Interstate 490 (I-490), also known as the 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.[1] 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.[2] Building the highway will affect the villages of Elk Grove Village, Wood Dale, Itasca, and Bensenville.[3] The route will run through the 1979 American Airlines Flight 191 crash site, the deadliest aviation accident in US history.[4]
