Kennedy Expressway Reversible Lanes | Illinois Department of Transportation

Knight designed the innovative system of gates and remote controls to the center lanes of the Kennedy Expressway in Chicago, allowing for traffic flow in either direction depending on traffic needs. Typically operated to meet traffic demand for rush hour traffic, they can also be used to manage incidents, control traffic at major events and direct traffic in the event of natural disasters. First designed nearly 20 years ago in direct response to a critical operational and safety challenge at IDOT, Knight is currently working to enhance and upgrade the system with the integration of new technologies and advancements in Intelligent Transportation Systems.
