ABSTRACT
four viaducts with different characteristics, conditioned by the place and function are presented in this article.
The Arbizelai viaduct has a length of 424,32 meters, a mixed structure with a box section and cantilevers supported by struts. The main span, 140 meters long, is cable-stayed on the axis.
The Basagoiti Viaduct is 420 meters long and has V-shaped piers, with maximum spans of 125 meters.
The bridge over the Besaya River has a cable-stayed span of 134 meters of span and an access viaduct with four spans with V-piers. It was built by successive cantilevers.
The Etxebarri bridge over the Nervión river in Bilbao has two superimposed levels of metro circulation. The structure is a simply supported beam formed by two superimposed slabs joined by three triangulated knives. It was built by cantilevers with prefabricated segments and provisional supports.
