DESCRIPCION
Two viaduct were designed in Luko and Bentabarri, with other four bridges in the motorway between Vitoria and Eibar.
For maintaining the concordance, all the structures were designed with the same typology, with a prestressed concrete deck with a hollowed slab of constant depth and large lateral cantilevers. Over the piles, there are also parabolic increments of the depth in the surrounding area of the pile, being the major depth, over the pile, providing the bridge a great safeness and response appearance.
The Luko viaduct, with its 84 meters, distributed in two 42 m spans, is formed by two 15.8m-width decks and the central pier has a characteristic V-shape.
The Betabarrri viaduct, 85 length, has a span distribution of 23+39+23m.
