Valsordo Bridge over the Alberche River in El Tiemblo, Ávila (Spain)

Next to the Valsordo Bridge there was a granite made bull of a considerable size with Latin inscriptions on its sides, as cairn or limit of two provinces: Tarraconensis and Lusitania. On one side was written: "Hic est Tarraco, non Lusitania " and on the other: " Hic est Lusitania, non Tarraco" to indicate that the respective side in each inscription was the territory of each of the provinces. There was a belief that the famous Bulls of Guisando were five, and one of them was moved to the Valsordo Bridge, the one referenced in the legend.

Legend from El Tiemblo

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
