Construction Continues On Interchange Connection For New I-490 Tollway On The Jane Addams Memorial Tollway (I-90)

Traffic shifts scheduled to begin this week on I-90 as part of new interchange work

Construction on the new, full-access interchange that will connect the new I-490 Tollway to the Jane Addams Memorial Tollway (I-90) in Des Plaines is scheduled to start for the 2019 construction season this week with traffic shifts on I-90.

Electronic message signs and construction signage will be put in place in advance to alert drivers to the traffic shifts.

During the week of March 25, two nights of overnight lane closures on I-90 between Elmhurst Road and Mount Prospect Road will be scheduled to shift traffic in both directions to the left. Each direction will require one night of closures to complete the traffic shift. All work is weather dependent.

In addition, as part of 2019 construction, the ramp carrying traffic from southbound Elmhurst Road to eastbound I-90 is scheduled to close with a posted detour for several weeks during the summer.

Work on the new I-490/I-90 Interchange in 2019 will include the construction of new collector-distributor roads along I-90, retaining walls and barrier walls and drainage and utility work.

The new I-490/I-90 Interchange will consist of four ramps, including a ramp bridge over I-90 connecting westbound I-90 to I-490, constructed west of Mount Prospect Road and will provide full access between the two Tollways. In addition, the I-490/I-90 Interchange Project will also include construction of a new multi-span bridge that will carry I-490 over the Metropolitan Water Reclamation of Greater Chicago’s Touhy Avenue Reservoir south of I-90. The new interchange is scheduled to be complete in 2023.

The new I-490 Tollway, coupled with the Illinois Route 390 Tollway which was completed in 2017, will connect businesses and communities with one of the nation’s busiest airports, transit facilities, major freight transportation hubs, distribution centers and multiple interstate highways including the Jane Addams Memorial Tollway (I-90) and the Central Tri-State Tollway (I-294).

Designed to accommodate access into the O’Hare International Airport, the two new cashless Tollways include 17 miles of new roads with 15 new or improved interchanges. The new I-490 Tollway will be built to carry north-south traffic around the western border of O’Hare and provide access to the airport. The Illinois Route 390 Tollway currently carries east-west traffic between Lake Street (Illinois Route 20) and Illinois Route 83 and will include an interchange connection to the new I-490 Tollway.
