The Pasarela del Arganzuela pedestrian bridge is now in place, bringing a major construction project in Madrid to a conclusion. The bridge covers the Rio Manzanares and the broad river banks, is the brainchild of French architect Dominique Perrault. A stainless steel weave wraps round the steel structure, which tapers like a cone from outside to inside from both sides - turning the bridge into a silver shimmering helix. Within the structure, the softly refracted light creates a pleasant atmosphere. The two sections of the bridge meet in the central platform in the middle. The helix is intended as a metaphor for the growing links between the two districts otherwise separated by the Manzanares river. During the night, the bridge lights up like a golden spiral.
