SLR wins ACEC CT Merit Award for Colt Highway Roundabout Project

SLR has been honored by the American Council of Engineering Companies of Connecticut (ACEC-CT) with a 2025 Merit Award for Engineering Excellence for the Colt Highway Roundabout Project in Farmington, CT. This is the second award SLR has received for this project, the first being an ACE Award in Municipal Achievement in 2024.

SLR was hired by the Town of Farmington to provide design services for a roundabout project at the intersection of State Route 531 and Colt Highway in Farmington, Connecticut to alleviate congestion and enhance safety at the busy intersection. The subject intersection, previously all-way stop controlled, is located just east of the University of Connecticut Health Center (UCONN Health) campus and serves a significant amount of traffic carrying over 15,000 vehicles daily.

About the Colt Highway Roundabout Project

The project involved the design and preparation of contract documents for a 130-foot diameter single lane roundabout with a mountable truck apron, and a right turn lane on the eastbound approach to alleviate queuing on the South Road Bridge over I-84 to the west of the intersection. Capacity analysis using the VISSIM traffic simulation software was employed to vet the roundabout improvements and geotechnical information was obtained and analyzed to inform the pavement design. Accommodations for pedestrians were a key design consideration for the project and sidewalks with ADA ramps and pedestrian refuge areas were provided on all legs of the roundabout and the sidewalk along Colt Highway and extended to the new Connecticut Department of Transportation Park and Ride lot.
