Arganzuela Footbridge

Dominique Perrault's metallic double-helix pedestrian bridge over the Madrid Río — two spiraling steel ribbons wrapped in a perforated skin, crossing the river where a motorway once ran. Part of the ambitious project that buried the ring road and reclaimed the riverbank as parkland, it's as much sculpture as infrastructure, especially when golden-hour light filters through the metal mesh. For visitors exploring the Madrid Río park, it's a striking modern landmark and a photographer's favorite — a functional crossing that doubles as one of the most distinctive pieces of contemporary design along the river.
