Andorra Postpones Turboroundabout Trial to Spring Due to Snow
A pilot scheme to introduce lane-segregated turboroundabouts at two key Andorran junctions has been delayed from January until spring due to heavy.
Key Points
- Trial at Prada Casadet and KM0 roundabouts postponed amid persistent snow.
- Outer lane restricted to straight-ahead or right turns; inner lane for straight or left.
- Designed to prevent lane crossing, reduce crashes, and improve flow.
- Six-month test with signage; could become permanent and expand if successful.
A trial of 'turboroundabouts' at two key Andorran junctions has been postponed until spring due to persistent winter snow.
The pilot scheme, originally scheduled for January, will restrict the outer lane at the Prada Casadet and KM0 roundabouts—both for uphill and downhill traffic—to straight-ahead travel or right turns only. Mobility officials delayed the rollout amid challenging weather conditions, opting not to impose additional demands on drivers during heavy snowfall.
The measure aims to improve traffic flow and reduce collisions by segregating lanes: vehicles entering the inner lane will be limited to straight or left turns, while those in the outer lane can only go straight or right. This setup prevents vehicles from crossing paths, minimising crash risks and enhancing overall circulation efficiency.
Clear signage and driver instructions will accompany the trial, which is set to last at least six months. Mobility authorities are confident in its success and plan to make it permanent at these sites if it proves effective, with potential expansion to other multi-lane roundabouts critical to national mobility.
Implementation will follow the end of snowfalls, with spring markings to enable the test.
