Thresher Associates worked with Beca on a transport master planning project to develop an overall concept scheme which integrated the new Kopu Bridge into the surrounding landscape. The existing one way Kopu Bridge is to be retired to a footbridge with the new bridge set to replace it. The existing road will be re-aligned to accommodate the replacement two way bridge. The project involved developing a landscape concept, planting scheme and plans, sections and construction drawings for the roundabout and either side of the re-aligned road.
For motorists using the new Kopu Bridge, interaction with the site is a visual experience. The centre of the roundabout has been designed with low native vegetation for traffic visibility. To provide a more scenic and experiential journey for motorists theme planting was used along either side of the road. This part of the themed highway represents the kaleidoscope of cultures that have come to New Zealand. It is interpreted by a tapestry of planting with strong colours and contrast to represent the weaving of cultures.
