Today we started our trek along the north coast of Spain. It took a few miles out of Santiago but eventually we were traveling along the north coast on a relatively new motorway (built since the early 2000s) most of the day being spent on the A6. As it turns out much of the terrain along the coast is mountainous (or at least hilly) with valley followed by hill being a continuous pattern. The terrain was clearly a problem to the designers and builders of the new motorways as a new road that dropped down into these valleys and then climbed out again would not be the modern high speed road that was their goal. So the solution was ingenious and we presume expensive. Valleys are crossed by large, high and long bridges and often the hill on the other side is pierced by a tunnel, thereby creating a relatively level roadway out of very up and down terrain. We have not been able to find a reference to how many bridges (viaductos in Spanish) there are on this road but we did see a reference that claimed in one 16 mile section of the road there are 20 bridges and 7 tunnels. This is between Villafranca del Bierzo and Pedrafita do Cebreiro.

By the way it rained off and on all day.

Another Aires tonight. This one beside a gas station. Provides dump, and fresh water. Toilets in the gas station
