Scratch One Grant Park off the tower crane waiting list.

Thanks to that tweet from Twitter user @PDNAChicago, we now know One Grant Park has begun installing a tower crane. The crane permit was granted (heh…Granted) way back on February 1, so it’s been a long wait.

The highly-anticipated Rafael Viñoly Architects design for Crescent Heights is delivering 76 stories and 792 apartments, plus 12,000 square feet of retail space, to the South Loop intersection of Roosevelt Road and Michigan Avenue.

Soon, McHugh Construction will have a new tower crane with which to begin sending One Grant Park into the sky. Hopefully, it won’t be a two-month wait like we had for the seedling. (Spoiler alert: It won’t be.)
