This project was secured following a design competition by the NZ Transport Agency, the Christchurch City Council and Christchurch International Airport to develop a concept for a gateway to the City and the South Island beyond.
The design draws on the vertical power of the Southern Alps and the braided rivers, unique to the Canterbury Plains and provides a dramatic gateway for all travellers. The arching, fluid form captures the dynamism, excitement and essence of movement and travel.
By having the bridge’s structure obliquely cross SH1 in a clear arc, the bridge takes on a powerful presence from all points of view. The concept enables enhanced transport solutions for all modes of travel including cycles and pedestrians. Future proofing is afforded by the capability of light rail or dedicated bus lanes to be incorporated under the bridge at a later date.
Managing complexity
Construction for Memorial Bridge was complex; the 30 sections that comprise the two arches were fabricated in Napier, transported by road to the site, and erected over a four-month period. The BIM model was critical in both design and construction phases due to the complex geometry and tolerances required.
