I-39/90 Expansion Project

Illinois state line to Madison, Dane and Rock counties

WIS 59 interchange

As part of the I-39/90 Expansion Project, the Wisconsin Department of Transportation (WisDOT) will reconstruct the I-39/90 and WIS 59 interchange, near Edgerton, 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
