Kuilenburg (Culemborg) Bridge
The original railway viaduct over the River Lek at Kuilenburg, Gelderland, Netherlands, was a remarkable structure built between 1863 and 1867.
It was replaced by the present bridge in 1982.
The original viaduct had seven spans of 60m, one of 85m, and one of 154.4m.
The most notable feature was the main bridge truss girder, constructed by Johann Caspar Harkort.
It is regarded as the first bridge to be built using steel for main structural members.[1]
The approach viaduct was constructed by Hüttengewerkschaft und Handlung Jacobi, Haniel & Huyssen.
