Roundabouts

For more information about the upcoming roundabouts at Plainfield and Hunt Road, please click here.

The City's second roundabout opened to traffic in December of 2018. It is located at the new Plainfield Road and Parkview Drive intersection, which is the entrance to the Daventry neighborhood. This roundabout will accommodate two lanes of traffic, as well as pedestrians and bicyclists. The City’s first roundabout, at Malsbary and Alliance Road, opened in 2017 and has been a success.

A roundabout is a circular intersection in which traffic flows counterclockwise around a center island. There are no traffic signals or stop signs in a roundabout. According to the U.S. Department of Transportation, roundabouts improve safety, reduce congestion, reduce pollution, save money, and are functional. When compared to other intersections, roundabouts result in a 90% reduction in fatalities, 76% reduction in all injuries, and a 35% reduction in crashes.

In addition to keeping drivers safe, roundabouts are also easy to maneuver and reduce congestion. Drivers only have to watch for traffic from the left, and can enter the roundabout when there is  adequate space available. Once in the roundabout, drivers have the right-of-way, so they will not have to stop or yield to exit. Any delay that could take place in a roundabout is shorter than the amount of time spent waiting at a traffic light.

 There are just a few guidelines to remember when driving through a roundabout:

• Slow down.
• If there's more than one lane, use the left lane to turn left, the right lane to turn right, and all lanes to go through, unless directed otherwise by signs and pavement markings.
• Yield at the entry to circulating traffic.
• Stay in your lane within the roundabout and use your right-turn signal to indicate your intention to exit.
• Always assume trucks need all available space — don't pass them!
• Clear the roundabout to allow emergency vehicles to pass.
