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. 

I-94 West full closure Dec. 19-21
A full freeway closure on westbound I-94 will take place from Friday evening, Dec. 19, through Sunday morning, Dec. 21. During this 31-hour freeway closure, I-94 West from Miller Park Way to the Zoo Interchange will be closed. For more information, download this flier.

Alternate routes to the Milwaukee Regional Medical Campus are:

  1. Exit at the stadium interchange/US 41 and travel north to the Wisconsin Avenue exit, stay in the left lane of the ramp to turn left onto Wisconsin Avenue. Continue west on Wisconsin Avenue to MRMC.
  2. Take the I-894 bypass to US 45 North and exit at Watertown Plank Road. Go east on Watertown Plank Road to MRMC.

Hooray! It's done! Watertown Plank Road Interchange is complete
The new Watertown Plank Road Interchange near Children’s Hospital of Wisconsin is complete! All of the ramps are open, which means all of the Wisconsin Avenue ramps are closed. Crews still are putting the finishing touches on the ramps and roads around Children’s Hospital – and the Core of the Zoo Interchange is just getting started. Please continue to plan ahead, know your route and allow extra travel time.
