Interstate 490 (Illinois)

Interstate 490 (I-490), also known as O'Hare West Bypass and Western O'Hare Beltway, is an electronic toll highway and a beltway that is currently under construction near Chicago, Illinois; it will run along the west side of O'Hare International Airport. The tollway will connect I-294 (Tri-State Tollway) to a western access point to the airport. From there, it will continue northward to an extension of Illinois Route 390 (IL 390, formerly known as the Elgin-O'Hare Expressway) and I-90 (Jane Addams Memorial Tollway). The O'Hare Western Bypass is part of the Elgin–O'Hare Western Access (EOWA) project. Building the highway will affect the villages of Elk Grove Village, Wood Dale, Itasca, and Bensenville. The route will run through the 1979 American Airlines Flight 191 crash site, the deadliest aviation accident in US history.
