Project Description:

The 292 m long bridge crosses the Jiangxi River with a 152 m span spatial steel self-anchored arch. To avoid discontinuity between the curved road alignment the two lateral arch ribs follow the curved alignment of the road resulting in a warped geometry. Out-of-plane forces are controlled by lattice-roof-looking transverse bracings configurating an efficient spatial structure with an attractive design.

Judges Comments

This 152m tied-arch span has an unusual and distinctive basket-like form and supports a wide curved roadway with cantilevered footpaths on both sides. The complexities of the curved geometry required careful treatment in the design, and the arch form responds well to these challenges. The variable width tubular steel arches support a very shallow streamlined steel box deck with inclined hangers to form a very elegant overall ensemble.
