Those skies on Saturday! You almost don’t notice the tower crane has sunk below the top of 151 North Franklin.

You knew 151 North Franklin had topped out; The John Buck Company told us when they tweeted from the ceremony a month ago. And now comes the next sign that the future CNA Center is getting closer to completion: the tower crane started coming down this past weekend.

Luckily, a tower crane permit was issued yesterday for Eight Eleven Uptown, so things will even out soon. We’ve also got cranes on the way for One Grant Park (planted), 1101 South Wabash, and One South Halsted.
