Project overview

In 2005, 142 miles of US 41, from Milwaukee to Green Bay, were identified by the federal government for inclusion in Wisconsin’s Interstate Highway System. This project will convert 130 mile segment of US 41 from a US highway to an Interstate.

Designating the highway as an Interstate is expected to bring economic growth from Milwaukee to Green Bay, increase the safety of the road, create a corridor identity, and bring broader benefits to the state of Wisconsin.

Planning started in 2007.

Status/phase

A long-term planning study is underway with the potential for future construction.

• Design of signing improvements anticipated to start in 2013
• Installation of Interstate signs anticipated to start in 2014
