The region is also crossed by two major ancient routes:

The Way of St. James, mentioned as a World Heritage Site, now a hiking trail and a motorway, from east to west.

The Roman Via de la Plata (“Silver Way”), mentioned above in the context of mining, now a main road through the west of the region.

The road network is regulated by the Ley de carreteras 10/2008 de Castilla y León (Highway Law 10/2008 of Castile and León). This law allows for the possibility of roads financed by the private sector through concessions, as well as the public construction of roads that has long prevailed.
