Revision Zero were engaged by NZ’s premier bridge fabricator to provide 3D modeling and structural steel detailing services for this landmark bridge.
The simplicity and elegance of the structure belie the hidden complexity of the design. The arch sections varied in cross section resulting in the side plates of the arch warping longitudinally.
Due to the both the bridge deck curving horizontally and the vertical curve of the arch, every post tensioned hanger had to be individually detailed. This also resulted in every bridge deck outrigger being unique.
