The A1 is a motorway in Switzerland. It follows Switzerland's main east-west axis, from St. Margrethen in northeastern Switzerland's canton of St. Gallen through to Geneva in southwestern Switzerland. The motorway spans over 200 kilometres (120 mi) through Switzerland.
With the build of the third Baregg Tunnel tube,[clarification needed] the traffic jams in this area were reduced, but the Gubrist Tunnel remains with the old capacity as a new point of heavy traffic.[clarification needed][citation needed]
