It's going to be turned the other way.
But we'll find out the real answer soon enough. Once it has a deck, I'm going to fill barrels of water out on the middle of the bridge. I'll have a transit set up to measure how much it dips.
I think he was looking for an aesthetic difference and a shallow arch would look nicer than my flat thing. I don't much care, just want to drive across. Someone had suggested plopping a shipping container across the gap and cutting out an end. Instant covered bridge! I liked the idea but my wife immediately vetoed it.Anyway, you would need a significant arch to make a difference in your case.
