Wisconsin DOT

Save the Date

Learn more about the I-43 North-South project from Glendale to Grafton at a WisDOT Public Involvement Meeting on Wednesday, January 22, 2020 from 4:00 pm to 7:00 pm at Nicolet High School. Meeting is an open house format. You are welcome to attend anytime between 4:00 pm to 7:00 pm.

Project overview

The I-43 North-South Freeway is among the busiest routes in Wisconsin and is a critical Interstate link between southeast Wisconsin and the entire state. I-43 provides access to manufacturers, merchants, commuters and tourists within southeast Wisconsin, the Milwaukee metropolitan area, and other areas including Green Bay, Sheboygan, Manitowoc and Chicago. WisDOT has maintained and rehabilitated the ramps, bridges, pavements and other structures on I-43 for 50 years. The North-South Freeway has exceeded its design life and it is no longer economical to maintain.

This project includes the expansion of I-43 from four to six lanes, the reconstruction of five existing interchanges along the corridor, and the replacement of the Union Pacific railroad bridge over I-43 in Glendale. The project also includes the expansion of a section of Port Washington Road in Glendale from two lanes to four lanes. 

The purpose of the project is to address:

  • Emerging pavement and structural needs
  • Safety issues
  • Design deficiencies, including clearance at bridges, visibility, and merging and weaving distances
  • Existing and projected traffic volumes
  • Purpose and need document

This design will evaluate:

  • Replacing deteriorating pavement and bridges
  • Reducing congestion and improving safety
  • Providing efficient freeway operations
  • Improving or replacing existing interchanges
  • Proposed new interchange at Highland Road
  • Minimizing impacts to natural and built environments

Congestion and crashes

I-43 carries 49,000 vehicles per day south of WIS 60 and 85,460 vehicles per day north of Silver Spring Drive. There is regular and significant congestion in the corridor today. Future projections show traffic growing to 65,000 vehicles per day south of WIS 60 and 112,500 vehicles per day just north of Silver Spring Drive by 2040.

Schedule - Current/Future:

  • Construction is likely to begin in 2022, pending the availability of funding.
