The road markings and the style of the pedestrian bridge suggest a Mediterranean climate, likely Greece. The signage is in Greek script, confirming this location. The architecture and the dry, sunny environment point towards an urban area near Athens. I am fairly confident this is in the Attica region.

The signs clearly display "ΣΚΛΑΒΕΝΙΤΗΣ" (Sklavenitis), a major Greek supermarket chain. The pedestrian bridge and the highway layout are characteristic of the major arterial roads in the Athens metropolitan area. The graffiti and the specific bridge design confirm a suburban setting in Attica. I am very confident this is near a major highway in Athens.
