An example of a folding bridge is the Hörnbrücke (Hörn Bridge) in the city of Kiel in the German state of Schleswig-Holstein. When the bridge is down it spans 84 feet across the Kiel Fjord, known as the Hörn. The three-segment bascule bridge folds up into the shape of the capital letter N to allow for ship and boat traffic.
