Connecticut Department of Transportation’s I-91/I-691/Route 15 Interchange project seeks to reduce traffic congestion and improve safety.  Phase 1 of this project improved traffic flow, enhanced safety, and supported local community connectivity around the I-691/I-91 Interchange in the cities of Meriden and Middletown, contributing to a more resilient local transportation network. The $83.7 million project implemented a wide range of safety improvements including pavement rehabilitation, roadway resurfacing, bridge repairs and replacements, upgraded illumination, enhanced drainage, and new signage. The new sound barrier wall provides noise reduction for the adjacent close-knit neighborhood. These upgrades reduced the risk of crashes, making the surrounding communities safer and more accessible. Pavement and bridge rehabilitation ensure long-term durability and minimize long-term maintenance disruptions to the community. While the first phase of the I91/I691/Route 15 Interchange improvements was fully state funded, it positioned CTDOT to pursue federal Infrastructure Investment and Jobs Act funding for the next phase. The project has made the community safer by significantly reducing the long-term congestion at the I-691 eastbound interchange to I-91 northbound in Meriden to support the mobility of goods via trucks and travelers via buses and private vehicles.
