Zoo Interchange Project
PROJECT STATUS: Completed and in service
American Transmission Co. is relocating seven overhead 138-kilovolt transmission lines to accommodate the Wisconsin Department of Transportation’s expansion of the Zoo Interchange (Interstate Highway 894-94/U.S. Highway 45). All of the circuits will be moved to accommodate expansion and realignment of the interchange and the existing lattice structures will be replaced with single poles.
The project also involves substation work, including modifications to the Brookdale and Bluemound substations and construction of a new substation on the grounds of the existing We Energies 96th Street Substation.
