Cotuit Road Modern Roundabout, Sandwich

Massachusetts Department of Transportation
Sandwich, Massachusetts

Known as one of the most hazardous intersections on Cape Cod, the Cotuit Road/Harlow Road intersection was in critical need of safety improvements. The modern roundabout solution was developed through the collaborative Road Safety Audit (RSA) process. The audit brings together local officials, such as police and fire departments, with technical engineering expertise. Having evaluated numerous options, it was clear that the existing roadway layout and traffic flow pointed to the roundabout as the preferred option. Our close collaboration with the reviewing agencies allowed us to advance this federally funded project from start to construction completion in three years. We are pleased to note that the roundabout was completed ahead of schedule and has been welcomed by the Town of Sandwich.
