"One of the most important and striking legendary bridges in Cantabria. It represented a major advance in communications. Previously, the crossing had to be done by boat, of course, a long time ago.
Its structure will give you the impression of a major construction. Come and discover it."

"Excellent scenery. Nice to see the Colindres fishing port, Treto Bridge, Colindres Viaduct, and the Asón Estuary."
