The S-Bahn crossing in Stuttgart’s new underground railway station spans a lower existing tunnel that runs at right angles to the new tracks. The bridge structure rests on bored pile walls, with chalice supports with shell roofs forming the upper end. Due to the enormous load-bearing capacity of the structure and its limited accessibility during operation, the planners had to introduce various technical innovations to make the project feasible.
A detailed documentation of this demanding project has now been published in the magazine “Bautechnik”. The article can be downloaded here as a digital offprint.
