The Silvretta federal highway \u201eB 188\u201c is the main traffic axis in the heavily used Paznauntal in Tyrol (Austria). Previously, each year, the centralized road had to be closed more and more often, causing major problems in commuter and holiday traffic as well as transporting supplies to the Paznaun Valley. Several avalanche paths were secured in the 1950s by steel snow bridges or avalanche galleries in the run-off area, however the \u201eB 188\u201c was still endangered by avalanches from three avalanche lines in the municipal areas of Ischgl and Kappl, which repeatedly resulted in longer closures. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In a pilot project, avalanche towers<\/a> in combination with a Wyssen avalanche radar were considered to secure this critical road. For this purpose, six avalanche towers were installed in the area of the \u201eGrosstal avalanche\u201c and another two in the area of the \u201eHoher-Zug avalanche\u201c. The corresponding avalanche radar is positioned 1,800 meters (1.1 miles) away on the opposite side of the valley, directed towards the area where the \u201eGrosstal avalanche\u201c begins. With avalanche radar<\/a> both remotely triggered avalanches and spontaneous avalanches can be detected at any time of day or night and in any weather. As well the radar measurements are an integral part of the decision making process of the avalanche commission for the opening and closing of the road. Before the radar was put into operation, data from some avalanches had to be recorded in order to optimize the parameters of the radar\u2018s automatic alarm to the respective area. After this adjustment of the parameters and some additional localizations, the radar is calibrated and ready for use. An alarm signal is sent to the control panel and initiates the corresponding procedure. The compact design and independent power supply ensure reliable operation.
The same concept with three avalanche towers and an avalanche radar has also been installed in Kappl for the defusing of the \u201eUlmicherbachl avalanche\u201c.
Experience has shown that the combination of detection and remotely triggered avalanches can significantly reduce road blockages. Wyssen avalanche towers enable effective avalanche triggering with minimal impact on nature, while the radar reliably detects both manually triggered and spontaneous avalanche emissions. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
