Extradosed Bridge over the river Deba (Vitoria - Gasteiz - Eibar Motorway

El presente articulo describe las principales caracteristicas y sistema constructivo del Puente sobre el rio Deba, perteneciente a la Autopista VitoriaEibar en el Enlace de Malzaga. El puente, que discurre en curva, tiene una sucesion de luces de 42.00 + 66.00 + 42.00 m, cruza un ferrocarril, el rio Deba y una carretera. Para resolver el problema de galibo estricto sobre la carretera se ha disenado un tablero de hormigon con una seccion en forma de "U", cuyo canto sobrepasa la plataforma de rodadura y en el que el pretensado sobresale del canto de la seccion. El tablero esta soportado por unas pilas con disposicion en "Y". La solucion, cuyas especiales caracteristicas estan obligadas por la circunstancia de galibo, aporta el atractivo formal derivado de su singularidad. (A). English abstract: This article describes the main features and construction system relating to the Bridge over the river Deba, belonging to the Vitoria- Eibar Motorway at Malzaga lunction. Running in a curve, the bridge has a succession of spans measuring 42.00 +66.00 + 42.00 m, crosses a railway line, the river Deba and a road. A "U" shaped cross-sectioned concrete deck was designed for overcoming the strict clearance problem over the road. Its edge protrudes from the roadway and the prestressing protrudes from the cross section's edge. The deck is supported by "Y" shaped piers. The solution, whose special features are compelled by the clearance requirement, provides the attractive shape deriving from its uniqueness. (A).
