Gotthard Road Tunnel

The Gotthard Road Tunnel in Switzerland runs from Göschenen in the canton of Uri at its northern portal, to Airolo in Ticino to the south, and is 16.9 kilometres in length below the St Gotthard Pass, a major pass of the Alps. At time of construction, in 1980, it was the longest road tunnel in the world; it is currently the ninth-longest. Although it is a motorway tunnel, part of the A2 from Basel to Chiasso, it consists of only one bidirectional tube with two lanes. With a maximum elevation of 1,175 metres at the tunnel's highest point, the A2 motorway has the lowest maximum elevation of any direct north-south road through the Alps.
The tunnel rises from the northern portal at Göschenen ) and the culminating point is reached after approximately 8 kilometres . After two or three more kilometers, the border between the cantons of Uri and Ticino is passed; after another 7 kilometres , the tunnel ends at the southern portal near to Airolo ). The journey takes about 13 minutes by car, the maximum speed being 80 km/h.
