The Emergency Solution Connects Swiss Village in Minutes, Allows Transport of People and Supplies, and Operates Until the Bridge Reconstruction
Life in a mountain village in the Swiss Alps changed radically after landslides destroyed an essential bridge and left the community practically isolated. Without direct access by road, residents needed to find a quick alternative to maintain their daily commutes.
The answer came in the form of a community cable car built in just 5 months, capable of transporting people and food between the village and the nearest area with road access. The solution restored predictability to daily routines and avoided prolonged isolation.
The system went into operation on February 17, 2025, shortening a journey that previously took almost half an hour via an unstable secondary road.

Heavy Rains Destroyed the Bridge and Left Sarreyer Practically Isolated
The heavy rains of summer 2024 triggered landslides and debris flows in the Val de Bagnes, in the canton of Valais, hitting the bed of the Fregnoley River. The force of the water destroyed the bridge that connected the village of Sarreyer to the rest of the valley.
With the structure compromised, access depended on a longer forest road, subject to frequent closures and additional risks during winter. The situation affected essential transport for school, work, shopping, and medical care.
Faced with the risk of prolonged isolation, the community sought a solution that would work even with the unstable terrain.
A 500-Meter Aerial Link Replaced the Destroyed Road
The cable car connects Champsec to Sarreyer via an aerial line of 500 meters in length. The journey takes around 5 minutes, drastically reducing the daily commute time for residents.
The system operates with a single cabin for up to 8 people per trip, functioning on set schedules and providing free access. At the lower station, there is parking and a direct connection to the regional bus transport.
Even with limited capacity, the aerial link ensures continuous circulation while the definitive solution is not completed.
Reinforced Foundations and Deep Anchors Ensure Stability in an Unstable Area
The installation was designed as a temporary cable car, with an expectation of operating for several years. The setup includes a lower station, central support tower, and upper station, all anchored in robust foundations.
The structures utilize vertical piles, deep anchors, and massive concrete bases, allowing them to withstand constant forces even in land affected by landslides. The anchoring of the main cable has been sized to ensure ongoing safety.
This type of solution reduces ground interventions and accelerates deployment in sensitive mountainous areas.
Reconstruction of the Bridge Will Take Up to 24 Months and Requires a More Complex Project
The reconstruction of the bridge requires a more elaborate project due to the geological conditions of the region. The new structure is expected to have a span of about 100 meters, well above the previous bridge, with an estimated timeframe of 18 to 24 months.
The cable car was executed in a much shorter timeframe and has been functioning as an interim solution. It allows the community to continue operating normally while the definitive project progresses.
This option also reduces risks during winter when direct interventions in the riverbed become more dangerous.
Daily Access Became Predictable for Residents, Students, and Workers
With the cable car in operation, residents regained reliable daily access, including for children attending school and workers who depend on fixed schedules.
The transport of food and essential supplies resumed regularly, avoiding prolonged isolation. The connection with buses at the lower station facilitates integration with other locations in the valley.
Even temporary, the structure brought stability to the local routine.
Cable Car Will Operate Until the Bridge Is Finished and Can Be Dismantled Afterwards
The cable car is expected to remain active until the new bridge is completed and opened for traffic. After that, the aerial structure may be dismantled or repurposed according to the decision of local authorities.
The experience shows how direct and well-designed solutions can keep communities active in the face of increasingly frequent extreme weather events in mountainous regions.
This case also reinforces that light and quick infrastructure can be crucial to avoid total isolation of small populations.
