So, there was a need for action. A new safety system needed to be found – unobtrusive, attractive and yet effective. What made things more difficult was that there were no plans or information on the statics of the viaduct. After a bit of deliberation, a decision was ultimately made to use a safety net construction from the Swiss company Jakob Rope Systems. The enterprise from Trubschachen offers high-quality stainless steel ropes and safety technology with an attractive appearance as one of their specialities. The Webnet products in particular – extremely adaptable net constructions with a comparatively unobtrusive appearance requiring minimal maintenance over the course of decades – were deemed ideal for the bridge project.
In the end, safety nets made of the Webnet material were installed three metres below the bridge roadway on both sides of the bridge. They were supported on each bridge pillar by one strut and were stretched out horizontally on an additional bar extending three metres out. Due to its transparency, the construction does not hinder the incidence of light or existing lines of visual connection. The fact that the mesh size and the loading capacity of the net structure are variable proved to be advantageous for the project. This is because not only suicide attempts were to be prevented at all costs, but also jumps “for the fun of it” and ill-conceived tests of courage as well.
