ODOT Interstate Wrong-Way Sensor-Activated Signage


Sensor–activated light–up signs were installed on I–71 ramps from Mason–Montgomery Rd. to the Lytle Tunnel to help prevent crashes caused by wrong–way drivers. Local police are alerted once a driver passes the sensors placed on the light–up signs. A second set of signs with sensors was also installed to alert ODOT's TMC to dispatch additional emergency response vehicles.
