Fréjus Road Tunnel

The Fréjus Rail Tunnel (also called Mont Cenis Tunnel) is a rail tunnel of 13.7 km (8.5 mi) length in the European Alps, carrying the Turin–Modane railway through Mont Cenis to an end-on connection with the Culoz–Modane railway and linking Bardonecchia in Italy to Modane in France. Its mean altitude is 1,123 metres (3,684 ft) and it passes beneath the Pointe du Fréjus (2,932 metres (9,619 ft)) and the Col du Fréjus (2,542 metres (8,340 ft)). Headed by the Savoyard civil engineer Germain Sommeiller, construction of the tunnel commenced during August 1857, at a time when both ends of the future tunnel were in the Kingdom of Sardinia. From the onset, the tunnel was an ambitious engineering challenge, its gallery being twice the length of any tunnel previously constructed. Some figures believed that it would take as many as 40 years to complete; the total construction time was 13 years, the work having been greatly accelerated by the introduction of new technologies such as pneumatic drilling machines and dynamite. On 17 September 1871, the Fréjus Tunnel was opened to traffic for the first time, facilitating a new era of interaction between France and Italy. The Fréjus tunnel remains an important link in the connection between Rome and Paris, via Turin and Chambéry. Following the development of car and truck transportation, the Fréjus Road Tunnel was built along the same path from 1974 to 1980. During the 2000s, the Fréjus Rail Tunnel underwent a series of works to modernise and improve it, including the increase of its bore to accommodate wider rail vehicles, such as container trucks on piggy-back wagons, as part of the Autoroute Ferroviaire Alpine. A future high-speed rail tunnel to improve transit capacity between France and Italy, called the Mont d'Ambin Base Tunnel, is being planned as part of the Turin–Lyon high-speed railway project.

Col du Fréjus (el. 2,542 metres) is a mountain col path in the Cottian Alps on the border between France and Italy. It connects Bardonecchia, Italy to Modane, France. The path over the mountain pass is unpaved and limited to walking traffic. Vehicular traffic utilizes either the toll Fréjus Road Tunnel or the nearby Col du Mont Cenis.

Punta Bagnà (in Italian) or Cime du Grand Vallon (in French) is a mountain of Savoie, France and of the Province of Turin, Italy. It lies in the Cottian Alps range. It has an elevation of 3,129 metres above sea level.

The Punta Nera is a mountain of Savoie (France) and of the Province of Turin (Italy). It lies in the Cottian Alps range. It has an elevation of 3,047 metres above sea level.

Le Grand Argentier is a mountain of Savoie (France). It lies in the Cottian Alps range (or in the Massif des Cerces, according to French alpinistic literature) at an elevation of 3,042 metres (9,980 ft) above sea level.

Pointe de Paumont (in French) or Cima del Vallone (in Italian) is a mountain of Savoie, France and of the Province of Turin, Italy. It lies in the Cottian Alps range. It has an elevation of 3,171 metres above sea level.

The Colle della Rho (in Italian) or Col de la Roue (in French) is a mountain col at 2,541 metres (8,337 ft), at the border between the massif des Cerces and the Cottian Alps.

The Col de Pelouse (Italian: Colle della Pelouse) is a mountain pass in the Alps on the border between France and Italy. It lies at an elevation of 2,793 metres (9,163 ft) and has a north–south orientation. On the northern (French) side, the pass leads into the valley of the Maurienne; on the southern (Italian) side, the Val di Susa. To its west rises the summit of Gardoria and to its east that of Aiguille de Scolette. It connects Avrieux in France with Bardonecchia in Italy. A small barracks, Bivacco LXIII, lies in ruins on the Italian side. It was built in 1939 to house twenty soldiers. In 1940, during the Italian invasion of France, Italian troops passed through the Col de Pelouse. There was fighting just north of the pass on the French side. For mountaineers, the Col de Pelouse is the easiest start point for climbing the Aiguille de Scolette or the Pointe de Paumont to the west.

Bardonecchia railway station (Italian: Stazione di Bardonecchia) serves the town and comune of Bardonecchia, in the Piedmont region of northwestern Italy. The station is a through station of the Turin-Modane railway. The train services are operated by Trenitalia and SNCF. Since 2012 it has served line SFM3, part of the Turin metropolitan railway service.

Trampolino al campo Smith was a K40 ski jumping hill located in Bardonecchia, Italy.

Rocca Bernauda (French: Roche Bernaude) is a mountain of the Alps of 3,222 metres (10,571 ft). It has been the westernmost point of Italy since the cession of Valle Stretta (Vallée Étroite) at the Paris Peace Treaties of 1947.

The Grande Traversée des Alpes (GTA) is a long-distance hiking trail in the French Alps, connecting Thonon-les-Bains on Lake Geneva with Nice. It constitutes the southernmost part of the Sentier de Grande Randonnée GR5.The GTA was created in the beginning of the 1970s. It was soon imitated in Italy, where another GTA, the Grande Traversata delle Alpi was created. The Via Alpina uses some legs of both the French and the Italian GTA. The Grande Traversée des Alpes (GTA) is also the name of the association which manages the GTA trail as well as the French part of the Via Alpina and other projects in sustainable, interregional mountain tourism in the French Alps, located in Grenoble.
