The Isthmus Viaduct is part of the Madrid-Valencia High-Speed Rail Line and is located within the Contreras Reservoir–Villargordo del Cabriel section. The construction of this viaduct presented significant technical challenges, as its location features conditions that make its construction particularly difficult.
The total length of this impressive structure is about 830 meters, divided into 12 openings. The maximum length of these spans is about 66 meters.
The height of the piles, made of reinforced concrete with a hollow rectangular cross-section, is between 21 and 71 meters, which are constructed on site using self-climbing formwork. The The maximum height of the viaduct is about 80 m, approximately.
For the construction of the dashboard, consisting of a a beam with a cross-section 14 meters wide and 4.4 meters thick, a self-supporting scaffold (who began working from the step on the side closest to Valencia).
The section where the Isthmus Viaduct is located (the Contreras-Villargordo del Cabriel Reservoir section) is 6.53 kilometers long. The Isthmus Viaduct is the longest structure in this section.
Throughout the construction of the entire section, methods were followed to ensure the maximum protection for the area.
