What is the Katschberg Tunnel?
The Katschberg Tunnel, opened for traffic in 1974, is a border tunnel located south of central Austria on the Tauern Autobahn, connecting the regions of Salzburg (south of Oberweißburg, Unterweißburg, and Höf) and Carinthia (north of Saraberg and Mühlbach), running on the A 10.
In December 2004, construction began on a second tunnel tube. This was completed in April 2008, and the second tube was opened for traffic.
After the construction, the western tube is 5,565 meters (5.5 km) long and the eastern tube is 5,898 meters (5.8 km) long.
The Katschberg Tunnel is a so-called special toll section, which means that the Katschberg Tunnel is exempt from the vignette requirement. Therefore, additional fees apply for using the Katschberg Tunnel, even if you already have a vignette or have paid the section-specific toll.
