PROJECT DESCRIPTION

The Perry Bridge is the final link in the chain of the 70km Te Awa River Ride Walk and Cycleway. A visually stunning, innovative network arch, the bridge is very long and slender, spanning 130m at just 3m in width. The bridge was installed using a unique cable launch method. The efficiency of this form of structure kept its costs within a practical budget, while also presenting the local district council and Te Awa the opportunity to create a visually compelling focal point to help attract people to the Cycleway.

Judge's comment:

The Perry Bridge in Waikato, New Zealand, helped to create a beautiful focal point that attracts people to the new Cycleway. This extremely elegant footbridge required careful design to deal with pedestrian vibrations, particularly as its supporting arch is very long and slender. An additional challenge was designing to seismic loading. The judges were particularly impressed by the construction methodology; it was launched using cables in just two hours. It demonstrates excellent value to the client in terms of its cost, reduced materials compared to a conventional truss, and its quick construction. The local community has been involved throughout, with artwork designed by local students, and their celebrations on its opening.
