The Griethausen railway bridge , also Altrheinbrücke called in Kleve-Griethausen is the oldest surviving bridge of the railroad of the German section of the Rhine and is under monument protection .

history

It was 1863-1865 by the Rhenish Railway Company with the establishment of the Lower Left Rhine Railway from Cologne via Neuss, Krefeld and Kleve on the Dutch North Sea - ports under the direction of Emil Hermann Hartwich built and led over a dead arm of the Rhine in the direction of Elten and on to Zevenaar in the Netherlands . The Rhine stream was crossed with a trajectory .

description

Main bridge Altrheinarm - box-shaped steel truss bridge made of puddle steel
Griethausen railway bridge, flood openings

The entire bridge structure extends over a length of around 484.4 m and consists of a main opening with a span of 100 m over the Old Rhine and twenty simple truss girder bridges over the wide flood bed .

The main bridge has a wrought iron superstructure with two parallel-chorded girders, in which the lattice girder that was customary up to that point was further developed. The close-meshed, cross-mounted bars are only used in the middle part, where both tensile and compressive stresses occur. In addition to the posts, only one-way struts were used in the outer parts. The strongest iron profile on the main bridge was an angle profile measuring 110 mm × 110 mm × 15 mm and sheet metal measuring 5,100 mm × 1,750 mm × 10 mm. These materials explain the very delicate construction of the bridge by today's standards. The material used for the bridge is also remarkable, as the wrought iron produced using the puddle process is characterized by a very low carbon content and a high phosphorus content . In combination with a small amount of copper and nickel, both of these influence the corrosion resistance of the material with the effect that the bridge practically does not rust , although the last protective coating was applied in the second half of the 1920s. The corrosion protection of the phosphorus- alloyed weatherproof structural steels produced today works in a similar way: Under the rust layer, weatherproof steels form a thin barrier layer of firmly adhering phosphates or sulfates, which gives the material its resistance to weathering.

While the trajectory over the Rhine was discontinued in 1912, passenger traffic over the bridge to Griethausen continued until 1960, goods traffic to an oil mill in Spyck directly on the Rhine until 1987. After that, the line including the bridge was closed. For some time now, considerations have been given to creating a cycle path along the entire bridge . Their excellent state of maintenance would make the project very inexpensive.
