European route E25 in the context of "Mulhouse"

The Mont Blanc Tunnel (French: Tunnel du Mont-Blanc, Italian: Traforo del Monte Bianco) is a highway tunnel between France and Italy, under Mont Blanc in the Alps. It links Chamonix, Haute-Savoie, France with Courmayeur, Aosta Valley, Italy, via the French Route Nationale 205 and the Italian Traforo T1 (forming the European route E25), in particular the motorways serving Geneva (A40 of France) and Turin (A5 of Italy). The passageway is one of the major trans-Alpine transport routes, particularly for Italy, which relies on this tunnel for transporting as much as one-third of its freight to northern Europe. It reduces the route from France to Turin by 50 kilometres (30 miles) and to Milan by 100 km (60 mi). Northeast of Mont Blanc's summit, the tunnel is about 15 km (10 mi) southwest of the tripoint with Switzerland, near Mont Dolent.

The agreement between France and Italy on building a tunnel was signed in 1949. Two operating companies were founded, each responsible for one half of the tunnel: the French Autoroutes et tunnel du Mont-Blanc (ATMB), founded on 30 April 1958, and the Italian Società italiana per azioni per il Traforo del Monte Bianco (SITMB), founded on 1 September 1957. Drilling began in 1959 and was completed in 1962; the tunnel was opened to traffic on 19 July 1965.

The Autostrada A5 or Autostrada della Valle d'Aosta ("Aosta Valley motorway"), in French Autoroute de la Vallée d'Aoste, is an autostrada (Italian for "motorway") in Italy located in the regions of Piedmont and Aosta Valley, which connects Turin to France via Ivrea and Aosta, through the Mont Blanc Tunnel. It is a part of the E25, E64 and E612 European routes.

Ranked among the most advanced motorways in the country, as it is equipped with special heating systems to prevent the formation of ice on the road surface, it is 143.4 kilometres (89.1 mi) long and is the most expensive motorway in Italy.

The A2 motorway is a motorway in the Netherlands. It is one of the busiest highways in the Netherlands. The road connects the city of Amsterdam, near the Amstel interchange with the Belgian border, near Maastricht (NL) and Liège (B), and the Belgian A25 road.

The route of the A2 motorway is shared with two major European routes. Between its start, at Amstel Interchange, near Amsterdam, and the Interchange Oudenrijn, near Utrecht, European route E35 follows the A2 motorway. From the Oudenrijn Interchange towards the Belgian border just south of Maastricht, European route E25 follows the route of the A2. Local and express lanes on A2 have different speed limits. The speed limit on express lanes is 120 km/h (75 mph) and locals is 100 km/h (~62 mph).
