On December 9, 2005, the Sunniberg Bridge was ceremoniously opened – the current British King Charles III and the then Federal President Moritz Leuenberger officially opened the bridge to traffic.
Exactly 20 years later, on December 9, 2025, the municipality of Klosters will celebrate the anniversary of its landmark.
To mark the occasion, the Sunniberg Bridge will be illuminated every evening for approximately one week – a sign of appreciation for this unique structure.
