Autoroutes of France

The Autoroute A40 is a motorway in France that extends from Mâcon on the west to Saint-Gervais-les-Bains on the east, terminating not far from Chamonix and the Mont Blanc Tunnel. The road runs 208 kilometres (129 mi) through Bresse, the high southern Jura Mountains, northern Prealps and French Alps. It was fully completed in 1990, and includes 12 viaducts and 3 tunnels. The road is maintained by Autoroutes Paris-Rhin-Rhône (APRR and ATMB), comprising part of European routes E25 and E62.[1]


Autoroute A40 is named Autoroute des Titans ("Highway of the Titans") for the dramatic engineering construction through the mountainous sections between Bourg-en-Bresse and Bellegarde-sur-Valserine, and as Autoroute Blanche ("the White Highway") through the snow laden Jura and Alps between Bellegarde-sur-Valserine and Annemasse on the Swiss border.
