More roundabouts—one-way circular intersections where traffic flows around a center island—are coming to Richfield.
The Richfield City Council approved roundabouts on 66th Street at Lyndale Avenue and Nicollet Avenue on February 24, 2015. The roundabouts will be constructed with the upcoming 66th Street reconstruction project scheduled to begin in 2017.
Roundabouts will keep traffic flowing and offer safety benefits for drivers, bicyclists, and pedestrians. Vehicles entering a roundabout yield to those already in it, providing safe and efficient traffic flow. No more red lights!

Slower speeds are generally safer for pedestrians, and studies show that roundabouts at busy intersections are dramatically safer than stop lights, offering:
- a more than 90% reduction in fatalities*
- a 76% reduction in injuries**
- a 35% reduction in all crashes**

Roundabouts move traffic safely and efficiently by:
- slowing driver speeds
- reducing conflict points
- allowing easy decision-making
Slower vehicle speeds mean:
- Drivers have more time to judge and react
- Older and beginner drivers find intersections safer to navigate
- The severity of accidents is reduced
- Pedestrians are safer
- Traffic is always on the move so there is less delay
- Traffic capacity in the intersection is increased 30 to 50%
- Pollution and fuel use are reduced
- Fewer stops and starts means less noise
- There is no signal equipment to install and repair
Compared to standard instersections, there are fewer conflict points in a roundabout:
(Left) A traditional intersection has 32 conflict points. (Right) A modern roundabout has 16 conflict points. Accidents in roundabouts are typically minor due to slower speeds and indirect contact points.
