It's actually based on steel bridges, but either I'm dumb or there are no small steel pieces like the wooden post. I didn't try recoloring the wooden post to look like steel, but I used wooden columns for the upright pieces and despite having a color picker those don't recolor as far as I can tell.
So for all I know this kind of bridge doesn't even exist in wood.
But its my first build with non-standard pieces. I know some pieces stick out and could be rotated better but I got frustrated dealing with it and figured it looked good enough if you don't stare at it. It's kind of a draft, I suppose.
