The Department of Transportation (CTDOT) is developing plans to upgrade existing traffic control signal equipment or install new traffic control signal equipment to meet current standards at 15 locations in the cities and/or towns of Clinton, Griswold, Groton, Mansfield, Montville, North Stonington, Norwich, Portland, Stonington, and Waterford.  At applicable locations, pedestrian control features (countdown pedestrian indications, accessible pushbuttons, sidewalk ramps) will be upgraded to improve accessibility and pedestrian safety.

It is CTDOT’s policy to keep the public informed and involved when such projects are undertaken. It is important that the community share its concerns with us to assist in the project’s development. At this time, it is anticipated that an informational meeting or formal public hearing will not be necessary. 

The design plans for this project are expected to be completed in May 2025 with a tentative advertising date of July 2025.
