Autigny suspension bridge: engineering, suspension ropes and Webnet
The suspension bridge over the Glâne River was planned and built by apprentices from various branches. Jakob Rope Systems supplied the statics as well as the suspension ropes and Webnet stainless steel nets.
A new pedestrian bridge between Autigny and Posat was planned and installed by apprentice metal construction designers, metalworkers, surveying technicians and bricklayers from the canton of Fribourg. The project allowed the young professionals to develop their professional practice and interdisciplinary collaboration.
Swiss associations, partners and sponsors made this bridge construction project possible. The bridge will be opened in spring 2025.
Jakob Rope Systems was allowed to create the statics for the suspension bridge. We were also able to supply the supporting ropes and Webnet stainless steel nets.
The construction: The suspension bridge consists of 4 supporting ropes (2 ropes below and 2 ropes above, OSS diameter 22 mm with Forte fittings), which are connected to each other with 4 steel frames. The integrated, statically activated Webnet (diameter 2 mm, mesh size 40 mm) serves as a railing filling and load-bearing element that connects the walkway of the suspension bridge to the upper supporting ropes.
The dimensions: The suspension bridge has a span of 23 meters and is 2,30 meters wide. It provides a connection (across the Glâne river) for the Way of St. James from Autigny to Posat and vice versa.

A new suspension bridge for St. Moritz: Jakob Rope Systems was commissioned to plan, supply and install the lightweight structure made of steel ropes and Webnet. Another bridge construction project in which our Webnet is integrated as a safety and load-bearing structure.
With the new rope bridge on the Balmberg, Jakob Rope Systems was entrusted with the factory planning, delivery and installation of a lightweight structure made of steel ropes and Webnet. The bridge construction is durable and blends discreetly into the rocky landscape of the Jura Höhenweg.
