Swiss Geography
The geography ofSwitzerland is notable for its great diversity. Switzerland’s three main geographical regions are the Jura, Plateau and the Alps.

Transit and Traffic
Switzerland stands on theroute linking northern and southern Europe, but the Alps made transit difficult until tunnels were built through them. The Gotthard railway tunnel, 15 km (9.3 miles) long, was built more than 100 yearsago. The Gotthard road tunnel, opened in 1980, was the longest in the world at 17 km (10.6 miles) until Norway's Laerdal tunnel (24.5 km/15 miles) opened in November 2000.
