Lapendenta Suspension Bridge In Disentis

Since November 2024, Graubünden's longest suspension bridge has spanned the Rhine Gorge near Disentis/Mustér. The ARGE Jakob Rope Systems, Pfeifer and Von Rotz & Wiedemar AG realized this bridge construction project using rope technology and stainless steel construction.

Graubünden's longest suspension bridge has been open in Disentis/Mustér since November 2024. With a length of almost 300 meters and a ground clearance of 100 meters, the suspension bridge creates a spectacular footpath from Mumpé Medel to Disentis/Mustér over the narrow, deep Rhine Gorge here. From a tourist point of view, the suspension bridge connects two waypoints of the historic mule track over the Lukmanier Pass.

The ARGE Jakob Rope Systems / Pfeifer / Von Rotz & Wiedemar AG planned and built the complete solution for this suspension bridge.

Jakob Rope Systems designed the construction of the suspension bridge. The bridge structure consists of six suspension ropes (Ø 45 mm, VVS) below the walkway and two suspension ropes at handrail level. Two ropes (Ø 26 mm, Forte-OSS) are used for bracing. A bracing structure consisting of stainless steel ropes and connections reduces unwanted swinging during use, absorbs forces caused by wind and prevents major deformations.

The steel frame construction of the bridge girder is suspended from the supporting ropes. The stainless steel Webnet with a height of 1.30 meters provides the necessary fall protection as a side railing infill and also carries loads.

Bridge structure:

4 suspension ropes (Ø 45 mm, VVS) below the walking level, 2 suspension ropes (Ø 45 mm, VVS) at handrail level

Bracing:

2 ropes (Ø 30.9 mm, OSS), coupling ropes Ø 12 – 19 mm

Railing infill:

Webnet, 2 mm rope diameter, 60 mm mesh width, vertical meshes
