2014
On 17 November, the last diaphragm wall of the new Fréjus tunnel was torn down. The commissioning of the second tunnel (which would make the Fréjus Tunnel a two-lane infrastructure with one lane in each direction) is scheduled for 2025.

2000s
On 12 July 2000, S.I.T.A.F. signed a cooperation agreement with ENEA and the Fiat Research Centre, which started a collaboration on projects partly financed by the European Union and involving the development of dialogue between vehicles and tunnels for safer journeys.

This marked the start of a decade of collaboration on various special projects related to tunnel safety and prevention.

The awarding of the 2006 Winter Olympics to Turin then marked the start of a new season of works: the completion (i.e. two lanes in each direction) of the Savoulx-Bardonecchia section, built in the 1980s as a single carriageway with three lanes, and the construction of the SS 589 Laghi di Avigliana bypass.

In the meantime, with the publication of Directive 2004/54/EC of the European Parliament and of the Council on minimum safety requirements for tunnels in the Trans-European Road Network and the consequent issuing of Italian Legislative Decree 264/2006, there was again talk of a tunnel parallel to the Fréjus Tunnel, because only this project allowed the infrastructure to be adapted to legal requirements.

Having carried out studies to support the feasibility of the work and held numerous debates on the size of the tunnel, work would finally start, presumably in 2011.

1990s
The decade that saw the completion of the Torino-Bardonecchia motorway.

1980s
In 1987, the Bardonecchia-Deveys section, about 21 km long, was opened to traffic by Anas, while in 1984 work began on the A32 managed by S.I.T.A.F.: from Deveys to Rivoli; this work continued for about 10 years, thanks mainly to State funding over time.

1980
On 12 July, the Fréjus Tunnel was opened for light-duty vehicles only. On 16 October, the Tunnel was also opened to heavy-duty vehicles.

1974
Preliminary work began in France, as planned by an Italian-French team. On the Italian side, work did not begin until 20 January 1975.

1972
Italian Law no. 878 of 18 December 1972 ratified the International Convention between Italy and France on the Fréjus Tunnel concluded in Paris on 23 February 1972.

In July, the construction of the tunnel was entrusted for the Italian part to COGEFAR and for the French part to VIANINI.

1965
At the inauguration of the Mont Blanc Tunnel in Courmayeur, the two governments of Italy and France signed a memorandum of understanding in which they undertook to build the Fréjus Road Tunnel through the municipalities of Bardonecchia and Modane and to entrust the design, construction and management of the work to two concessionaires: one French, S.F.T.R.F. (Société Française du Tunnel Routier du Fréjus, founded in 1962) and one Italian, S.I.T.A.F.

Thus began the preliminary planning for the construction of the Tunnel and the Motorway.

1960
On 29 October 1960, the Società Italiana per il Traforo Autostradale del Fréjus per Azioni (S.I.T.A.F. S.p.A.) was founded, on the initiative of the city of Turin, the Chamber of Commerce, the Industrial Union, the Province and the Municipality, as well as a number of insurance companies, credit institutions and industrial groups.
