To the west, the ITR connects to the Chicago metropolitan area via the Chicago Skyway, and to the east, it provides connections to the Ohio Turnpike. The facility provides six lanes for 13 miles at the western end and four lanes for the remainder of the facility. Electronic tolling was introduced in 2008, and the ITR is designated part of Interstate 90 and also Interstate 80 over the eastern section leading into Ohio.
