Industriestraße, Stuttgart-Vaihingen
Stuttgart, Germany /
On behalf of the Stuttgart Civil Engineering Office, A. WAGGERSHAUSER STRASSENBAU GmbH + Co. KG, a subsidiary of PORR, is redesigning around 400 metres of Stuttgart's Industriestraße. The construction project in the southwestern district of Vaihingen will be carried out in four phases. Work on the ‘Am Wallgraben’ roundabout began in mid-January 2024 and will continue in sections until the Ruppmannstraße intersection. Single-lane traffic will be maintained throughout the entire construction project in order to minimise disruption. The work in the vicinity of high-pressure gas lines and underground high-voltage lines (110 KV) poses a particular challenge. This work requires the utmost care and special safety precautions.
Industriestraße is one of the vital traffic arteries and the centrepiece of the Stuttgart planning concept WERK-QUARTIER. This envisages adapting the Vaihingen/Möhringen industrial area to current developments with large-scale new office developments. This development also includes the redesign for future mobility and a more attractive environment.
Improving the experience for all road users
The new 12-metre-wide carriageway is being built using the asphalt construction method. This involves a full upgrade with a thickness of 60 cm, as well as soil replacement below the subgrade. To ensure the necessary stability for the high traffic volume, a 30-cm-thick layer of coarse gravel is being laid (load class Bk 32). The carriageway will have 2-metre-wide cycle lanes on both sides.

In addition, 3-metre-wide footpaths with porous concrete paving will be laid on both sides to ensure good drainage of rainwater. To further enhance the quality of the area, green spaces with trees will be planted on the central islands. The plantings will be carried out using special plant substrates manufactured by A. Waggershauser.
In addition, the street lighting will be renewed and the bus stops will be redesigned in concrete construction with special bus curbs that allow barrier-free entry and exit. Barrier-free and blind-friendly pedestrian crossings are intended to improve safety and accessibility for all road users.
Thanks to efficient construction planning and the high level of expertise of all those involved, the project was completed within the planned time frame. The construction method used guarantees a high level of road stability, which can withstand heavy traffic. The building materials used, as well as the recycling of the removed concrete and asphalt residues in the in-house building materials recycling plant in Kirchheim (BWV), significantly support environmental friendliness and sustainability.
What ultimately counts in the construction business is successfully completed projects. PORR has many of these.
