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.
