WisDOT Milwaukee Zoo Interchange Reconstruction

The Zoo Freeway is a major north-south facility in western Milwaukee County,
running 13.5 miles from the Hale Interchange in Greenfield to the North Interchange
in northwest Milwaukee. At the Hale Interchange, the I 894/US 45/Zoo Freeway
meets the I 43/Rock Freeway and the I 894/I 43/Airport Freeway, while at the North
Interchange, the US 41/US 45/Zoo Freeway intersects the STH 145/Fond du Lac
Freeway. The project includes six service interchanges: North Avenue, Watertown
Plank Road, Bluemound Road, 84th Street, WIS 100, and Greenfield Avenue. The
major roadways include: WIS 100, Watertown Plank Road, and Glenview Avenue.
The Zoo Interchange reconstruction project provides efficient movement for existing
and future traffic at the Watertown Plank Road interchange and improves safety
and efficiency on adjacent roadways including Highway 100, Bluemound Road,
Watertown Plank Road, and Glenview Avenue/84th Street.
