The image depicts an unoccupied railway bridge, now a pedestrian walkway, over the Douro River in Peso da Régua, Portugal. The perspective is centered on the bridge, looking along its length. The bridge features a dark wooden plank deck, extending into the distance. Grey metal truss arches form the structural elements along both sides of the walkway, diminishing in size towards the horizon. Matching grey metal railings border the wooden deck. The sky above is overcast with scattered grey clouds. In the background, rolling green hills, likely terraced vineyards, rise. Several white-colored transmission towers or pylons are visible atop these hills. A portion of another bridge or viaduct is discernible to the far left in the background. No individuals or vehicles are present on the bridge.
