Green Light for Wehrhahn Line in Düsseldorf

Two milestones of the Wehrhahn Line have been completed on schedule. The construction projects of the two stops, Graf-Adolf-Platz and Kirchplatz, have now been handed over to the general contractor. The BBM Group that was responsible for the construction completed the contract on time and by delivering the quality characteristics that are typical for the company: outstanding results, maximum safety standards and reliability in all aspects. BBM experts had assumed responsibility for the entire shell construction and other carcassing work, a large part of which involved water-impermeable concrete, on a length of 125 meters, respectively.

Düsseldorf continues to pick up momentum, with new dimensions of urban and transportation planning opening up at the city’s major traffic hubs. It goes without saying that the BBM team’s experts are in exactly the right place here, bringing practically unique knowledge in road and tunnel construction, particularly in the field of concrete work, to the challenge. Not least thanks to these fortes, the next large-scale BBM project in road and tunnel construction will soon be launched in Düsseldorf, as the company’s work will continue as part of the Kö-Bogen project.
