Nueva pasarela en la Reserva de la Biosfera de Urdaibai

As part of the Plan for the Regeneration of the upper part of the firth of Oka, it was decided to build a pedestrian bridge which would give continuation to the footpath between the towns of Gernika-Lumo and Kortezubi. This article describes the various alternatives studied and the design that was finally chosen. The footbridge is a weathering steel box girder, with a main span of 28,40 m. Several aspects of design and dimensioning are also included in this paper.
