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.

Construction Project Details

WIS 15 Interchange

Work will include reconstructing the existing interchange at I-41 and WIS 15 as a diverging diamond interchange (DDI) to accommodate higher traffic volumes and increase safety. Additional bike and pedestrian accommodations, as well as crash investigation sites, will also be constructed. The southbound exit ramp and northbound entrance ramp at I-41 and WIS 96 will be reconstructed.

Traffic Impacts

I-41 is scheduled to have periodic nighttime freeway closures during WIS 15 bridge construction.

  • Northbound traffic will be detoured from I-41 at WIS 96 to WIS 47.
  • Southbound traffic will be detoured from I-41 at WIS 47 to WIS 96.

WIS 15/County OO/Northland Avenue over I-41 is scheduled to be closed beginning in early 2025.

  • Traffic will be detoured using County CB, WIS 96, and Lynndale Drive.

SB I-41 exit ramp to WIS 96/Wisconsin Avenue (Exit 138) is scheduled to be closed in early 2025.

  • Traffic exiting to eastbound WIS 96 will use WIS 125/College Avenue and Lynndale Drive.
  • Traffic exiting to westbound WIS 96 will use WIS 15 and County CB.

Additional long-term ramp closures can be expected at the WIS 15 interchange in coordination with work occurring at WIS 96.

  • A temporary road will be constructed to maintain access from Southbridge Road to Innovation Court.
  • In the spring of 2025, Mid Valley Drive between Birchwood Road and Quarry Park Drive will be closed for 14 days to complete the realigned Mid Valley Drive.   
  • Short-term lane closures along I-41 can be expected at night. 
  • Access will be maintained to residents and businesses throughout the project.
