Initial situation
The villages of Valens and Pfäfers are in the Swiss Canton of Grisons. They are separated by the deep Tamina valley. The Valensstrasse connects Bad Ragaz with Valens and runs along the left side of the valley. It is primarily located in an active landslide area. There have been problems at the Valenserstrasse for many years due to difficult geological conditions. Smaller and larger slides, including rockfalls occured regularly. The road no longer met the requirements of administration. Their solution was visually unobtrusive, fully safe and allowed the Tamina Bridge to be officially opened in summer 2017.
We have taken information from the German website of the Civil Engineering of the Canton of St. Gallen.

Description
During the construction phase, the Valenserstrasse had to be protected as an access road that later became the Tamina Bridge. The mesh which was installed in early 2013 not only meets the safety requirements of the road authorities, but perfectly integrates into the landscape. The TECCO® wire mesh is barely visible on the gray rock or under vegetation. An ideal solution for the Tamina valley with its scenic beauty and ecological value.
