Wrong Way Detection System Inspection and Testing on I-91 in New Haven and North Haven

The Connecticut Department of Transportation (CTDOT) is announcing wrong way detection system inspection and testing will take place on I-91 northbound and southbound in New Haven at exit 3 and Route 40 southbound in North Haven at exit 1. This project is scheduled to occur Tuesday, October 14 to Wednesday, October 15, 2025.

These bi-annual inspections are routine and ensure the Wrong Way Detection Systems remain up to standard.

The Wrong Way Detection System uses video cameras to detect vehicles that are traveling in the wrong direction. If a vehicle is detected, wrong way signs outlined with multiple sets of red lights are activated and begin flashing to alert the driver they are traveling in the wrong direction. Additionally, the system alerts the CTDOT Highway Operations Center and local State Police Troop barracks in real-time, allowing staff to monitor the activities of the wrong way driver on the ramp.

The work is being performed by State Forces.
