KOA is developing complete plans, specifications, and estimates (PS&E) for traffic calming improvements on Randolph Avenue and St. Clair Street, between Bristol Street and Baker Street. Our design work includes parallel and angled/diagonal on-street parking, a single-lane roundabout with a central island and raised splitter islands, crosswalks, ADA/pedestrian curb ramps, a street lighting plan, rectangular rapid-flashing beacons (RRFB), speed humps/cushions, and minor traffic signal modifications.
