I-91/i-691/route 15 Reconstruction: Latest Status, Cost & Timeline 2026
The i-91/i-691/route 15 reconstruction is a major $500M highway interchange redesign spanning 3.5 mi in Meriden, Connecticut, connecting key regional interstate corridors. Managed by CTDOT under a federal-state formula funding model supported by IIJA federal grants, this brownfield infrastructure endeavor replaces outdated weave sections and sharp ramp geometry to improve regional mobility and safety across Central Connecticut. Official plans detail the realignment of major interchanges between Interstate 91, Interstate 691, and Route 15 (Wilbur Cross Parkway). The project's environmental review established critical noise barrier mitigations, geometric reconfigurations, and bridge rehabilitations within the existing highway right-of-way. According to official project documentation, the preliminary alignment improvements reduce severe traffic bottlenecks and modernizes operational capacity for over 100,000 daily commuters. Phased construction activities are actively underway, with the final project completion date expected by 2029, delivering enhanced freight efficiency and long-term corridor resilience.
