K27 Bristenstrasse - stage 2024, natural hazard measures section Bristen - St. Antoni
The K27 Bristenstrasse is a narrow, winding cantonal road. Apart from the few passing places, it is difficult for two vehicles to cross. The work and logistics must therefore be planned very carefully. All deliveries and transports must be carried out by 2-axle lorries with a weight limit of 18 tonnes. Exceptions require a request with special authorisation.
Construction of new protective measures against natural hazards for the cantonal road section of the Bristenstrasse between Amsteg and St. Antoni. The project includes the natural hazard measures in the implementation year 2024.
Installation of a 500 KJ rockfall protection system. Six such systems are being built. In the picture, the support poles have already been moved and the net will then be installed.
To ensure that the work can be carried out in rough terrain, safe access points are required, which are created using scaffolding tubes.
Working platforms are moved by helicopter so that the anchors and piles can be installed in the steep terrain. The platforms serve as a storage space for materials and inventory.
