The Grandfey Bridge is a masterpiece of engineering and spans the wide valley of the Saane between Düdingen and Fribourg.
The 343m long and 80m high bridge north of Freiburg was originally made of iron. For the heavier electric locomotives, the truss girders with the roadway above were no longer sufficient. The bridge was encased in concrete between 1925 and 1927: Iron arches were stretched between the supports and, like the truss piers, concreted in as reinforcement. Eight filigree concrete double supports on each of the arches carry the roadway.
Underneath is a spectacular pedestrian and cycle path, which is in regular use. The height and the vibrations of the passing trains make a walk through the bridge an impressive experience. At both ends of the pedestrian bridge is one of the most important works of minimalism in Switzerland. It was created in 1988 by the artist Richard Serra.
