Securing the tourist route on Strynefjellet

Home page Projects Securing the tourist route on Strynefjellet

The tourist road over Strynefjellet will be opened as soon as possible. Large landslides from Stavbrekka are the challenge. Cautus Geo monitors, warns and can close the popular road to protect lives.

Problem statement

The tourist road over Strynefjellet is closed in winter. Innlandet County Council wants to open the road as early as possible every spring. The challenge is that every year there is a large landslide from Stavbrekka. This buries the tourist route under large amounts of snow.

Solution

Ground-based InSar radar monitors the snow at Stavbrekka. Throughout the day, the snow masses are documented in a 2D model with an accuracy of less than a millimetre. When the speed of movement in the snow increases, an alarm is triggered and the road is automatically closed with a light signal. It is controlled automatically from Cautus Web.

Large landslides every year

Cautus Geo has been radar monitoring the snow at Stavbrekka since 2019. Avalanches have been technologically documented every winter in recent years. The goal is to safely reopen the winter-closed road as soon as possible.

The tourist road between Lom and Geiranger is closed in winter. With radar monitoring, the road can be reopened earlier and without the risk of clearing crews and other road users being caught by avalanches.

Monitoring is automatic and continuous. Data is fed into Cautus Web. The data is analysed continuously and is always available. The system shows exactly what is happening on the mountain. When movements in the snow masses increase, the system sends out an alert and the road is closed.
