Road construction Urdon-Treviso dates back to the mid-nineteenth century, once the existence of zinc in the Eastern Massif of the Picos de Europa was known. In this period mining companies began to open access roads needed to transport the extracted ore at the mines in Andara to the bed of the River Deva, in the gorge of La Hermida, where it was loaded on flat-bottomed barges for transportation to Unquera. Once in Unquera, the ore was loaded on ships to be sent to Belgium, Germany and the UK, although sometimes it was transported by rail for shipment in Santander.

The transport of ore from Andara to La Hermida was done by way of Bejes as well as Treviso-Urdon. It is a result of the realization of the latter when some signs of sulfides and carbonates of zinc in the Invernales of Prias, of which still remain to witness some mine entrances temporarily exploded.

The biggest drawback in the exploration of these mines was transporting ore since Augustin Mazarrasa, director of the mines of the same name and who ordered the building of the road Teviso to Urdon, forbid the use of this society which operated mines Treviso. To overcome this obstacle a cable driven by a kind of ox-driven waterwheel was installed, down and up the ore mining provisions and utensils. The mechanism of the wheel which was still vestiges located in Cotero The cross (the important corner last accessed according to the Invernales of Prias, immediately above the Balcon de Pilatos). With an intermediate pole loading and unloading in Ciabedo (somewhere after Bargona), cable ended at one kilometer and a half Urdon.
