Ground has been broken for the Cowi-designed Rhaetian Railway bridge in Reichenau, Switzerland.
The 200m structure will be known as the Second Hinterrhein Bridge and it will have a 63m span, which has been minimised for a slender deck. The design includes inclined strut supports and the deck cross-section will consist of a pair of trapezoidal semi-through steel box girders with steel crossbeams and a steel deck.
The first Hinterrhein bridge steel truss was built in the 19th century and is part of the Unesco-listed historical Albula rail route.
Cowi has designed the bridge over the Hinterrhein River to improve journey frequency on the Chur to St. Moritz and Chur to Disentis-Muster rail lines, as well as crossing the A13 highway.
The bridge was designed by a joint venture between Cowi and WaltGalmarini AG in association with Dissing+Weitling Architects and Hager Partner AG Landscape Architects.
