The Pfänder Tunnel is located in the far northwest of Austria, on the A14 between Leiblach and Bregenz/Kennelbach. It serves, among other things, to bypass the capital of the state of Vorarlberg, Bregenz. The tunnel passes under the 1064-meter-high Pfänder mountain. It connects the A96 from Germany with the Rheintal Motorway A14 in Austria. Holidaymakers looking for a quick route from Germany to Austria will reach their destination faster this way. The Pfänder Tunnel consists of two tubes. The east tube is 6,718 meters (6.7 km) long. The west tube is 6,744 meters (6.7 km) long.
Measurements in 2008 showed that more than 27,000 vehicles per day passed through the Pfänder Tunnel. By 2020, that number had increased to more than 30,000 vehicles daily. These figures show that the tunnel construction has had the intended effect of reducing traffic congestion in Bregenz.
Since 2019, the vignette requirement for motorcycles and cars under 3.5 t maximum permissible weight (tzGm) has been lifted for the Pfänder Tunnel. For vehicles over a total weight of 3.5 t tzGm, a distance-based toll still applies and must be paid using a GO-Box.
