💷 Chicago Skyway

Interstate 90 (I-90) in the US state of Illinois runs roughly northwest-to-southeast through the northern part of the state. Entering Illinois at the Wisconsin state line in South Beloit, it passes through the Rock River Valley and the suburbs of Rockford, where it turns eastward, heading towards Chicago through farmland west of the Fox River Valley and through medium-density suburbs west of O'Hare International Airport. After entering through Downtown Chicago, I-90 passes through the heart of the industrial southeast side of Chicago before entering Indiana, crossing the Calumet River on the Chicago Skyway toll bridge.
