Low-Clearance Early Warning Devices

The state of Illinois recently passed legislation requiring IDOT to establish a pilot program to install devices on or near bridges over roadways that warn drivers of low clearances. The aim of this project is to help identify potentially effective devices and technologies that can be installed to help reduce bridge strikes in Illinois. Researchers will examine various technologies and devices used to provide early warning of low-clearance structures as well as their effectiveness. Decreasing the number of bridge strikes reduces costly damage to state property and reduces road and lane closures caused by damaged structures that cannot be immediately repaired.
