Construction will begin soon to convert the “T” intersection at Peachtree Corners Circle and Medlock Bridge Road in Peachtree Corners.
Currently traffic on Peachtree Corners Circle is controlled by a stop sign at this intersection that has a daily traffic count of over 25,000 vehicles. Studies show that roundabouts are safer than signalized intersections and prevent the severity of accidents as it eliminates any crossing points.
“Roundabouts promote a continuous flow of traffic in all directions versus a traditional traffic signal that stops at least one direction at all times,” said Public Works Director Greg Ramsey. “The roundabout allows for a greater volume of traffic through an intersection while minimizing delays, particularly during off peak hours.”
The proposed roundabout will also incorporate pedestrian crosswalks and additional signage to alert drivers of the state law which requires that all traffic must stop when a pedestrian is in the crosswalk.
Construction costs for roundabouts and signalized intersections are similar, but the cost to maintain a roundabout is projected to be less. Final construction cost is about $1.2 million and will be paid for using SPLOST funds. Construction will take about one year to complete.
