The A43 autoroute, also known as l'autoroute de la Maurienne, is a motorway in France. Travelling through the French Alps, the road connects the city of Lyon with the Tunnel du Fréjus, near Modane, which passes over the Italian border towards Turin. The autoroute opened in phases as it was constructed between the years 1973 and 1998.
