It is curious to see how the canal passes over the river by a bridge, like the old aqueducts.

Here the canal crosses the Hers, the path is a bit stony. More information: https://de.wikipedia.org/wiki/Canal_lat%C3%A9ral_%C3%A0_la_Garonne?wprov=sfla1

Built in 1840, the Hers Canal Bridge spans the Hers, also called Hers-Mort. This 89 km river flows into the Garonne about 2 km from the canal bridge.
