Donald Grieb, famous for his design of “The Domes” of Mitchell Park Horticultural Conservatory (
MI91
), used the repeated arch motifs typical of New Formalism for this depot. Although his domes became one of Milwaukee’s landmarks, local residents criticized the Amtrak station for its skinny windows, asymmetrical open-arched bell tower, and unusable entrance portico. In 2000, the Wisconsin Department of Transportation purchased the building for an intermodal transportation center for rail, cabs, and buses. Its top two floors provide offices for Wisconsin DOT planners. The depot annually serves more than 400,000 passengers.
