Unless you lived at the Randolph Place Lofts (165 North Canal Street), you probably didn’t have a need to use the strange, hanging alley that arced across the vacant space in the 100 block between Lake and Randolph Streets. Aside from moving trucks engorging themselves, and trainspotters leering at the silver streaks below, it was a quiet place.
But all that’s changed now that 150 North Riverside is under construction, and nearing completion. West Loop Spy Justin dunked our tip line with a photo showing the alley between the loft building and the new skyscraper being transformed into an urban oasis. The street-level void has been decked over, safely hiding the Amtrak and Metra trains trundling below. While on top trees, paths, and miniature parking garage come together.
And if you’re looking for a piece of trivia for your next Cubs watch party, you should know that at 752 feet, 3½ inches, this is the tallest building in Chicago west of the river.
