Ulma Construction
Reusing the maximum amount of material possible and reducing on-site deadlines
The Zumelegui viaduct is part of the high speed railway platform that will connect the three main cities of the Basque Country. Known as the "Basque Y" due to its geometry, it will have three lines and a central junction located at the same point.
The 481 m long, structure consists of 7 spans whose distribution has allowed the simultaneous construction of a road, without interfering with traffic.
When designing the project, priority was given to reusing the maximum amount of material possible and reducing on-site deadlines, so after each pouring, the shoring and formwork were moved to the next pouring while the deck was shored with a single tower.
