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 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 at the tunnel's highest point, the A2 motorway has the lowest maximum elevation of any direct north-south road through the Alps.
