I-39/90 Expansion Project

Illinois state line to Madison, Dane and Rock counties

WIS 59 interchange

The I-39/90 and WIS 59 interchange, near Edgerton, was reconfigured into a diamond interchange with three roundabouts in order to improve safety, efficiency and reduce overall congestion in the area.

WisDOT created a narrated animation video, which shows three major movements at the interchange and demonstrates how to safely navigate the new interchange. You can also download and print the WIS 59 interchange handout. PDF
