Good news for future pilgrims on the Via de la Plata. It seems that provincial authorities are working on a new route after Castilblanco de los Arroyos, avoiding the long road walking. From the Spanish link I understand that there are 157.000 euros from agricultural funds available for this. They give no date on the opening of the new route.
