A2 motorway (Switzerland)

The A2 is a motorway in Switzerland. It forms Switzerland's main north-south axis from Basel to Chiasso.

The A2 motorway leaves Basel heading south toward Olten, Sursee, Luzern, Stans, Altdorf, Erstfeld, Göschenen, Airolo, Biasca, Bellinzona, Lugano and reaches Chiasso.

It intersects with the A1, A8, A13 and A14 motorways.

The St. Gotthard Tunnel lies on the way. Traffic jams stretching for kilometres on end are frequently found on both entrances of the tunnel, but more frequently on the northern flank. The difficulty with driving through the St. Gotthard tunnel is that it is a motorroad tunnel with one lane per direction, but without a central reservation. So far, plans for a second Gotthard tunnel have been rejected or otherwise failed to come to fruition.

Near Lucerne, this motorway passes through the Sonnenberg Tunnel, which until recently was the world's largest nuclear blast shelter.

This is one of the most driven-on motorways in Switzerland.
