US 41 Interstate Conversion - Schedule

Current (this year)

Federal grandfathering legislation that was needed to maintain the current weight limits on US 41 when it is converted to a Interstate was signed into law on Dec. 17, 2014. This legislation paved the way for Wisconsin Department of Transportation (WisDOT) to complete the paperwork required to convert US 41 to an Interstate.

  • April 7, 2015 - I-41 officially added to Interstate System by Federal Highway Administration  
  • April 14, 2015 - Construction bid letting for signing plans
  • Spring 2015 - Signing installation begins
  • November 2015 - Signing installation complete
