Governor Evers approves project on southbound I-39 in Portage County

​​Project includes resurfacing highway, replacing or repairing culverts

Release date: July 21, 2022

To invest in Wisconsin's transportation system, Gov. Tony Evers has signed a $7.62 million contract with Mosinee-based prime contractor American Asphalt of Wisconsin for a resurfacing project on southbound I-39 in Portage County from the Waushara County line to Birch Drive south of Portage. Construction is scheduled to start Monday, Aug. 1.

The pavement on this segment of southbound I-39 is deteriorating. To address this and other needs, the Wisconsin Department of Transportation project will:

  • Remove a portion of the existing pavement and place new asphalt pavement.
  • Replace or repair culvert pipes.
  • Upgrade guardrail to meet current standards.

During construction, southbound I-39 will remain open to traffic, but motorists can expect single-lane closures and width restrictions. Work on the on- and off-ramps at the I-39 interchanges at County W and County D will result in overnight closures.

Construction is scheduled for completion in late October. The schedule is weather dependent.
