Weißbach near Lofer
Avalanche radar is armed from December
Detectors monitor two dangerous avalanche slopes in Weißbach near Lofer and send warnings directly to new traffic lights in the valley, which then switch to red.
The avalanche radar high above Weißbach with traffic lights on the main road is a first on Salzburg's roads. A test phase without traffic lights was carried out for a year. Now the system is going into full operation.
The monitoring system was flown up the mountain on Tuesday. Behind the system is complicated technology: the detectors recognize landslides at the Lahnerhorn and Wiesergalerie and send information about the location and extent to the traffic lights in the valley in the shortest possible time, which then switch from green to red. If the snow does not reach the road, the signal changes.
In operation from warning level 3
The system is activated from avalanche warning level 3, as Martin Harter from the Provincial Building Directorate informs us. Provincial geologist Gerald Valentin adds: "We want to massively reduce the closure times of the main road. There will no longer be day-long closures."
Another system is currently being tested above Tweng. There are no traffic lights in this area yet.
