I-90 uses several sections of the [[Illinois Tollway]] system as it traverses the [[Northern Illinois|northeastern corner]] of the state, primarily in the [[Chicago metropolitan area]]. It enters the state from Beloit, Wisconsin, and remains concurrent to I-39 and [[U.S. Route 51|US&nbsp;51]] on the [[Jane Addams Memorial Tollway]] through the eastern outskirts of [[Rockford, Illinois|Rockford]], where the highways split off. I-90 continues on the tollway as it follows [[U.S. Route 20|US&nbsp;20]] southeast through [[Belvidere, Illinois|Belvidere]] and [[Elgin, Illinois|Elgin]] in the [[Fox Valley (Illinois)|Fox Valley]].<ref name="ILTollway-Map">{{cite map |date=January 2020 |title=Illinois Tollway 2020 Complimentary Map |at=[https://www.illinoistollway.com/documents/20184/145046/TollwayMap_01_29_2020-SideB.pdf Chicago and Vicinity] inset |url=https://www.illinoistollway.com/documents/20184/145046/TollwayMap_01_22_2020-SideA.pdf |scale=Scale not given |location=Downers Grove |publisher=[[Illinois State Toll Highway Authority]] |accessdate=November 29, 2021 |archive-date=November 30, 2021 |archive-url=https://web.archive.org/web/20211130073626/https://www.illinoistollway.com/documents/20184/145046/TollwayMap_01_22_2020-SideA.pdf |url-status=live }}</ref>

The tollway cuts through the northwestern suburbs of Chicago, where it intersects [[Interstate 290 (Illinois)|I-290]] in [[Schaumburg, Illinois|Schaumburg]] and passes the north side of [[O'Hare International Airport]]. On the east side of the airport in [[Rosemont, Illinois|Rosemont]], I-90 intersects [[Interstate 294|I-294]] and [[Interstate 190 (Illinois)|I-190]], the latter of which serves the airport's passenger terminals and marks the end of the tollway.<ref name="ILTollway-Map"/> The freeway, now named the [[Kennedy Expressway]], travels through northwestern Chicago, where the [[Blue Line (CTA)|Blue Line]] of the [[Chicago "L"|"L" rapid transit system]] runs in the median and serves several stops.<ref name="Tribune-BlueLine">{{cite news |last=Hilkevitch |first=Jon |date=December 5, 2013 |title=O'Hare Blue Line to stay open during 4-year renovation |url=https://www.chicagotribune.com/news/ct-xpm-2013-12-05-chi-4year-492m-blue-line-project-to-be-announced-today-20131205-story.html |work=Chicago Tribune |accessdate=November 29, 2021 |archive-date=October 9, 2022 |archive-url=https://web.archive.org/web/20221009230610/https://www.chicagotribune.com/ |url-status=live }}</ref> I-90 turns southeast and is rejoined by I-94 in [[Irving Park, Chicago|Irving Park]], where it gains a set of [[reversible lane|reversible express lanes]] that travel for {{convert|6.2|mi|km}} toward the [[Near West Side, Chicago|Near West Side]].<ref>{{cite news |last=Hilkevitch |first=Jon |date=August 22, 2011 |title=Drivers frustrated by Kennedy express lanes |url=https://www.chicagotribune.com/autos/ct-xpm-2011-08-22-ct-met-getting-around-0822-20110822-story.html |at=sec. 1, p. 4 |work=Chicago Tribune |accessdate=November 29, 2021 |archive-date=November 30, 2021 |archive-url=https://web.archive.org/web/20211130071337/https://www.chicagotribune.com/autos/ct-xpm-2011-08-22-ct-met-getting-around-0822-20110822-story.html |url-status=live }}</ref>
