The Kronprinzen Bridge is a road bridge over the River Spree in the city of Berlin. The original bridge was built between 1877 and 1889 and was demolished in 1972 to prevent refugees flows from the East Berlin to the West. The bridge links the Berlin quarters of Mitte and Tiergarten with the parliamentary quarter within the borough of Bezirk Mitte.
The New Bridge
The Kronprinzen Bridge in Berlin was a design submission for an invited competition held in 1991, organized by the Senatsverwaltung fur Bau und Wohnungswesen. The bridge was partially financed by the European Community and represents a symbolic gesture of the German reunification. The primary structural system is a steel-stiffened arch reinforced by cross ribs, which support the metal road deck. These components are thus engaged as the top and bottom chords of Veerendel truss, with the resulting reduction in both the weight and deflection of the span permitting a shallower than normal arch.
