The tracks run over the river at a height of 30 meters and a length of 313 meters; 24,400 cubic meters of quarry stone and 12 arches with a span of 20 meters each are required. The structure describes a slight curve with a radius of 380 meters. The bridge deck with the tracks on it has a gradient of 0.5 percent.
In 1879 the line was inaugurated as a section of the Düsseldorf-Derendorf-Dortmund Süd railway line ("Rhenish route") of the former Rheinische Eisenbahn-Gesellschaft - a technical masterpiece for the time. The construction of the viaduct in the dimensions described was necessary in order to be able to keep the length of the Ender Tunnel as short as possible in the further course of the route . The increase in the associated railway line began at the southern foot of the Kaisberg with one percent; the desire of the planning engineers for a right-angled crossing of the Ruhr valley led to a winding design of the entire route on this section. The nearby Ruhr sandstone was used for the construction.
In May 1943 a pillar of the viaduct was torn away by the following tidal wave when the Möhne barrier wall was destroyed by Operation Chastise . An approaching passenger train was able to stop just 20 meters from the gap.
In 1945 two arches of the building were blown up by the Wehrmacht . The viaduct was not rebuilt until 1952, whereby it had to be straightened because the entire viaduct had been affected by the collapse of the vaults during the war destruction. It was not until 1957 that the first trains were able to cross the viaduct.
Anyone who takes the Volmetal Bahn on the route from Hagen to Herdecke today still crosses the Ruhr on the old route and can enjoy the view. At the southern end, one can see the foundation of an anti-aircraft position , with which one the viaduct in World War II against air strikes wanted to protect.
