Excerpt from a message from the "Interessengemeinschaft Westerwald-Querbahn (IWQ) e.V.":
"The steel lattice bridge near Fehl-Ritzhausen is a particularly interesting example of a so-called fish-belly girder bridge, technical term "parabolic steel truss bridge".
It consists of two differently sized abutments made of local blue basalt with a steel lattice girder suspended between them.
The arched girder hangs downwards, which is why it is commonly referred to as a "fish-belly girder bridge". Traditionally, bridges were built with their latticework up. Only in rare cases, i.e. where there was enough height, was the support structure moved downwards on railways. In addition, the reason whether a profile restriction had to be accepted for a route or not was also decisive. The bridge at Fehl-Ritzhausen is today the only bridge in the Westerwald area that was built in 1906 as a so-called "Fischbauchträgerbrücke".
Technical specifications:
The south abutment is approx. 5 m long, the north abutment approx. 15 m. Round iron railings are attached to both abutments. The bridge girder is approx. 30 m long. The height above the stream bed is about 18 m. The railing is made of angle steel."
