Re this sidewalk sign.
Years ago, one small but extremely busy bridge that went from downtown into South Austin was closed to pedestrians because it was getting more and more dangerous to walk. In fact, someone was killed when an SUV jumped the curb.
They built this gorgeous modern pedestrian bridge mere meters from it.
On the old bridge and barrier and sign as above was put on all 4 access points on the now vehicle only bridge.
I had to drive over that bridge at rush hour every day, and would constantly see people squeezing by the barrier.
Even years before, when I would cross that bridge when cutting from one side of the park to another, I would be terrified walking across.
