“Why is there not a big round Bollard on top of that Fencing?”
My guess is that is one of the special adaptations made for the local environment - specifically to minimize impeding water flow and wind load in the event of severe flooding and winds during hurricanes.
They have also galvanized their bollards for the moist environment, and expanded the gap between bollards to five inches (rather than the standard 4) to allow greater potential water flow during floods, and also to accommodate the skull size of the endangered local ocelots, and provide them access to the river.
A few years back a hurricane flooded the Rio Grand. Water was DEEP for a mile or more on the Texas side. I spent a lot of time afterward doing asbestos, lead, and mold surveys/assessments. The flooding continued for a while. I still get calls on damage from that hurricane. It traveled straight up the river. If the wall didn’t allow for that flooding it would wash out and make the flooding worse.
There are two lakes upstream, and they sometimes have to release a lot of water too.
