O'Hare West Bypass

The O'Hare West Bypass, also known as Interstate 490, is a proposed toll highway near Chicago that would run along the west side of O'Hare International Airport. The tollway would connect Interstate 294 (I-294, the Tri-State Tollway) to a western access point to the airport. From there, it would continue northward to an extension of the Illinois Route 390 and I-90 (Jane Addams Memorial Tollway). Building the highway would affect the villages of Elk Grove Village, Wood Dale, Itasca and Bensenville.
In December 2009, IDOT finalized the routing of the western bypass. Intermediate interchanges are planned at County Line Road/Franklin Avenue, IL 19, IL 390 (Elgin-O'Hare Expressway), and IL 72.
On August 25, 2011, the Illinois State Toll Highway Authority (ISHTA) approved a $12 billion capital plan, doubling toll rates to fund it. The American Association of State Highway and Transportation Officials approved the Interstate 490 designation in November 2014, contingent on Federal Highway Administration approval.
