Goettsch Partners rendering of Union Station Tower, or BMO Tower. Work has begun next to Union Station in the West Loop.

Cubs. Bulls. Bears. White Sox. Blackhawks. Most folks around Chicago know the names of those local teams. But there’s another team in town making a lasting impression on the city, and in particular, the city’s skyline.

Riverside Investment & Development, Goettsch Partners, and Clark Construction are teaming up again for the third in a trio of eye-popping office buildings along the Chicago River. Union Station Tower will join 150 North Riverside (completed in 2017) and 110 North Wacker (in progress, with completion slated for this year) in making Chicago River Architecture boat cruises much more attractive in the coming years.

They’re doing foundation work as we speak where that ugly parking garage used to be, next to the new CTA bus terminal in the West Loop. The lot, bounded by Clinton Street to the west, Van Buren Street to the south, Canal Street to the east, and the bus terminal to the north, is huge. And it looks even bigger despite the foundation equipment spread to all four corners. Heneghan Wrecking even has rigs on the site, as they finish up demolition work of the previously-mentioned ugly parking deck.

Now, about the tower. It’ll be 50 stories and 700 feet tall. There will be about a million-and-a-half square feet of office space, with a 1.5-acre public park at street level. Also known as BMO Tower, for its anchor tenant, its team celebrated with a groundbreaking ceremony December 20th. Completion and opening is expected in 2022.
