Sierre-Est Roundabout Transformations
- Beginning April 7, two roundabouts east of Sierre will undergo transformations as part of the A9 motorway construction project.
- The Bois-de-Finges route will be closed during the construction period between Cité du Soleil and Souste, diverting traffic to the cantonal road.
- A second roundabout will be redeveloped, and the sidewalk south of the cantonal road will be extended to improve safety for cyclists along the cantonal cycle path.

Sierre, Switzerland — April 28, 2025
Beginning April 7, two roundabouts east of Sierre will undergo transformations as part of the A9 motorway construction project.
The Bois-de-Finges route will be closed during the construction period between Cité du Soleil and Souste, diverting traffic to the cantonal road. To accommodate the increased traffic volume, one roundabout will be converted into a “turbo-roundabout.” This design prioritizes traffic flow by predetermining exit routes based on entry points,enhancing fluidity and reducing accident risks.
A second roundabout will be redeveloped, and the sidewalk south of the cantonal road will be extended to improve safety for cyclists along the cantonal cycle path.
The project is expected to last 20 months and cost 3 million francs. Completion is scheduled for the end of 2026, paving the way for structural work in Bois-de-finges.

Sierre, Switzerland — April 28, 2025
This article answers your frequently asked questions about roundabout transformations and their impact, specifically focusing on the projects east of Sierre, Switzerland.
Frequently Asked Questions About Roundabouts
What is a roundabout?
A roundabout is a type of circular intersection designed to improve traffic flow and safety. Vehicles entering a roundabout must yield to traffic already circulating within it.
Why are roundabouts being transformed east of Sierre?
The roundabout transformations are part of the A9 motorway construction project. These changes are necessary to accommodate increased traffic volume due to the concurrent closure of the Bois-de-Finges route. The goal is to ensure efficient traffic flow and enhance safety during the construction period.
What types of roundabout transformations are planned?
- Turbo-Roundabout Conversion: One roundabout will be converted into a “turbo-roundabout.” This design predetermines exit routes based on entry points for enhanced fluidity.
This is designed to enhance traffic flow by predetermining exit routes based on entry points.This helps reduce accident risks.
- Redevelopment of a second Roundabout: The second roundabout will undergo general redevelopment to optimize traffic flow.
- Sidewalk Extension: The sidewalk south of the cantonal road is being extended to enhance safety for cyclists along the cantonal cycle path.
What are the main benefits of a turbo-roundabout?
Turbo-roundabouts enhance traffic flow and reduce accident risks because they predetermine exit routes, allowing drivers to plan their path ahead of time.
When will the roundabout transformations begin and end?
The projects began on April 7th. completion is scheduled for the end of 2026, with the entire project expected to last 20 months.
How much will the project cost?
the project is estimated to cost 3 million francs.
How do roundabouts generally compare to other intersection types?
While the article doesn’t provide direct comparisons, this type of roundabout offers several advantages over traffic lights, mainly through flow and reduced delay, In contrast to traffic lights. Modern roundabouts offer reduced average daily delay. Such as, at a modern roundabout average daily delay is less than five seconds.
How are cyclists considered in these projects?
The project includes the extension of the sidewalk south of the cantonal road, enhancing safety for cyclists on the cantonal cycle path.
