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).

[13][14] 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.

In 2016, ISTHA sued the Canadian Pacific Railway to request that the United States Surface Transportation Board allow for the construction of the tollway.

[14] In preparation for the interchange at Interstate 90, and the widening of I-90, the Des Plaines over-highway oasis structure was permanently closed on March 16, 2014.

[24] 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.
