It is a curved bridge made up of three spans of 81.0 m + 106 m + 71 m, the main span being the one that crosses the Bilbao estuary, in the centre of the city, over the old Euskalduna shipyards.

It has several features that make it unique, the main one being the cross-sectional configuration.

1º) The competition rules proposed two 5.00 m wide pavements and we proposed and obtained permission to join them into a single 10 m wide pavement, which was also covered, as Bilbao is an extraordinarily rainy city.

2º) The main structure is made up of a “Z” shaped beam. The vertical element (somewhat inclined in this case), is a metal lattice, which performs a double role, that of the core of a large “Z” beam and that of visual separation between pedestrian traffic and the road. The lower horizontal part of the “Z” is made up of the deck located under the running rails, which is a box girder 1.95 m high and 10 m wide, which is extended with metal ribs with a 10.5 m overhang towards the pedestrian pavement and 6.5 m towards the traffic side. The upper part of the “Z” beam is formed by the horizontal lattice that forms the pedestrian crossing cover.
