Modern roundabouts provide greater safety and traffic flow. Learn why and where MDOT is building them.
A roundabout is a type of circular intersection that has been used in Europe for several decades. In recent years, MDOT has constructed several roundabouts on state trunklines and more are planned.
They keep traffic moving; this decreases emissions and improves fuel economy.
Increase safety because there is no stopping in a roundabout, no left turns across opposing traffic lanes, and all vehicles must maintain similar speeds.
Lane design and pavement markings guide drivers through the intersection.
They force vehicles to slow to a safe speed for the intersection.
Can be landscaped to offer an attractive gateway into a city or other area.
