This four-mile project will rehabilitate bridges both on and over I-43 in Milwaukee County,from Howard Avenue (just north of the Mitchell Interchange) to the Valley Bridge (just south of the Marquette Interchange).

This stretch of I-43 serves as an important link between the Mitchell Interchange and Marquette Interchange, and is a major regional route for tourism, special events, and commerce. Bridge rehabilitation work is required in this area so this vital link can be maintained, especially in advance of upcoming construction on the Zoo Interchange and Hoan Bridge projects.

This project will rehabilitate 13 bridges on and over I-43 from Howard Avenue to the Valley Bridge in Milwaukee County, including bridge deck overlays/replacements, bridge repair and painting.

We ask for your patience as we undertake several large infrastructure improvement projects planned in this area over the next two years.
