New power lines in the Zoo Interchange

MILWAUKEE COUNTY (WITI) — American Transmission Co. (ATC) announced it has completed its work in the Zoo Interchange to relocate and erect new electric transmission infrastructure as part of the interchange expansion plans.

ATC began the transmission line portion of the project in June 2013 to relocate seven overhead 138-kilovolt transmission lines and erect 59 single pole structures to replace 58 lattice towers. Just over 11 miles of new wire were strung from south of Greenfield Avenue along the east side of US 45/I-894 in West Allis, north to the Zoo Interchange and then west along I-94 to ATC’s Bluemound Substation.

ATC’s restoration work may continue through spring 2015 – removing the former lattice towers and construction mats, and completing final grading of the area.

The cost of ATC’s Zoo Interchange project work totaled $50 million.
