[UPDATE BELOW] West 57th Street between 6th and 7th Avenues is closed because the crane at 157 West 57th Street—yes, at the massive 157 West 57th luxury condo skyscraper under construction—got stuck at the about 20th floor. With 13,000 pounds of concrete.

You'll recall that this is the very same location where a crane partly snapped during Hurricane Sandy and dangled over West 57th Street.
Oh good that crane on 57th is broken again. I was starting to miss their life-threatening shenanigans!

WABC points out, "The malfunction is causing additional concern because New York City is under a tornado watch."
Update 4:41 p.m.: The load was slowly lowered down to the street over the course of six hours, finally returning to terra firma at about 3:30 p.m., and NBC New York reports that the street has reopened.
