history
With the completion of the west tube of the Ambergtunnel and the handover of traffic on July 16, 1985, the Rheintal Autobahn was continuously passable, but in the area of the two large tunnels this was initially only possible with two lanes in oncoming traffic until December 2003. In the first year of operation, the Ambergtunnel had to cope with an average daily traffic volume of 10,000 vehicles. By the end of the millennium, however, the traffic figures had risen dramatically and traffic jams in front of the portals were not only common on the ski weekends until the second tube was built. In 2001, the Ambergtunnel used an annual average of 23,000 vehicles per day, of which 2,400 were trucks. The highest measured daily exposure was even 38,000 vehicles.
Since the tunnel, with up to 38,000 vehicles per day, was one of the most heavily loaded single-tube tunnels in Austria, a second tube ("east tube") was added in 2003, so that a total of four lanes are now available. The cost of the eastern tube amounted to 49 million euros and was opened on December 16, 2003.
