List of tunnels in the Alps

There are a large number of tunnels in the Alps of Central Europe. They have the advantage of providing shorter routes and faster journey times by avoiding narrow, winding routes over mountain passes which may well be affected by winter conditions. This list is intended to give an overview of the main Alpine tunnels. As the list is "country" oriented, cross-border tunnels are listed twice (e.g. the Mont Blanc tunnel is listed under France and under Italy.)

See separate article for a list of the longest tunnels in the world.
