The Connecticut Department of Transportation (CTDOT) has begun construction on a major project on I-95 in West Haven to replace two aging bridges and improve traffic flow in the area.
The bridges, which are each more than 70 years old, carry I-95 over First Avenue and the Metro-North Railroad train tracks. The new structures are designed to have a minimum service life of 75 years, significantly improving long-term safety and reliability.
In addition to replacing the bridges, the project includes extending the southbound lane from Exit 44 to create a continuous travel lane, which will ultimately serve as an exit-only lane for Exit 43. The goal of these improvements is to reduce congestion, enhance traffic flow, and improve safety in the region.
The $136.5 million project is expected to be completed in phases by year-end 2027.
For most of 2025, traffic is not expected to be disrupted from this project because the initial work includes construction on the foundation for the new bridges on the ground level at 1st Avenue and at the railroad crossing underneath the highway.
Later in 2025, the northbound entrance ramp at Interchange 43 will close, with a detour routed through nearby state roads. The project will progress in stages through 2027, with three lanes of traffic maintained in each direction during daytime hours.
