local Agency Fund, $750,000 from the Highway Safety Improvement Program (HSIP) funds and $850,000 in Dorchester County Capital Funds.
Local Public Agency funds are federal or state transportation funds programmed through SCDOT and made available to qualified agencies for specified projects. HSIP funds are Federal Highway Administration (FHWA) project-specific funds administered through SCDOT’s Safety Office.
