Connects two railway tunnels: the Boßler and Steinbühl tunnels

Tonnes of structural steel
It was needed for the movable scaffolding system and auxiliary supports for the solid bridge.
Complex planning
- The new Stuttgart–Ulm line crosses the Filstal valley between the Steinbühl tunnel and the Boßler tunnel. The 472 and 485 m long semi-integrally designed structures cross the Filstal valley at a height of approx. 80 m with a main span of 150 m and connect directly to tunnels on both sides
- The structures were built with an overhead travelling scaffold and with up to 80 m high steel auxiliary supports as a box girder cross-section. The angled supports of the Y-columns are subsequently concreted and monolithically connected to the superstructures.

Extraordinarily high demands on planning, work preparation, and construction:
- The high axle and brake loads
- The future line speed of 250 km/h
- A superstructure with carriageway in combination with the concept of a semi-integral bridge, the Y-supports with flat diagonal braces, and the difficult topographical and geotechnical constraints
“The Filstalbrücke makes an important contribution to the innovative and aesthetic development of railway bridge construction. The slender and transparent building blends perfectly into the landscape and is already considered a new landmark in Baden-Württemberg”.
Peter Kotz, Head of Execution Planning for Road/Railway Engineering Structures in Munich
Efficient planning processes through BIM
The Filstalbrücke is one of the four BIM pilot projects of the Federal Ministry of Transport and Digital Infrastructure (BMVI):
- 4D construction sequence and status message, visualisation of individual objects in the manufacturing process
- Connection of the plan management platform (EPLASS) to BIM applications
- Link between the 3D model and the associated plans at the component level
- Integration and tracking of the planned run status in the 3D model
