Could a suspension bridge be built with floating caissons in place of the central towers?

Like say, if the water in the mid-span was too deep to make building support towers from the floor of the body of water economically feasible.

Answer:
I think there is a floating bridge like that in Seattle harbor where the water is about 600 feet deep.

I would say, without knowing the details about the body of water involved, that the answer is 'no'. However, why does it have to be a suspension bridge? A conventional floating bridge might be feasible, with suspension 'connectors' where it reached land.

If the towers were built with floating caissons, the towers would sway too much, fore and aft, side to side, up and down.

It'd make "galloping gerty" in the Tacoma Narrows look like a ride on a dime-store pony.

No. The whole idea behind suspension
bridges is that you can build bridges
5 miles long, rather than 100 feet long.
