The Rheinkniebrücke in Düsseldorf is a cable-stayed bridge over the Rhine from 1969, which connects Friedrichstadt and Unterbilk in the 3rd district (on the right bank of the Rhine) with Oberkassel in the 4th district (on the left bank of the Rhine). It leads on the left bank of the Rhine into the Rheinalleetunnel, which creates a connection to the federal highway 7, which merges into the A 52, from which it goes on to the motorway to Aachen and Belgium. On the right bank of the Rhine it has a direct connection to the Rhine bank tunnel and leads straight to the southern city center. Together with the North Rhine-Westphalian state parliament, the Stadttor high-rise office building and the Rheinturm, the Rheinkniebrücke dominates the cityscape at the Rhine knee, the section of a river bend in the Rhine that runs in the shape of a knee. The government district of North Rhine-Westphalia extends on both sides of the foot of the bridge on the right bank of the Rhine.
The name Rheinkniebrücke is derived from the location of the bridge on a tight curve in the Rhine. Seen from the air, this section of the Rhine looks like a human knee.
