A folding bridge is a type of moveable bridge engineered to fold. This allows ship traffic to pass through the waterway that the bridge spans.{{Cite web |last=McMahon |first=Mary |date=January 10, 2024 |title=What is a Folding Bridge? |url=https://www.allthescience.org/what-is-a-folding-bridge.htm |archive-url=https://web.archive.org/web/20221007213612/https://www.allthescience.org/what-is-a-folding-bridge.htm |archive-date=October 7, 2022 |access-date=January 15, 2024 |website=All the Science}}

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 {{convert|25.5|m|ft}} 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.{{Cite web |title=Hörnbrücke – Kiel, Germany - Atlas Obscura |url=https://www.atlasobscura.com/places/hornbrucke |archive-url=https://web.archive.org/web/20231208053720/https://www.atlasobscura.com/places/hornbrucke |archive-date=December 8, 2023 |access-date=January 16, 2024 |website=Atlas Obscura}}
