ARGE Flughafentunnel

ARGE Neubaustrecke Flughafentunnel - Engineering at the highest level for an efficient infrastructure

A central component of this mammoth project is the approximately 5.3 kilometer long section in the area of Stuttgart Airport - a highly complex interplay of civil engineering, tunnel construction, track construction and extensive road infrastructure measures. The consortium ARGE Neubaustrecke Flughafentunnel, consisting of ZÜBLIN, Max Bögl and STRABAG, was responsible for the planning and execution of this challenging section. The consortium was supported by other central ZÜBLIN units such as Central Engineering, Special Civil Engineering and Züblin Umwelttechnik GmbH - a perfect interplay of interdisciplinary expertise.

Lot VE 10 light (Lot 1)

The VE 10 light paving lot forms the heart of the overall project and combines several technically sophisticated structures into one central infrastructure component. Along the A8 federal highway, a new above-ground section of around three kilometers in length will initially be built to ensure an efficient connection to the other sections of the new Stuttgart-Ulm line. At the heart of the lot is the construction of a twin-tube, single-track airport tunnel, which, including extensive trough structures, has been precisely integrated into the densely used environment of Stuttgart Airport and Messe Stuttgart. This structure is complemented by the underground airport/trade fair station, which will serve as an important future transport hub for rail travelers. The new airport tunnel passes under both the busy A8 highway and the densely used trade fair and airport grounds - an environment in which precision, ground engineering expertise and comprehensive safety coordination had top priority.

Lot VE NBS East (Lot 2)

The Vergabelos VE NBS Ost extends the entire section by a central infrastructural component and combines modern railroad construction with comprehensive road construction measures. Along the A8 freeway, a 2.3-kilometre-long above-ground railroad line parallel to the freeway is being built, forming an important section of the new high-speed link. In addition to this, the Plieningen southern bypass is being implemented, which includes the relocation of the L 1204 state road and the reorganization of the junctions to the L 1192 state road and the B 312 federal road. As part of this reorganization of the traffic area, several road and railroad overpasses will be built, which will significantly increase the efficiency of the mobility hub. In addition, new road troughs will be built for the access and exit roads of the A8 highway in order to efficiently bundle and safely guide traffic flows. Water management measures will also play an important role: the construction of rainwater retention basins, additional hydraulic structures and extensive noise protection systems will contribute to the sustainable and safe operation of the new infrastructure. In addition, numerous service roads, cycle paths and footpaths are being adapted or completely rebuilt in order to permanently improve accessibility in the surrounding area and support multimodal transport solutions.

The project sets standards in the field of sophisticated tunnel construction and shows how interdisciplinary teams, innovative methods and sustainable construction can lead to a pioneering result - an outstanding example of how modern engineering technology can create efficient mobility corridors in the long term. The interdisciplinary collaboration between civil engineering, geotechnics, surveying and safety coordination was crucial in this project. The new airport tunnel is much more than just a traffic route. It creates additional capacity, improves the airport's connection to the regional and national transport network and helps to reduce congestion and emissions. Optimized traffic flows reduce CO₂ emissions and travel times - a significant contribution to sustainable mobility. Durable materials and resource-saving processes were used for the construction, which minimize subsequent maintenance costs. In addition, lighting systems with LED technology, energy-efficient ventilation concepts and state-of-the-art safety and control technology were integrated. The airport tunnel is an efficient, durable and safe piece of infrastructure that will strengthen the region's mobility in the long term.
