Online-Puzzle «Bridge»

Looks like the same bridge but on the other hand. An old stone bridge and a cattle fence on a river in Kent, England.
There is no pedestrian part of the bridge, it turns out that it serves only as a hedge from cattle so that the cattle that come to the watering hole does not wander anywhere and would not frighten the ducks.
Perhaps there is a water conduit inside and the bridge is an aqueduct in addition
