Notices are up along the sidewalk bridge on the northwest corner of Houston at Avenue B from the the NYC Department of Homeless Services (DHS) ...

The flyers state that the DHS along with the NYPD and other city agencies "will complete a clean-up" of this area...and people need to vacate along with their belongings. Anything left behind by tomorrow may be discarded.
As for this longstanding sidewalk bridge, according to the DOB, a permit for it was first approved in December 2014. The city renewed the permit in October. The building, 6 Avenue B, has been vacant for years. The liquor store in the retail space has been closed since the owner died in the fall of 2009.

The area under the sidewalk bridge has been cleaned...

Now everything that was there is neatly stacked a few feet away on the curb (as Neighbor noted in the comments) ...

... and the belonging all have these fake-looking U.S. Federal Use labels...

And "Max," who was sleeping under the sidewalk bridge, is now in the adjacent bus shelter.
