Remote Avalanche Control System for public road in Norway
|Project:||Securing County Road 53 Tyin - Årdal by avalanche towers|
|Place:||Tyin, Oppland County|
|Customer:||Norwegian Public Road Administration (NPRA)|
|Installed systems:||- 14x Wyssen Avalanche Towers LS12-5 - 1x Weather Station - WAC.3®|
The county road 53 Tyin – Årdal, is in Oppland county on the border to Sogn & Fjordane in Norway. It’s an important road for the inner parts of the Sogn region and especially the local community Årdal. A large part of the road is located above tree line, which makes it very exposed to winter storms and avalanche hazard:
Avalanche Control in Norway
In Norway, avalanche protection has traditionally been carried out with permanent measures such as tunnels, dams, snow sheds or snow fences. These measures are very effective, but the investment and running costs are often very high and the environmental impact is considerable.
Testing Wyssen Avalanche Tower at Road 53 Tyin - Årdal
In 2010 the Norwegian Public Road Administration (NPRA) decided to test a Remote Avalanche Control System (RACS) at the county road 53 Tyin – Årdal in Oppland County. A Wyssen Avalanche Tower was installed in one of the many avalanche paths threatening the road to test out whether the system would perform in tough Norwegian winter conditions with strong winds, low temperatures and almost no daylight during the winter months. The two year test-project was very successfull.
Based on this the NPRA and Oppland county decided to install RACS at all avalanche paths along the road to mitigate the avalanche hazard along the road. The project was announced January 2016 and several suppliers delivered offers.
