The public is invited to a meeting on the project June 5, 7-8:30 p.m., at St. Barnabas Episcopal Church, 4801 Ravensworth Road in Annandale. Staff from the two agencies will answer questions and share displays at 7; the presentation will begin at 7:30.
The roundabout would be an alternative to a traffic signal, says Terry Yates of VDOT.
According to VDOT, roundabouts improve traffic flow and pedestrian safety. They also reduce fuel consumption and are more cost-effective than traffic signals.
The roundabout, to be installed this summer, will be a temporary, modular structure using recycled composite materials. It would be evaluated by the two agencies for installation, function, and maintenance, such as how snowplows will be able to negotiate the structure next winter.
If there are no problems, it could remain as a permanent structure, Yates says.
VDOT identified the Ravensworth/Jayhawk intersection as a candidate for the pilot project because it meets the thresholds for a traffic signal and a roundabout can be installed there without the need for new pavement, right-of-way approvals, utility relocation, or drainage work.
The roundabout at that location would be similar in scale to a mini-roundabout recently installed by the Town of Vienna at Park and Locust Streets.
