About Landwasser Viaduct
The Landwasser Viaduct (Landwasserviadukt) is one of Switzerland's most breathtaking engineering marvels and a globally recognized symbol of the Rhaetian Railway (RhB). Soaring 65 meters (213 feet) above the rugged Landwasser Gorge, this curved, six-arch limestone structure spans an impressive 142 meters in length before dramatically disappearing directly into the sheer rock wall of the Landwasser Tunnel.
Part of the legendary Albula Railway line, the viaduct was constructed between 1901 and 1903 without the use of scaffolding, relying instead on two crane towers anchored into the stone pillars. Today, it forms an integral section of the UNESCO World Heritage Site 'Rhaetian Railway in the Albula / Bernina Landscapes'.
Experiencing the Viaduct
Visitors can experience this architectural masterpiece in two primary ways:
- By Rail: Boarding the famous Glacier Express or Bernina Express offers an unparalleled perspective as the train curves around the high bridge, delivering sweeping alpine views right before entering the tunnel.
- On Foot: A network of well-maintained hiking trails leads from Filisur train station directly to two panoramic viewing platforms (North and South outlooks), as well as down into the valley floor right beneath the towering arches.
History
Designed by chief engineer Alexander Acatos and built by the construction firm Peter Brizzi, work on the Landwasser Viaduct began in March 1901. Constructing a high-altitude railway line through the challenging terrain of the Swiss Alps presented monumental logistical and structural hurdles.
Innovative Construction Techniques
Unlike standard bridge projects of the era, traditional timber scaffolding was ruled out due to the risk of spring floodwaters carrying away support beams in the deep gorge. Instead, workers built the masonry pillars using iron scaffolding integrated directly into the core of the masonry structures, raising the stone blocks using steam-driven cranes.
Key Historical Milestones
- 1901: Construction commences on the limestone piers.
- 1902: The dark limestone arches are completed and the track bed is laid.
- October 1903: Official opening for regular train services on the Albula Railway line.
- 2008: Designated a UNESCO World Heritage Site alongside the Albula and Bernina railway routes.
- 2009: Underwent a comprehensive, multi-million franc restoration while train operations continued uninterrupted over the bridge.
