Four-year motorway development almost ready to roll
Delays around Hillsborough Rd occurred because the ground was swampy and a significant amount of rubbish was uncovered during excavation, which surprised workers, says Mr McDonald.
Ground condition and heavy rain in 2006 also caused delays.
The Auckland Volcanic Cones Society worked with the agency to produce the bare-rock effect under the Dominion Rd bridge after finding solid basalt around Mt Roskill.
Christ the King School, on the corner of Richardson Rd and the new motorway, was also demolished and rebuilt less than 50 metres away to avoid noise disruption from the extension.
The agency has worked with Friends of Oakley Creek and Mr McDonald says around 250,000 native trees and shrubs have been planted throughout the construction. He is particularly proud of the cable-stay footbridges, which he says are an “engineer’s delight”.
Mr McDonald says projects of this scale are always several years in the making and then “all of a sudden everybody is at the right place at the right time and it happens”.
More than 2000 people were involved in the construction of the motorway at various times, with about 250 people working on it at any one time.
The area linking to Richardson Rd will open first and a ribbon cutting ceremony is planned.
