Rügen Bridge is fitted with suspension cables using a system unique in Germany, whereby they are triple-protected from corrosion: first the cables are galvanized, secondly they are covered with a coating of polyethylene, and finally with special wax as well. The cables were tested for a year at the Technical University of Munich, and finally approved by the Federal Ministry. The steel cables, with a total mass of up to 135 tons, consist of 34 individual strands that are bundled into a sheath to form a single cable with a diameter of 180 mm. They are rated for a tension of 4000 kN.
