The Aller Bridge is an innovative replacement of the old railway bridge along the line Wunstorf-Bremerhaven. The dual track DB railroad line runs through picturesque countryside and the bridge harmoniously integrates itself with the landscape.
It is a continuous, slender design, using materials appropriate for the moment-diagram formed webs which are connected on both sides with the orthotropic steel deck. The web stiffeners are arranged in a fan-shape structure to follow the flow of forces around the main span.
The height of the outer steel girders remains constant and the web stiffeners are arranged purely vertically to create a harmonious alignment with the approaching ramps.
The bridge’s superstructure is supported by bearings on the slender pier walls and abutments, with the fixed point in the longitudinal axis located on the Northern pier. The construction is assembled with an incremental launching method of eight sections.
We are proud of our conceptual and construction design of this 8-span steel trough bridge.
