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
T


You are absolutely right. It is all about displacement. And as said
earlier the theory is very basic and discussed in High School physics.

An earlier claim (by bassy) that the load is static is also wrong due to
varying degrees of pedestrian traffic on either side of the bridge and
possible wakes caused by boats traveling at higher speeds.

I though bassy was structural design engineer. ;-)
