A strong indicator of future tower cranes is a present caisson rig. Stalworth Underground has a couple of them on site at Lake and Green Streets for the Hoxton Chicago hotel. Get off the CTA Green Line train at the Morgan for a great view of an American Flag, a water tank, and a caisson rig. A caisson rig with the Stars & Stripes attached, that is. It’ll be a tower crane soon enough.
The Chicago Water Tank and American Flag sit atop East Bank Storage, 730 West Lake Street.
