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

Nah, I'd stay under it all day. It's not really that bad. For one
thing, the water (the heaviest element) is a totally uniform load,
meaning it's spread out over the entire surface, not a point load,
plus, it's static not dynamic. Now, there is some tremendous loading
going on, but it's all very easily accounted for, nothing abnormal
going on.

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

Theoretically, the weight of the water and boats is a constant. What varies
is the people walking across or standing on the bridge.

Here is the URL with a drawing of the Aqueduct over the Genesee River (Still
in use as the Broad Street Bridge. The Upper deck is the "street" and the
lower deck is the (now idle) original aqueduct.

Another aqueduct, in Palmyra, (hometown) lots of summer fishing here as a
kid. Apparently, hydraulic engineering back in the early 1800's, wasn't up
to task of controlling natural streams and the canal, hence the numerous
devices to keep the waters separate.
