To reduce traffic backups and keep traffic moving at the intersection of Peachtree Corners Circle and Medlock Bridge Road, the “T” intersection will be converted to a roundabout.
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. The decision to install a roundabout rather than a traffic light was made due to several factors including increased safety. Studies show that roundabouts are safer than signalized intersections as it reduces conflict points and prevents 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.
“The roundabout will be a big improvement for this busy intersection, especially during rush hour,” said Mayor Mike Mason. “The pedestrian safety features are certainly timely as we expect foot traffic to increase once the city’s Town Center opens next year.”
While the construction costs for roundabouts and signalized intersections are similar, the cost to maintain a roundabout is considerably less. The project is funded through the City’s SPLOST funds. The final construction cost is about $1.2 million. Construction is expected to be complete by the end of 2019.
