The Mahlbusen Bridge consists of two steel bridges. Both bridges are two-span continuous girders on pile foundations, one with asymmetric spans, the other with symmetric spans. The outstanding characteristic of the structure is the sliding height of the longitudinal girder, following the moments due to the dead load. This resulted in an intriguing, undulating girder and an optimal use of the materials. The longitudinal girders placed alongside of the slab are composed of stacked welded I- and T-profiles. The welded transverse girders are bending resistant, supporting the grids as pavement, and providing the horizontal bracing and buckling stability for the longitudinal girders.
