The Vienna International Center junction is located at the west portal of the tunnel, the Reichsbrücke junction in the tunnel and the Kaisermühlen junction at the east portal. The passage through the Kaisermühlen tunnel usually takes around two minutes. The tunnel has two structurally separate tubes with three lanes each and a hard shoulder. As is customary on city highways in Vienna, a speed limit of 80 km / h for passenger cars and 60 km / h for trucks over 7.5 tons applies in the tunnel .
Section Control
Section control for speed monitoring was introduced in the Kaisermühlen tunnel on September 1, 2003 as the first stretch of road in Austria . The road operator ASFINAG sees the success confirmed by the fact that no more serious accidents have happened in the coming years and that the speed will practically not be exceeded.
