The history of a mythical road

In the 18th century, roads were built through the Alps to communicate with the various fortifications. But they also served many remote communities. And the construction work was a source of income for local people.

At the end of the 19th century, the Touring Club de France, whose original remit was to promote tourism by bicycle, opened its doors to motorists. It campaigned for improvements to roads and signposting, and for the provision of facilities in wayside inns. It laid out numerous tourist itineraries, with viewpoint indicators, including, in 1911, the Route of the Alps, which was soon being used by PLM's charabancs and coaches, though it was completed only in 1937, when President Albert Lebrun cut the ribbon on the road across the Iseran pass.

Automobile tourism was initially reserved for a privileged few. But in the '30s, as demand rose, the car makers began producing smaller vehicles at lower prices. And tourism took off after WW2, with the appearance of the first truly mass-produced vehicles: the 2CV, the 4CV, the Dauphine, the Beetle, etc.
