I-Pass (stylized as I-PASS) is the electronic toll collection system utilized by the Illinois State Toll Highway Authority (ISTHA) on its toll highways that launched on November 18, 1993, with the opening of Interstate 355 (Veterans Memorial Tollway). It uses the same transponder as the E-ZPass system used in the Northeastern US, the Chicago Skyway, and the Indiana Toll Road, along with the Indiana State Road 912 (Cline Avenue) Indiana Harbor and Ship Canal bridge.
