Does anyone know why in the world that little pedestrian bridge has those things on the side? Guardrails? Why in the world would they be down, and what's the point in allowing them to be either up or down? Weird.

Interesting. It's so easy to forget about the power of water.

If they can’t be secured down that would not be the reason.

It is entirely to minimize the drag force and entanglement option of the bridge, during floods. As we all know floods drag everything downstream, small branches when tangled up act like a sheet or wall giving the water a much larger resistance to flow over/through and increasing the risk of the bridge collapsing.


As a kid I spent days and weeks on end damming up a swift flowing river, studying the water flows for hours on end after each stick was added, I should have become a 'river engineer' I still know more about water flow than I care to know.

My nephew's wife does that. Environmental Engineer is her degree I believe. You want to put a dock in a river? You have to get her blessings first. :)

I was sure that was to avoid low flying drones.

Interesting, never thought of it, but combined with cccc's answer it makes eminent sense....

I don’t see what would keep at least one side from being pulled back up in flood waters?
Just laying them down isn’t going to do it.

Fuck Adobe!

There should be pins that fit through the open holes on top there, after it's laid down.

The construction seems to be about protecting a water or sewer pipe
and the bridge is for access thru the Arcade Creek Nature Preserve.
