The bridge is made from about 81,000 cubic metres of concrete and 12,700 tonnes of steel. Each day, about 30,000 cars pass over the bridge. It took 4 years to build it, its total cost being 160 Million DM.

The bridge was designed by Hans Wittfoht and Egon Jux.

Since it's opening the bridge has only twice been open to pedestrians, on the opening day 1974 and on its 30th birthday in 2004. The magnificent view over the city of Hamburg is however not completely limited to the drivers of cars and trucks. 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.
