The A43 autoroute (French: Autoroute A43), also known simply as the A43, the Autoroute alpine (lit. 'Alpine motorway') or the Autoroute de la Maurienne (lit. 'Motorway of Maurienne', after Aiton), is an autoroute (motorway) in France. Travelling through the French Alps, it connects the city of Lyon with the Tunnel du Fréjus, near Modane, which passes the Italian border towards Turin. The autoroute opened in phases as it was constructed between 1973 and 1998.
