Nunteknik undertook the installation of joints which were produced by Maurer AG. Before closing traffic on the bridge, reinforcement works were done, deck and approaching viaducts were prepared for new joint installation. Then two traffic lane of the bridge was closed, old joint was dismantled and new joint was installed on place of it.
