Viaduc de Millau

Best route to the South of France. Take the A71 and A75 to cross the Millau Viaduct. An amazing technological construction crossing over the Tarn valley.
Also this is the best motorway to see some great views of the French landscape from the ancient volcanos of the Auvergne to the plains of the Larzac.
It's the route to Montpellier.
Also, technically it was Gilles that took the photo with my iPhone as I was driving. So slight cheat with the photo but it sums up our journey.
