La Gaznata Viaduct over the Burguillo Reservoir in El Tiemblo, Ávila (Spain)

“… If the spans of the arches do not exceed 25 metres, as was the case with the Gaznata viaduct, we assemble each of the trusses in a single piece and raise them using rigs fitted to a mast until they are in position. (…) The elimination of falsework almost always results in significant savings in the cost of the bridge.”

José Eugenio Ribera, 

designer of this bridge
