Abstract:
The viaduct over the River Deba on the Basque-Y high-speed rail line crosses the river valley in an area near Bergara, a town in the Spanish province of Guipuzcoa. The deck is a prestressed concrete box girder with variable depth over the piers. Built with an underslung movable scaffolding system (MSS), its span arrangement is 50+80+70+60+3×65+70+65+70+3×65+45m.On the back of developments in recent years in Spain, the technology could be deployed to build the main 80m span, setting a national record for high-speed rail span length using this building system.The article contains a detailed description of the characteristics of the viaduct, as well as its construction and the monitoring systems applied during its erection.
