Whether you love them or hate them, more roundabouts are coming to Connecticut. WATCH HERE WATCH HEREAccording to the Connecticut Department of Transportation, there are currently more than 30 roundabouts on state and local roads in Connecticut, with more than a dozen planned or under construction. A study of five roundabouts found an 81% reduction in severe crashes and a 44% reduction in total crashes, according to CTDOT. Situations like that are part of the reason why the Naugatuck Police Department created a video with a tutorial on proper traffic flow. “The state wanted a roundabout because they are safer, more efficient, better for traffic flow,” Hess said.
