900 Randolph has been fun to watch. Nothing fancy, nothing out of the ordinary. But tall, sleek, and darn near topped out. The skip is numbered up to 34; there are at least six poured floors above the 34th floor. That puts it into the 40s. It’s a 43-story building I was told there would be no math, but even I know that only leaves a couple levels to go.

Enjoying the photos? Metra and CTA rides (and Amtrak trains to Milwaukee), Zipcars, Divvy Bikes, camera lenses, domain fees, snacks & energy drinks, and comfortable walking shoes add up. You can help offset expenses by making a greatly-appreciated donation to Building Up Chicago.
