The Horremer Brücke is a railway bridge in the course of the North-South Railway , with which RWE Power (formerly Rheinbraun ) transports lignite and overburden between the various opencast mines , lignite power stations and other facilities in the Rhenish lignite area.
It crosses the cut in the ridge of the Ville , which was created by the demolition of the Königsdorf tunnel in what is now the four- track Cologne – Aachen railway line .
The double-track bridge was built by Dyckerhoff & Widmann in 1953 and 1954 according to a design by Ulrich Finsterwalder . It was one of the first prestressed concrete railway bridges .
It is a total of 193 m long and 12.40 m wide. The main bridge, designed as a truss , is 143.80 m long and has a span of 86.80 m. It has two parallel, slightly haunched box girders , which are divided into sections of 39.90 + 64.00 + 39.90 m by the struts . Constructively, it is a five-fold, statically indeterminate three-field frame with a box cross-section.
The bridge has been strengthened in recent years with an external steel corset.
Immediately to the east of the bridge, a bridge is to be built for the planned Königsdorf bypass. After the installation of a temporary protective cover over the tracks of the Cologne – Aachen line, concerns arose that this bridge could endanger the stability of the Horrem Bridge, which is why construction was initially discontinued.
