Footbridge over the River Nervión in EtxebarriEtxebarri, Spain
This footbridge connects two neighbourhoods that are divided by the Nervión River in the town of Etxebarri, next to Bilbao. The bridge gives easy access to a new underground station, and becomes a landmark of a newly-developed part of the town. The structural scheme of the footbridge, which is made of steel, is a single-plane, slightly-tilted, steel-bowstring arch. The triangular-shaped arch itself separates cyclist and pedestrian traffics, the transit platforms cantilevering from a trapezoid-shaped main girder (the tie in the bowstring layout) by means of ribs. The cyclist pavement is a concrete slab, while the pedestrians walk on an Iroko timber decking.
