Well this was the scene this morning. All of the Close Sidewalk barricades have been destroyed and or pushed aside.
If there was some sort of public safety with the subway block building, they would have yellow taped the area off and have someone making sure the barricades are always properly in placed. The whole 3-4 days weekend since the barricades have been in placed, they have been ignored by everyone, including the public, the homeless guy, the city officials, the property owner.
The only other reason I can think of, the sidewalk bricks are the problem.
