Zoo Interchange updates

The Zoo Interchange project touches the cities of Milwaukee, Wauwatosa and West Allis and will cover about nine miles of freeway leading to and through the actual interchange. The street and highways surrounding the Milwaukee Regional Medical Complex, which includes Children's Hospital of Wisconsin, are impacted. Check here for updates and resources from the Department of Transportation to help you throughout this long-term construction project.

Work in the surrounding area is under way. You may experience delays due to lane closures, utility work or detours. To ensure you arrive to your appointments on time, be sure to check the latest traffic information before leaving home.
