The West Autobahn (A1) was the first motorway (Autobahn) to be built in Austria, originating from plans drawn up for the so-called Reichsautobahn system. Completed in 1967, today it runs from the outskirts of Vienna via Linz to Salzburg, where it joins the German Bundesautobahn 8 at the Walserberg border crossing. The A1 is Austria's main east-west thoroughfare and part of the major European routes E55 and E60.
