2024 I-41 Construction Map

The I-41 Project began construction in early spring 2024. The project will reconstruct and expand 23 miles of I-41 from four lanes to six lanes between WIS 96 (Wisconsin Avenue) in Appleton and County F (Scheuring Road) in De Pere. 

The project will reconstruct the system interchange at the junction of I-41 and WIS 441, reconstruct or improve the nine existing service interchanges on this corridor, and construct a new service interchange at I-41 and Southbridge Road. 

As part of this project, a new building will replace the Wrightstown Safety and Weight Enforcement Facility (SWEF) with a combined Wrightstown Post and SWEF for the Northeast Region.

I-41 Mainline

Work will include expanding 23 miles of I-41 mainline to 6 travel lanes, constructing auxiliary lanes along I-41 between closely spaced interchanges, and constructing collector-distributor roads between Ballard Road and WIS 441. Four lanes of traffic will continue to remain open on the mainline during peak hours.
