Footbridge over the river Oria

The boundary conditions for the new bridge were the existence of the old stone bridge located 150 m downstream, a small slope in Villabona, a vertical wall in Zizurkil and strict clearance above the river Oria.

The bridge is set into the slope on the right bank, leans simply on the wall on the left bank, and spans the 50.4 m gap in a single stretch. In the midspan, the Corten steel is folded and fixed upwards, to release the vision of the old stone bridge, while trying to express the tough job of a fixed-supported beam.

El alzado del puente sigue la envolvente de la ley de momentos de una viga continua de dos vanos muy descompensados.

Las condiciones de contorno fueron la existencia de un antiguo puente de piedra situado 150 m. aguas abajo, un suave talud en Villabona (empotramiento), un muro vertical en Zizurkil (apoyo simple), y un gálibo hidráulico estricto sobre el río Oria (canto superior). La idea de partida fue realizar un puente sencillo que expresara su trabajo resistente, y no perturbase la visión del puente histórico.
