I-39/90 Expansion Project

Illinois state line to Madison, Dane and Rock counties

I-39/90 Project completion advanced to 2021

Posted: February 5, 2018

The I-39/90 Expansion Project is now scheduled to be completed in fall 2021 – one year ahead of schedule!

Governor Walker made the announcement in his recent annual State of the State address. The Governor cited that by utilizing the current budget and savings, WisDOT will be advancing $32.7 million of the I-39/90 project work into state fiscal year 2018. This advancement puts the I-39/90 Project on track to complete lettings one year ahead of schedule, in fiscal year 2020, and Interstate construction to be completed in fall 2021. This includes the entire I-39/90 project with the exception of the I-39/90 and US 12/18 (Beltline) Interchange, which is currently undergoing environmental analysis.

This advancement does not impact the 2018 construction schedule. Construction timelines for I-39/90 projects in your area can be found at projects.511wi.gov/i-39-90/schedule under North, Central and South segments.
