US 41 Interstate Conversion - Need/purpose

Logo - US 41 Interstate Conversion
Up to 150,000 vehicles per day use the US 41 corridor. Interstates carry almost 18 percent of the state’s vehicle traffic each year.

Why is this project needed?

The federal Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), enacted in 2005, designated the US 41 Corridor as a future Interstate route.

Project will convert US 41 from a US highway to an Interstate.

Project benefits

Designating the highway as an Interstate is expected to:

  • Bring economic growth along the newly designated corridor
  • Increase the safety of the road for people and vehicles
  • Create a corridor identity
  • Bring broader benefits to the state of Wisconsin
