The bridges designed by Richard Horden for Expo 2000 are made entirely of aluminium. They are characterised by their lightness, slenderness and – thanks to prefabrication – ease of assembly. The bridges all have a very differentiated hollow box cross-section in sheet metal construction with integrated ribs and stringers.
Trough-shaped Cross-Section – Particularly High Load-Bearing Capacity
In the railing area, the box girder is partially raised, creating a trough-shaped cross-section with a particularly high load-bearing capacity. The construction principle of the bridges is closely related to the construction principles of aircraft construction and car body technology. The design of the form takes into account the course of forces as well as an elegant integration into the surroundings. A carefully placed glossy line in the elevation surface of the bridge reinforces the impression of special lightness.
