Route Origins and Historical Background
Vision and Conception
The Route des Grandes Alpes was envisioned in the early 20th century by the Touring Club de France (TCF) to connect the isolated valleys of the French Alps. The goal was to foster tourism and economic development by creating a continuous tourist road across the most spectacular Alpine passes (menton-riviera-merveilles.co.uk; mountainpassions.com). The TCF’s ambitious plan required both the construction of new road sections and the modernization of existing, often military, routes.
Construction and Engineering Feats
Work began in 1912, blending new infrastructure with late-19th-century military roads. World War I delayed construction, but the project resumed and culminated in 1937 with the completion of the Col de l’Iseran road—the highest paved mountain pass in Europe at 2,764 meters (alpenpass.com; wikipedia). The entire route was officially paved and named “Route des Grandes Alpes” in 1950 (dangerousroads.org; roadstotravel.net).
Route Evolution
Originally linking Thonon-les-Bains to Nice, the route was later extended to Menton, with new segments added to enhance its Alpine character. Today, the route covers up to 720 km, traversing 17 to 26 mountain passes, including several above 2,000 meters (routeyou.com; alpes4ever.com; tourism.valloire.net). The southern section was notably rerouted in 1995 to traverse more mountainous terrain (roadstotravel.net).
Cultural and Environmental Significance
The Route des Grandes Alpes is a living corridor of Alpine culture, passing through six departments and several distinctive massifs such as the Chablais, Beaufortain, Vanoise, Cerces, Queyras, Ubaye, and Mercantour (roadstotravel.net). Along the journey, travelers encounter a rich tapestry of dialects, local cuisine, and traditions, from Savoyard cheeses to Provençal fare. The route crosses four national or regional parks, including Vanoise and Mercantour, emphasizing environmental stewardship and the preservation of traditional agriculture (mountainpassions.com).
