It looks more to me like that is a bridge used to support a big pump for
some kind of irrigation. Note the pump in the middle with the overhead to
rise the pump.

I suspect that the "bridge" served to hold a "hydralic ram" which uses the
velocity of the water to pump a small portion of the water to the level of
the surrounding fields.
OR, it could just be a structure to hold a water turbine is the center of
the stream.
The structure in the middle tooks like something used to pull something
normall in the stream bed to the level of the bridge floor for maintenance.

Nope. Hydraulic rams need a head of water above the pump so that the water
drops into the ram. - its the action of the water falling into the ram that
makes the pumping happen.

Nope, yourself.
You just don't understand how a hydralic ram operates.
It uses the kinetic energy of a stream to raise a small portion of water
well above the level of the stream.

John, you are wasting your time.
