I didn't recall seeing this last winter or the one before. The new street furniture on Bank Street has been suffering the winter conditions. Bike racks have been bumped, those giant advertisement stands are all askew, and worst of all, a lot of the garbage bins are damaged.
It looks like the legs are getting separated from the body of them. I think they've all come out of their holes mounted in the sidewalks.
This one's leg has simply snapped.
Hopefully they're still under warranty (as were the bike racks when they were taken back for repairs after rust started to appear) and maybe the legs can be properly welded to the bins so they won't come apart. Longer bolts on the feet, too, to keep them better planted in place.
