Good warning and awareness, Jerry.
Right beside the warning, "Do not walk beneath ladders", there should be a placard with this, "Do not go beneath, on top of, or anywhere near the sides of bridges.....always find a detour without bridges."
A couple of years ago a bridge collapsed in Pittsburgh, there was a walkway below it. Fortunately no one was under the bridge when it collapsed, but it took a couple of days before they were sure.
