Interstate 490 Illinois


Interstate 490 in Illinois is part of a $3.4 billion investment to improve connectivity to Chicago O’Hare International Airport (ORD) and adjacent transit facilities, distribution centers and freight transportation hubs. Being developed by the Illinois Tollway Authority in conjunction with the Illinois Route 390 Tollway, the I-490 Tollway is part of 17 miles of new expressway built to both accommodate traffic around the west side of O’Hare Airport and to provide access to the airport.1

The Illinois Route 390 Tollway was completed in November 2017.1 It extends west from IL 83 (Busse Road) at the city of Wood Dale to U.S. 20 at the village of Hanover Park. Construction of IL 390 included converting the previous Elgin O’Hare Expressway west from I-290 (Eisenhower Expressway) to U.S. 20 into a toll road.
