Introduction
The A67 motorway linking Santander to Mérida traverses over 500 km of Spain's most diverse landscapes, from the Cantabrian coast to the plains of Extremadura. Completed in 2004, this route cuts through the Cantabrian Mountains via the 2.3 km-long Puertos de Reinosa tunnel, a feat of engineering that shaved off two hours from the old mountain roads.
