As part of the planned A26 interstate connecting the A7 at Moorburg to the A1 at Wilhelmsburg, a competition was held for a Süderelbe crossing over the Elbe in the Moorburg district of Hamburg. The proposal elaborated by the joint planning venture won out in an international competition, where it was awarded first prize. Following the competition, the joint planning team was awarded the contract for the final design. The structure south of Kattwyk Bridge is a cable-stayed bridge built as an integral construction with a monolithic connection of bridge superstructure and supporting sub-structures. Two symmetrically configured, 140-metre-high pylons reference the city’s landmark, the Köhlbrand Bridge. The clearance height of the bridge is 55 metres, the same as that of the Köhlbrand Bridge. The bridge superstructure consists along a length of 392 metres of two separate box girders for the lanes in both directions. The boxes are connected to one another at regular intervals by cross-girders.
