Crews from the Connecticut Department of Transportation (CTDOT) have conducted overnight inspections of New Haven’s Heroes Tunnel on state Highway 15/Wilbur Cross Parkway in recent days as they prepare for a $150 million renovation project slated to begin in 2028. The inspections, which started late on Monday, Sept. 22, 2025, and were planned to last through early on Sept. 26, were done to help shape designs for the tunnel’s overhaul to improve safety and travel, Eva Zymaris, a CTDOT spokesperson, told the Greenwich Time. The tunnel, a critical link along Conn. 15 that carries about 74,000 vehicles per day through West Rock Ridge in New Haven, has been wearing down in recent years, the Greenwich Time learned. The latest plans call for repairs to the tunnel liners, updated ventilation and fire-protection systems, better lighting and new signs to guide both drivers and pedestrians. Currently, the project is in the design and environmental review phases.
