Zoo Interchange Local Roads

Environmental, LiDAR, Planning, Survey, Transportation | Wisconsin | Back


In response to public hearing testimony, a new Zoo Interchange freeway reconstruction alternative, developed by Kapur and our Joint Venture partners, reduced project impacts and costs resulting from previous modernization alternatives. This new configuration was known as the Reduced Impacts Alternative and included improvements to adjacent arterial roadway corridors, where many of the 90,000 jobs within 2 miles of the interchange were located.


Four key arterials formed a “box” around the system interchange core: STH 100 to the west, Watertown Plank Road to the north, 84th Street/Glenview Avenue to the east, and Greenfield Avenue to the south. To minimize impacts to the 350,000 vehicles a day using the Zoo Interchange, the design team developed a plan to enhance the adjacent alternate routes forming the “box” in 2013 and 2014, before the major freeway work began.

When system ramp closures were needed in 2015 through 2018, these advanced improvements allowed the adjacent arterial roadways forming the “box” to provide efficient mitigation routes during freeway construction and full access to nearby residents and businesses.

Overall, the adjacent arterial reconstruction portion of the project improved local neighborhood connectivity, access to jobs, and pedestrian/bicycle accommodations.
