Hansalinie Bremen rail overbridge
For the development of the Hansalinie industrial park in Bremen-Hemelingen, two railway overbridges were built. Crossing of the DB line 1404 takes place here at km 6.8 + 182.

The two transferred tracks are located at different heights, approx. +12.19 m NN on the north side and approx. 10.14 m NN on the south side. The terrain level is approx. 6.00 m above sea level. Due to the different track heights, the distance between the tracks is so great that a track slab was not feasible. Two railway bridges were built alongside each other.
Sheet piling was driven into the railway embankment to construct the substructures. In addition to securing the embankment, these were also used to support 4 x ZH 9 auxiliary bridges with a span of 24.00 m each. DB AG required and carried out extensive monitoring of the auxiliary bridges. After the excavation, the bridges received a bored pile foundation, on which the abutments were placed. The tracks were constructed parallel to the railway embankment and installed after completion of the abutments.
