This spectacular viaduct, which is named in honour of the engineer Martín Gil who designed the project, was built in the 1930s and 1940s and is known for being the largest concrete arch viaduct in the world at the time of its construction.
A key aspect of the project is the use of the BRIO multidirectional scaffolding, specially adapted to the bridge’s complex geometry to provide access to all working areas: the arch, piers, deck, and sides of the viaduct.
