    “Thanks to this innovative and creative engineering performance the usability of existing buildings is prolonged sustainably“. This was the reasoning for example, of the jury for the German Viaduct Construction Award (Deutscher Brückenbaupreis) 2016, which was awarded to the engineering office Leonhardt, Andrä and Partner for the planning, as well as the engineers of LEONHARD WEISS for the execution. The large-scale project “Retrofitting of the Kochertal Viaduct“ on the Autobahn A6 near Geislingen proves, that and in which manner German engineering from the 1970-ies can be further developed in an innovative way. The construction engineers developed unused potentials of the viaduct structure in detailed analyses. By doing this, the load bearing capacity of the existing structure could be improved by means of comparably minor interventions to exceed its original state. Germany’s highest viaduct is much stronger than before this measures were taken and it is now fit for the congestion of the future.
