Infrastructure and network length

Switzerland’s transport infrastructure is well developed in international comparison. It covers more than 2% of Switzerland’s territory and almost a third of its settlement and urban area. In 2023, the road network was  84 868 km long, with motorways accounting for 1549 km. At the time of the last survey in 2020, the railway network measured 5317 km.

In air transport, the three national airports Zurich, Geneva and Basel provide Switzerland with connections to European and global centres. Furthermore, a total of eleven regional airports primarily serve business, tourist and work aviation.

The Swiss transport infrastructure is completed by 126 km of cog railway lines, 316 km of tramlines, 1037 km of cable cars and 109 km of oil pipelines (60 km of which are inactive).

In terms of leisure traffic, hikers can enjoy a network of marked paths of around 66 000 km in length. Furthermore, there are about 12 000 km of uniformly marked and recorded cycle routes and 11 000 km of mountain bike routes.
