I've just read a post from Ender describing how the Camino del Salvador folks have just finished waymarking a new exit from Pola de Lena. He says it no longer goes on the National highway, but rather goes to Villallana on a service road and along the river. Additional advantages are that it goes by Villallana's church of Santiago and also an old and renovated pilgrims' hospital. Ender will change the guidebook soon and I'm sure we'll get updates. Good to have someone always trying to get us peregrinos off the main roads!
