I-39/90 Expansion Project

Illinois state line to Madison, Dane and Rock Counties

Public meeting for upcoming I-39/90 work in Janesville area

Posted: August 10, 2017

The Wisconsin Department of Transportation (WisDOT) is preparing to reconstruct and expand approximately 12 miles of Interstate 39/90 from Hart Road near Beloit north to the I-39/90 and US 14 interchange (Exit 171B) in Janesville. Work is tentatively scheduled to start in September and will be completed in spring of 2020 (weather-permitting).

Throughout construction, I-39/90 will remain open with two lanes of traffic in each direction. Work will begin on the northbound Interstate lanes and northbound traffic will be shifted over to temporary lanes onto the southbound side of I-39/90 during construction. When the I-39/90 northbound expansion is complete within these limits, both northbound and southbound motorists will be shifted to the new northbound pavement as crews reconstruct and expand the existing I-39/90 southbound lanes.

During construction, local roadways under I-39/90 in Janesville may be temporarily closed for bridge work. Advanced notice of these temporary closures will be announced to the media and on the project’s website.

You are invited to attend a Public Meeting to learn more about this project, including the planned construction staging and schedule, and how to stay informed during the operations. Exhibits showing the planned improvements will also be on display. WisDOT representatives will be available to discuss the project on an individual basis.
