Hering employees erected noise barriers on both sides of the railway bridge that runs over Roermonder Road (Aachen). The noise barriers were mounted from the track on behalf of B + H GmbH in Ettlingen and DB Netz AG Cologne as the builder. The work was part of the complete new construction of the bridge. 41 steel posts, 80 m² of concrete bases, 250 m² of aluminium protection elements and 110 m² acrylic glass elements were installed.
