Governor Evers approves I-43 North-South project to begin

​​​​Release date: February 7, 2022

To invest in Wisconsin's transportation system, Governor Evers approved $550 million in summer of 2019 to reconstruct and modernize 14 miles of I-43, between the cities of Glendale and Grafton, in Milwaukee and Ozaukee counties. WisDOT has maintained these interchanges, bridges and pavement for over 50 years. The structures and pavement are at the end of their useful life cycle. 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. 

Work is tentatively scheduled to begin the week of February 21, weather permitting. 

What to Expect This Year

Construction in 2022 will focus on expansion and improvements near the Highland Road area north to WIS 60, as well as the County Line Road/Port Washington Road Interchange area. 

  • Work near Highland Road is anticipated to begin the week of February 21.
    • Minor overnight prep work activity will require nighttime single-lane closures along I-43 at the bridge leading up to construction. 
  • Work near the County Line Road/Port Washington Road interchange is anticipated to begin in late February. 

I-43 remains open to two lanes in each direction during peak travel times, but the project requires various closures of adjacent bridges, ramps, and roadways to help facilitate construction. View detailed information​ on project improvements and traffic impacts taking place in 2022.
