The path markings and the red-and-white bollard are characteristic of Australian cycling infrastructure. The heavy-duty fencing and the industrial yellow bridge structure suggest a rail corridor in a suburban area. The vegetation and the bright, clear sky are consistent with a temperate or Mediterranean climate typical of Western Australia. I suspect this is near a train line in Perth. I am moderately sure.

The yellow bridge structure and the specific design of the pedestrian/cycle overpass are very distinctive of Perth's rail infrastructure. The signage visible in the distance, though blurry, fits the style used by the Public Transport Authority of Western Australia. The surrounding landscape and urban development are consistent with the suburbs along the Fremantle or Midland lines. I am quite confident this is in Perth, Australia.
