I-43 Rehabilitation (Brown St. to Capitol Dr.) - Milwaukee County

​Project location

Project overview

In providing access to neighborhoods, manufacturers, commuters and tourists within the Milwaukee metropolitan area, and connecting Milwaukee to other areas including northern Illinois and Green Bay, I-43 is a critical interstate link not only for Southeast Wisconsin, but the entire state. The corridor connects access points throughout the city, serves as a gateway to popular tourist locations, and links major industrial centers throughout the region.

​​Today, I-43 carries nearly 160,000 vehicles each day through the project area. Traffic is projected to grow another 15 percent over the next thirty years.

​The pavement and bridges in the project corridor, from Brown Street to Capitol Drive,​​ need major rehabilitation or replacement.​ All planned and recommended modifications will stay within the existing freeway right of way.
