History

The bridge was designed by Hans Wittfoht and Egon Jux. It took 4 years to build it.

Since its opening the bridge has only twice been open to pedestrians, on the opening day 1974 and on its 30th birthday in 2004.

The bridge is on route of Hamburg's yearly UCI ProTour bicycle race Vattenfall Cyclassics. Quite a number of the amateurs participating in this race make a stop on top of the Köhlbrandbrücke.

Several people have committed suicide by jumping from the Köhlbrandbrücke.
