The Department of Public Works announced intersection traffic signal improvements underway by the State of Connecticut Department of Transportation in town. New traffic control devices are being installed this summer at the intersection of Main Street with Bridge Street and Elm Street, at the intersection of Main Street and Case Avenue, and at the intersection of North Main Street and Wetmore Avenue. Poles will be replaced as will the traffic lights and sensors. Additionally, improvements will be made to the crosswalk signals, crosswalk ramps, and the curbing in those areas. Crosswalks will be repainted, too.
