Zoo Interchange Project Information

The Zoo Interchange project touches the cities of Milwaukee, Wauwatosa and West Allis and will cover about nine miles of freeway corridor leading to and through the actual interchange. We will post updates and other resources from the Department of Transportation to this page to assist you during the construction.

Call 1-800-ZOO-0003 24/7 for up-to-date information on getting to Froedtert Hospital.

Milwaukee Regional Medical Center remains accessible from all directions during the week of July 7. Note that these closures are weather dependent and subject to change.

Full I-94 Eastbound/Westbound Closure — July 18-21, 2014

A full freeway closure of Interstate-94 eastbound and westbound at Highway 100 will take place from Friday, July 18, at 11 p.m., through Monday, July 21, at 5:30 a.m.. During this 54-hour closure, the freeway will be closed to traffic in both directions as crews work to install a new railroad bridge. The map below shows local alternate routes for motorists to use during the closure.

Traffic is expected to be heavy, and backups will occur. If your travel plans include I-94 eastbound or westbound, we ask you to please plan ahead, allow for extra travel time and drive safety. Your patience is appreciated.

All closures are weather dependent. Should inclement weather occur, this closure will take place the weekend of July 25-28.

Wisconsin Avenue Commuting

Alternative Routes

While Wisconsin Avenue is the most direct route to campus, trying a different route may save you time. Watertown Plank Road remains open during construction from Discovery Parkway to the east. The following options are worth a try.

  • Swan Boulevard: Swan Boulevard is open and delay-free. Swan serves as a vital link to our campus. Access to Swan Boulevard is available from Watertown Plank Road just east of Highway 100 and from North Avenue.
  • Discovery Parkway: Discovery Parkway is open and connects Watertown Plank Road (just west of 92nd Street) to Swan Boulevard. From Swan Boulevard, Discovery Parkway flow freely onto Watertown Plank Road eastbound with no traffic signals or stop signs. Likewise, westbound Watertown Plank Road traffic will flow freely onto northbound Discovery Parkway without traffic signals or stop signs.
  • Highway 100: Highway 100 is fully open between North Avenue and Bluemound Road, including additional through lanes and multiple intersection turn lanes. As an alternative to taking Wisconsin Avenue to campus, take Highway 100 to Watertown Plank Road east - it doesn’t close until just east of Discovery Parkway/Innovation Drive. Turn north onto Swan Boulevard to south Discovery Parkway which flows onto east Watertown Plank Road.

Wisconsin Avenue Parking Restrictions

New parking restrictions are in effect on Wisconsin Avenue between 92nd Street and 87th Street to assist with traffic flow. Parking will no longer be allowed between 6-8:30 a.m. and 3:30-6 p.m., Monday-Friday.
