This bridge carries the new road when approaching the Port of Ondarroa, as it passes over Artibay Sound where the sound and port meet. Commissioned by the Municipality of Ajuntement de la Ondarroa, the bridge relives Ondarroa town from heavy harbor traffic and its walkways offers pedestrians new opportunities to enjoy the formerly interrupted waterfront. An asymmetric steel arch separates the box girder carriage deck from the curved, cantilevered pedestrian deck. The constant width steel arch and suspension cables mark the southern edge of the road deck on the landward side, while steel stiffeners project from the seaward side of the curved pedestrian deck, reaching up to the thrust of the arch.
At first glance, this asymmetric arched bridge appears to represent a further investigation by Calatrava into the inclined arch principle. However, closer inspection reveals that the arch and suspension cables in fact conform to a vertical plane. Only the stiffeners are inclined to define the curve of the pedestrian deck. The overall minimum width of the deck area is 20.91 meters (68.6 feet), reaching 23.7 meters (77.7 feet) at its mid-point.
