Lehnitz Bridge

The Berlin-Stettin shipping route (later the Hohenzollern Canal, now the Oder-Havel Waterway) was built by 1912 to provide a direct link between the metropolis of Berlin and the Baltic Sea port of Stettin. The old wooden bridge had to make way for the new "Lehnitzer Bridge". With its elegantly curved steel arches, this bridge met the technical requirements of the time. It was blown up by an SS demolition squad in 1945.
The new bridge was only inaugurated shortly before Christmas 1957, after almost two years of construction. The construction work was carried out by the steel construction company "Beuchelt & Co. Könnern (Saale)", known for rebuilding many destroyed bridges in the former GDR. During the first construction phase, the old bridge foundations were demolished and the new substructure was built from reinforced concrete. Initially, only two double-T girders spanned the canal. The actual steel construction of the superstructure was riveted on the Lehnitz side of the river and then pulled to the Oranienburg side.
