If you look at the picture while it's standing, the design has the diagonal braces all running the same way. Any homeowner who has knocked together a wooden gate could recognize that as abnormal. If the bridge were standing, I might think "huh, I guess the did the math and it works fine like this". But since it's scattered across the riverbed, I guess they didn't.
