The bicycle/pedestrian path markings are standard for Central Europe. The landscape features a canal or river with a bridge, typical of the flat, temperate regions of Germany or the Netherlands. The overcast, grey sky and bare trees suggest late autumn or winter in a northern climate. I suspect this is near a canal in Germany. I am somewhat sure.

The graffiti style and the concrete structure of the underpass are very common in urban Germany. The blue circular sign visible in the distance is a standard German traffic sign for a mandatory path for pedestrians and cyclists. The overall infrastructure and vegetation point toward a suburban area in a German city. I am fairly confident this is in Germany.
