Presentation

Ganslandsiepen Viaduct – manufacturing and assembly of a semi-integral viaduct

The new construction of the A44 motorway between the Ratingen-Ost interchange and the existing end of the A44 expansion in Velbert creates a continuous east-west link between the Rhine river and the central Ruhr area. A three-span bridge structure with individual span widths of 64 m – 80 m – 64 m and a total span of 208 m is being erected near Heiligenhaus as the Ganslandsiepen viaduct, creating an overpass above several rural roads and the Gansbach stream. The ravine is being bridged at a height of up to 35 m.
