Construction
Planned as a two bore tunnel from the beginning, the first bore of the Tauern Road Tunnel was completed in 1975 with a total length of . Plans for the construction of the second, parallel tube were abandoned in 1988 and not resumed until the 1999 fire disaster (see below).
1999 fire
On 29 May 1999, about 4:50 a.m., an accident in the tunnel led to a fire in which twelve people were killed and 42 injured. Caused by a collision of up to 60 individual vehicles, the incident occurred when a truck collided with a column of stationary vehicles waiting at a traffic signal. As far as investigators could determine, eight people were killed by the force of the collision of the truck while four further victims died from the fire which followed, exacerbated by escaping fuel and hazardous materials on one of the vehicles involved. All of the victims were burned to the point of leaving skeletal remains at most, and for those in more intense areas of the fire, nothing more than ashes.
The tunnel was so badly damaged by the heat from the fire that it had to be closed for three months for repairs during which major work was undertaken to improve the barriers, tunnel walls and ventilation system. A memorial service for the victims of the fire was held in the municipality of Flachau before the tunnel was officially reopened on 28 August 1999.
Extension

Works on the second tube began in July 2006; completed on 30 April 2010, they were followed by a general refurbishment of the older first bore. The two-tube tunnel was officially opened with a ceremony on 30 June 2011.
Today the Austrian Tauern Autobahn is an important north-south transport route through the
Eastern Alps connecting
Germany with
Italy and
Slovenia. In 2013, the average daily traffic passing the tunnel was about 18,000 vehicles, a quarter of which were large goods vehicles and trucks. The toll is 6
euros per car; a journey through the Tauern Tunnel and the adjacent
