JOHNS CREEK, Ga. – The Johns Creek City Council got a look at the plans for the Bell Road-Boles Road roundabout.
The project has 100 percent federal funding from the Federal Highway Adminstration’s Roundabout Program, said Public Works Director Tom Black.
The project was chosen to relieve the traffic congestion at the Bell-Boles intersection.
The roundabout project also includes landscaping, lighting sidewalks and multi-use trails.
Another part of the project is a 4-acre tract of land that was purchased to allow the roundabout to be constructed without interrupting traffic during construction.
The remaining 2.5 acres would be used as a pocket park.
This project will be advertised for construction in June and awarded in July pending Georgia Department of Transportation approval. Construction should take about nine months, Black said.
The Federal Highway Administration is funding these roundabout projects to study the efficiency and other benefits of these traffic solutions.
• Determine the impact on crash severity at locations where roundabouts have been installed.
• Observe roundabout operations, including truck maneuvers.
• Identify the key geometric configurations and site characteristics that influence safety, performance and return on investment.
According to the Federal Highway Administration, roundabouts are increasingly recognized as an intersection control strategy that can fulfill multiple performance goals related to traffic operation and safety.
They have also shown to exhibit sustainability, livability, economic development and other goals. Some transportation agencies have recently constructed or approved the use of a series of roundabouts on an arterial road rather than the traditional solution of coordinated signalized intersections. The performance of functionally interdependent roundabouts on arterial roads will allow the collection of comparison data with signalized intersections.
Driving single-lane roundabouts
• As you approach a roundabout, you will see a yellow “roundabout ahead” sign with an advisory speed limit for the roundabout.
• Slow down as you approach the roundabout, and watch for pedestrians in the crosswalk.
• Continue toward the roundabout and look to your left as you near the yield sign and dashed yield line at the entrance to the roundabout.
• Yield to traffic already in the roundabout.
• Once you see a gap in traffic, enter the circle and proceed to your exit. If there is no traffic in the roundabout, you may enter without yielding.
• Look for pedestrians and use your turn signal before you exit, and make sure to stay in your lane as you navigate the roundabout.
