Project details
This project will deliver a safer and more efficient intersection at Route 28 (Fellsway/McGrath Highway) and Route 38 (Mystic Avenue) in Somerville. Key improvements include a southbound lane drop on McGrath Highway at Broadway to reduce driver conflict points and improve safety. Modern adaptive signal systems will improve real-time traffic flow based on actual conditions. The project also features new pedestrian crossings, widened sidewalks, separated bike lanes, and upgraded curb ramps to enhance accessibility and mobility for all users.
Benefits of the project include increased safety for all users, more predictable traffic patterns with adaptive signals, and support for multi-modal transportation.
