I-39/90 Expansion Project

Home » Community » I-39/90 Expansion Project

The Wisconsin Department of Transportation (WisDOT)

is overseeing a major reconstruction and expansion project in south-central Wisconsin. The I-39/90 Project extends approximately 45 miles along Interstate 39/90 from the Illinois state line to the US 12/18 interchange near Madison.

In order to address safety and congestion concerns, WisDOT will:
  • Reconstruct and expand I-39/90 from four to six lanes and reconfigure 11 interchanges.
  • Expand the Interstate to eight lanes (four lanes in each direction), from WIS 11 (Avalon Rd.) north to the WIS 26 interchange, to accommodate projected traffic increases.
