Müngsten Bridge is the highest railway bridge in Germany. The bridge is 107 metres (351 ft) high and spans the valley of the river Wupper, connecting the cities of Remscheid and Solingen. This stretch is part of the Wuppertal-Oberbarmen–Solingen railway. It is used exclusively by the Rhine-Ruhr S-Bahn line S 7. On 1 April 2013, the Müngsten Bridge was closed for extensive renovation work: it reopened on 27 July 2015, but a further lengthy closure for a comprehensive corrosion treatment is planned for 2018.
