Herrenkrugsteg, Magdeburg

The Herrenkrugsteg is a bridge that spans the Elbe River and the embanked foreland as well as the lock canal in the north of Magdeburg. The structure, which is s-shaped in plan, connects Herrenkrugpark on the east side with the district of Magdeburg-Industriehafen to the west. The foot and cycle path bridge was built on the occasion of the 1999 Federal Garden Show.

The bridge train, which is 615 m long in total, consists of an unusually designed, 250 m long suspension bridge in the river area, which spans the Elbe with a center span of 145 m. The superstructure is supported by two 27 m high pylon stems consisting of three steel tubes arranged in a triangle, which are connected at five points and converge at both ends. The inclined pylons are arranged alternately offset to the side of the superstructure and braced at the head by cables. The weight of the superstructure is suspended from two 12 cm thick suspension cables that run over the pylons and are anchored back in the next pier head.

The superstructure of the suspension bridge with a 3.9 m wide deck has a 30 cm thick and 5.3 m wide reinforced concrete slab. This consists of 15 cm thick semi-precast elements, which were delivered via the Elbe, hoisted and attached to the hangers, and a 15 cm thick in-situ concrete layer.
