Web Version     CTDOT Celebrates National Roundabouts Week Posted on September 18 , 2026 During National Roundabouts Week, the Connecticut Department of Transportation (CTDOT) is highlighting the critical role modern roundabouts play in enhancing roadway safety. Circular in shape, a modern roundabout is a type of intersection that moves traffic one way in a counterclockwise direction around a center island. Its channelized approaches force vehicles to slow down and yield to crossing pedestrians or bicyclists and traffic already in the circle.

In Connecticut, a study of five roundabouts found an 81% reduction in severe crashes and a 44% reduction in total crashes. “Constructing modern roundabouts has consistently shown a reduction in both the frequency and severity of crashes. We support building roundabouts where appropriate to improve traffic flow and safety for all road users,” said Connecticut Department of Transportation Commissioner Garrett Eucalitto. “If your city or town is considering a roundabout project, we encourage you to reach out. Our team stands ready to provide guidance and support every step of the way.” In Granby, a roundabout at Route 10, Route 202, and Notch Road opened in 2020. The project was designed to improve safety at the intersection. Data shows a 60% reduction in crashes and 83% reduction in injuries since construction was completed. “We would go there a number of times a year for car accidents of varying severity levels,” said Lost Acres Fire Department Chief Tim Weber. “Since then, it hasn’t been an issue.” Rules of the roundabout: Slow down. Going slower provides more time to make decisions and be better prepared to yield to other road users. It also helps reduce the likelihood and severity of crashes. Look around. When approaching the roundabout, look for signs and markings about speed and lane choice. Be ready to yield. Drivers entering the roundabout must yield to traffic in all lanes of the roundabout, not just in the lane closest to them. Bicyclists should enter the roundabout with vehicles or dismount to use sidewalks and crosswalks. There are approximately 40 roundabouts on state and local roads in Connecticut, with more than a dozen planned or under construction. The CTDOT Roundabouts Committee is comprised of experienced engineers who assist with the planning, designing, and constructing of roundabouts around the state – serving as a resource for Connecticut cities and towns. The Committee reviews roundabout concepts, advises on good design practices, and can help answer questions on size, suitability, materials, pavement markings, and more.
