The bridge, located in front of the sports arena, has improved the pedestrian flow between the two banks of the river. The municipality wanted to avoid the use of automobile traffic in the area, improving the mobility of bicycles and pedestrians in the urban district. In this bridge’s location, a town with a rich cultural memory and natural surroundings, a sensationalist, exhibitionist or superfluous structure would not fit. The idea is to design a bridge that enhances the natural value of the river and understands its environment, instead of creating a useless or pointless landmark. Pedelta’s proposal is a pure and sober structure, but with an innovating and challenging spirit. It is the first bridge structurally combining two high performance and corrosion-resistant materials: the stainless steel and the glass fiber reinforced polymers (GFRP).
The bridge crosses a 28 m long channel and has a 5 m wide deck. The structural outline is clear and conceptually very simple: two Vierendeel trusses which function as a guardrail and where the lateral lighting and handrail is integrated. Pure simplicity.
Pedelta received the Civil engineering mention award (2nd Prize) in Construmat Exhibition for the Zumaia hybrid (Stainless steel and GFRP) footbridge (2009).
The proposal is a pure and sober structure, but with an innovating and challenging spirit. As the pedestrian bridge is located in a corrosive environment due to its proximity to the sea (less than 400 m), the selection of materials with high corrosion resistance has been crucial.
