Interstate 91 Interchange Improvement Project in Connecticut, USA: New Ramp to Open in May, Total Cost Exceeds $712 Million

en.Wedoany.com Reported - Connecticut Governor Ned Lamont announced on April 27, 2026, that significant progress has been made on the interchange improvement project for Interstate 91, Interstate 691, and Route 15. The first phase has been completed on time and on budget, the second phase continues to advance, and the third phase has officially commenced.

The announcement was made at a press conference for the newly constructed ramp in Meriden, which leads from the new northbound Route 15 across the I-91 bridge to East Main Street, scheduled to open to traffic on May 1, 2026. The first half of the bridge has been completed, and the second half will be built in the next phase. The second phase, underway for two years, remains on track for completion by 2028, and the entire three-phase interchange improvement project is expected to be finished by 2030.

Early work on the third phase of the interchange improvement began in April, as construction crews prepare the corridor for a full reconstruction, including nighttime operations to maintain traffic flow. This phase will focus on the southbound side, adding dual-lane ramps and reconfiguring key connections, with major bridge work scheduled to begin late this summer.

Governor Lamont stated, "The interchange improvement project to enhance this major transportation corridor in central Connecticut is necessary to support the state's infrastructure needs for decades to come. By modernizing this critical interchange, we will ease congestion for commuters, improve the movement of goods throughout the state, and support long-term economic growth."

The project is managed by the Connecticut Department of Transportation. Funding comes from a combination of state and federal resources: the first phase cost $83.7 million, fully state-funded; the second phase is supported by $50 million in state funding and $200 million in federal funding; the third phase is approximately 80% federally funded and 20% state-funded. The total cost of all three phases is expected to exceed $712 million. Federal funding primarily derives from the 2021 Infrastructure Investment and Jobs Act.
