CX with Bridges?

So I am on a construction kick, dreaming up ideas for my own track and thinking of other possibilities, and I know a few CX courses that we race on in the OVCX have wooden bridges on them. Anyone know of any courses anywhere else that have ever used a more elaborate bridge system, or funky terrain setups that just worked out. Possibly even courses that are more city like with concrete structures in them. Ouch comes to mind with thinking of eating a concrete step, but cobbletones can't be much easier to land on. I saw a video from a CX race in Southeast Michigan where they ran across the beach.
