Visualisation of the Zweite Hinterrheinbrücke with the existing bridge in the background.
The ground was broken for construction of a new
COWI-designed railway bridge in Reichenau, Switzerland on 29 May 2017.
The Rhaetian Railway is constructing the bridge over the Hinterrhein River to improve journey frequency on the Chur - St. Moritz and Chur - Disentis-Muster routes. It will also cross the adjacent A13 highway. The new bridge will be built alongside an existing 19th Century steel truss bridge which forms part of the Rhaetian Railway's historical Albula route, a UNESCO World Heritage Site.
The structure, known as the Zweite Hinterrheinbrücke (Second Hinterrhein Bridge), will be 200m long with a 63m span. The design features inclined strut supports, minimising the span to enable a very slender deck. The deck cross-section will consist of a pair of trapezoidal semi-through steel box girders with steel crossbeams and a steel deck.
The bridge was designed by a joint venture between COWI (formerly Flint & Neill) and WaltGalmarini AG in association with Dissing+Weitling Architects and Hager Partner AG Landscape Architects.
