Switzerland has a dense road and rail network. Over 2600 stations and stops make up the 24,500-kilometer public transportation network in Switzerland.

Because the Alps divide Northern Europe from Southern Europe, crossing the Alps is an important European transportation route. The Gotthard Railway and its central Gotthard Rail Tunnel marked the beginning of Alpine railway routes in 1882. The Simplon Tunnel opened in 1906, and the Lötschberg Tunnel opened in 1913. The Gotthard Base Tunnel opened on June 1, 2016, and the Lötschberg Base Tunnel opened in 2007 as part of the New Railway Link through the Alps.

Road tolls and vehicle taxes pay for the Swiss road network. In order to use the Swiss motorway system's roadways, both cars and trucks must purchase a road tax disc, which costs 40 Swiss francs per calendar year. As of 2000, the Swiss motorway network had a total length of 1,638 kilometers and one of the highest motorway densities in the world, covering 41,290 km2.

With 24.9 million passengers in 2013, Zurich Airport is Switzerland's largest international flight gateway. Geneva Cointrin, the second-largest airport, handled 14.4 million passengers in 2013, while Basel Mulhouse Freiburg, the third-largest EuroAirport, handled 6.5 million; the two air terminals are imparted to France.

For the purpose of improving the infrastructure for public transportation in Switzerland, billions of francs have been approved. In 2010, the modal split for public transportation was 21.3%, making it one of the highest in Europe[3]. In many cities with a population greater than 100,000, the modal split for public transportation is greater than 50%.
