Mechanical Innovations Developed for the Lille Langebro Swing Bridge, Copenhagen

The Lille Langebro (Little Langebro) pedestrian and cycle swing bridge opened to the public in August 2019. The bridge provides a quay-level crossing of the harbour for pedestrians and cyclists and was the outcome of an international design competition. In order to enable the passage of marine craft along the harbour the central sections of the bridge rotate. This paper gives a brief overview of the operating equipment associated with the movement of the two rotating spans before a more detailed discussion on the innovative moment connection developed to secure the joint between the two moving spans when in the bridge closed position.
