This footbridge is the most visible built element in the $220m SH18 Hobsonville Deviation / SH16 Brigham Creek Extension motorway project which connects the Northwestern motorway from Westgate to the Upper Harbour Crossing.
The arts brief developed for the project acknowledged the proximity of the bridge to Auckland’s early brick and pipe industries, located in this part of the upper Waitemata harbour, and a route linking the remarkable heritage Clark House, slated as a future ceramics museum.
Reconnecting the offset ends of Clarks Lane severed by the new motorway, the urban design framework envisaged the bridge providing both a viewing point and a landmark/beacon along this rare straight stretch of motorway.
A symmetrical cablestayed design solution was developed, incorporating a generous 2m wide deck to encourage pedestrian and cycle use.
The steel box beam structure was fabricated and painted offsite. The steelwork is painted yellow to reflect the ‘Clay carpet’ arts theme, set off by polished stainless steel handrails, zinc/aluminium coated mesh barrier infill and the black HDPE-encased cables.
Purpose made ceramic tiles from commissioned artists provide a border to the exposed aggregate deck finish and inventively continue the themes of movement and of local history.
The bridge is enhanced at night by linear lighting under the box beam for motorists and pylon-mounted lighting and yellow buttons set along the deck centreline for pedestrians.
Overall, this bridge provides a visual centre for the SH18 ‘Gallery Route’ which is economical in both structure and cost.
