Highway in Illinois

Interstate 490 (I 490), also known as Richard H. Foley Jr. Honorary Expressway or 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.

I 490 will begin at a partial interchange with I 294 (Tri State Tollway) in Franklin Park, south of O'Hare International Airport. There will be an interchange with Franklin Avenue/Green Street. The tollway will head north before curving westward to briefly parallel the Canadian Pacific Railway before crossing it. Immediately afterwards, the tollway will have an interchange with IL 19 (Irving Park Road). On the western side of O'Hare International Airport, I 490 will have an interchange with IL 390 (Elgin–O'Hare Tollway) at the entrance to a planned western terminal. Continuing north, I 490 will cross over the Canadian Pacific Railway and the Union Pacific Railroad Milwaukee Subdivision and have an interchange with IL 72 (Touhy Avenue) before ending at a trumpet interchange with I 90 (Jane Addams Memorial Tollway) in Des Plaines.

In December 2009, the Illinois Department of Transportation (IDOT) finalized the routing of the western bypass. Intermediate interchanges are planned at County Line Road/Franklin Avenue, IL 19, IL 390, and IL 72. On August 25, 2011, the Illinois State Toll Highway Authority (ISHTA) approved a $12 billion (equivalent to $ in ) capital plan called Move Illinois, which seeks to improve toll roads under their jurisdiction; the authority doubled toll rates to help fund it. The bypass is also part of the EOWA project. On October 6, 2014, IDOT submitted an application to the American Association of State Highway and Transportation Officials (AASHTO) for the creation of the new I 490 designation. AASHTO approved the I 490 designation on November 20, 2014, contingent on Federal Highway Administration (FHWA) approval. Construction on the interchange with I 90 began on September 12, 2018; the interchange was scheduled to be finished in 2023, but that has since been pushed out to 2025. The project is planned to be finished in 2026. The over highway oasis structure began to be deconstructed immediately, but the gas stations and gas station stores remained open. These businesses were eventually closed on December 14, 2018. The oasis, which opened on June 24, 1959, was the second oldest of the five original tollway oases in Illinois. The gas station buildings were finally demolished in April 2019, and the new bridge decks over I 90, placed almost exactly where the oasis was previously located, were installed in June 2019.
