This is a bridge over a shallow river.
Or it appears that way.
In fact it is a bridge over an extinct river. Part of the River Turia in Valencia, which runs through the centre of the city, but after major flooding was diverted around the outside of the city, and the old riverbed has been converted into a park that goes almost all the way to the Mediterranean and allows pedestrians and cyclists to get around a lot of the city without the need for roads.
