I see your water bridge, but ask, what happens when a big boat wants to get past? I'll tell you what happens- The Barton Swing Aqueduct.

Amazing.

Here's a fun fact action lab pointed out: setting aside wind, etc, the load the bridge has to be designed for is only the water that fills it.
That bridge will have the same force on it from a tanker or a kyaker.

Because boats and ships displace the heavier water?
-
Boat displacement is the amount of water the boat displaces while floating. It is equal to boat weight.
So, if you put a 100 ton boat in enclosed bowl, you will of course get 100 tons more on a scale. However, if you do the same with a large surface body of water (river, lake, ocean), the water will be displaced equally over a large surface area, thus distributing the weight. You still get 100 tons more, but less over the are "under" the boat.

Thankfully that waterway has a bridge so it doesn't have to get wet crossing the river!
