A water bridge for boats built over a river. Pretty amazing!

Google NYS Erie Canal (1 version) for examples nearer to home.




Can you imagine the weight of bridge structure, water & boats.
I wouldn't want to spend too much time under it.

boat adds absolutely no weight to this bridge... physics 101

Prove it...!!


Think about what causes a boat to float (or anything to float). His point
will come to you. Or Google displacement

That's not proof. First of all, you need to ensure, and prove that the
displaced water is moved OFF OF THE BRIDGE. If there are gates at
either end, then it isn't.
