Slope Stability - Tamina Bridge 2013

With its 265 meters span, the Tamina Bridge is one of the largest arch bridges in Europe

Slope Stability - Tamina Bridge 2013

High tensile steel drapes made out of TECCO® and DELTAX® mesh came first: thus protecting the road during the construction phase and allowing to build the bridge

Slope Stability - Tamina Bridge 2013

The bottom border ropes are placed ca. 50 centimeters above the protected road which enables easy maintenance

Slope Stability - Tamina Bridge 2013

High tensile steel mesh TECCO® G65/3 is nearly invisible on the slopes

Slope Stability - Tamina Bridge 2013

High tensile steel mesh TECCO® G65/3 is nearly invisible on the slopes, especially when partially covered by vegetation

Slope Stability - Tamina Bridge 2013

Visible top border rope anchored by 3.0 to 4.0 meters long wire rope anchors installed between 3.3 to 3.5 meters between each other

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.
