San Bernardino Tunnel in Switzerland – everything you need to know

The Swiss San Bernardino Tunnel stretches over a length of 6.6 km and provides a vital connection between the Hinterrhein in eastern Switzerland and San Bernardino in Ticino. The N13 national road, which runs through this tunnel, is considered the second most important Alpine crossing in Switzerland, second only to the Gotthard Tunnel. The route opened in 1967 and was extensively renovated between 1991 and 2006. An interesting fact is that migratory birds now also use this tunnel. Occasionally, traffic must be stopped so that the birds can continue their flight undisturbed.

The most important things in brief:

• The San Bernardino Tunnel is 6,600 meters long.
• The tunnel will connect the Hinterhein region in eastern Switzerland and San Bernardino in Ticino.
• The tunnel is toll-free, so you only need the normal annual vignette.
