Finished. The one photo looks odd, because the treads are cut to fit around the posts. Those are straight. I did make a mistake when placing the poles and the tapers are at alternate ends. That caused an angle in the middle. There is a correction by using some tapered wedges. Again, the photo from the end makes it look much more dramatic. In the long run, I know that will bug me, so I will end up cutting some different wedges to fix it, but I was racing the weather.The photo looking up is more realistic.
I will do the next one with the large ends of both poles at the same end. This was a learning bridge for me and I'm overall happy. It is solid. I wouldn't go any longer though with poles. I have a shorter one to build with poles and I will use steel box joists for the longer span.
