Major structural alterations to the city Reconstruction work after the Second World War continued until the late seventies. Traces of destruction remained evident for a long time in Duesseldorf. Some roads had obvious "gaps", many of them disguised by billboards.
Major urban development measures, such as the aforementioned Berliner Allee, resulted in the extensive conversion and redesign of traffic intersections. The traditionally most important traffic intersection was the square outside the central station. It constituted an interface between the national rail system and the public transport system.
At the end of the fifties, plans were elaborated to redesign the area outside the central station and the nearby Worringer Platz. The conversion work was finished in 1962.
In October 1962, Jan-Wellem-Platz, the biggest building project since the Rheinbahn’s foundation, officially opened. It was built on a former scene of destruction between Hofgarten Park and the western part of Schadowstrasse. Before its conversion, private traffic and public transport were highly concentrated in this inner city area.
