The most recent structure is the 50-metre- long HERING noise barrier on the Geratal bridge. The structure spans the ‘Wilde Gera’, an 85-kilometre-long tributary to the River Unstrut.
The installation work presented a particular challenge in that it was necessary to carry it out from the front: it was only possible to set the posts after the scaffolding had been suspended in place. The aluminium elements were then lifted into position by a road-rail excavator once the scaffolding had been removed.
Every stage of the work was carried out in consultation with and under the supervision of the nature-conservation authorities as this section of land is part of a water-conservation area.
