Bridges have a way of attracting an element of society that is unfortunately something we must deal with — the homeless. This post is not to propose making their lives harder but rather to share a solution for controlling public space under bridges.
I came across a solution that seems to be almost perfect as it is cheap, no one will steal it, you cannot sleep on it and it should age and discolor evenly and look like other aging concrete structures that are not considered unsightly.
If you have read this far I am pleased as the idea is so simple that the photos clearly show the solution to the problem. I was surprised when I saw this installation that it was not being used in other locations. The large concrete rubble from recycled concrete creates a clear, uniform surface no one could use. The concrete pieces are large and similar in size. There are no small pieces that would allow weeds to grow. Simple, very effective and supports sustainability.
The one issue is that trash will blow into it and sooner or later will fill the crevices and then be visible. I expect that when that occurs a good backpack style blower will blow the visible paper and vegetative debris to the other side to be retrieved.
If you want to see it “live” then go to the north side of the Montrose Bridge over Buffalo Bayou in Houston Texas. The walkway in the foreground of the first image is the new Rosemont Trail that connects Montrose’s pedestrians to the hike-bike trail along Buffalo Bayou and the new Rosemont pedestrian bridge over Memorial Dr. and the Bayou.
