Governor Ned Lamont announced on April 27 significant progress in the ongoing Interstate 91, Interstate 691, and Route 15 interchange reconfiguration project in Meriden. The first phase of the project has been completed on time and within budget, while work continues on phase two with an expected completion by 2028. The entire three-phase program is scheduled to finish by 2030.
The project aims to improve a major traffic corridor in central Connecticut, which officials say will help ease congestion for commuters, support the movement of goods across the state, and contribute to long-term economic growth. Phase three began earlier this month with preparations for full reconstruction along the corridor. This stage will focus on new ramps and bridge work intended to reduce congestion and improve traffic flow.
“This project to improve this major traffic corridor in central Connecticut was seriously needed and is focused on supporting the needs of our state’s infrastructure for decades to come,” Governor Lamont said. “By modernizing this critical interchange, we will ease congestion for commuters, improve the movement of goods across our state, and support long-term economic growth. From day one, we committed to delivering these improvements on-time and on-budget, and today’s progress shows we are getting it done for the people and businesses who rely on this corridor every day.”
Connecticut Department of Transportation Commissioner Garrett Eucalitto said crews are working around the clock while maintaining traffic flow: “We are making strong progress across every phase of this project, thanks to crews working day and night to keep construction moving while maintaining traffic flow. As work continues, we urge drivers to slow down, stay alert, and give our crews the space they need to work safely so we can keep this project on track.”
Funding comes from both state resources as well as federal funds provided primarily through the Infrastructure Investment and Jobs Act (Bipartisan Infrastructure Law). The total cost is anticipated at more than $712 million.
Senator Richard Blumenthal said: “I am thrilled to see the progress on this pivotal project move forward on time and on budget… I applaud Governor Lamont and Commissioner Eucalitto for committing to making this interchange safer…” Senator Chris Murphy added: “I’m glad to see state and federal dollars working together…to make our highways safer.” Congresswoman Jahana Hayes also noted that upgrades would ensure safer commutes thanks in part to federal funding.
The first phase included bridge repairs along with additional lanes; phase two focuses mainly on new exit ramps; phase three will bring further ramp expansions designed for smoother travel through one of Connecticut’s busiest interchanges. A labor agreement supports job creation during construction.
