Helix-shaped footbridge unites Madrid over historical river

摘要

The Pasarela del Arganzuela, a footbridge designed by Dominique Perrault, spans 250 meters across Madrid's Rio Manzanares, uniting both sides of the expansive city. More than 4,500 sm of stainless-steel Escale mesh from GKD-Gebr. Kufferath AG-gives the bridge a helix shape. In Spain's capital city, highways have been pushed underground, transforming the river-banks into parks and promenades. The spiral-ing design of the bridge allows natural light to seep through the permeable structure, while at night it is transformed into a golden ribbon floating above the river.
