Tunnel vision

The construction of the biggest and most complex roading scheme in New Zealand has provided a fantastical spectacle these past couple of years. Waterview is the central hive, with its subterranean pit and its underground tunnels connecting Auckland's northwestern and southwestern motorways; above ground, the Te Atatu causeway is being widened and lifted above the tidal mudflats, and huge concrete pillars are marching in a fascinating matrix towards Pt Chevalier.
