SFTRF is a mixed-economy public limited company (SAEM) primarily owned by the French State, established to manage and operate two critical Alpine transport infrastructures: the Fréjus Road Tunnel (12.87 km) and the A43 Maurienne Motorway (67.46 km) connecting France and Italy, under a state concession agreement. The Fréjus Tunnel, inaugurated in 1980, is a vital cross-border link facilitating heavy goods and passenger traffic between the two countries. The A43 motorway serves as the key corridor through the Maurienne valley, providing access to winter tourism resorts and regional economic hubs.
