Waterview Tunnel opening day

Waterview Tunnel is a key piece of the Western Ring Route, a 48km motorway route through the west of Auckland, connecting Manukau, the city, West Auckland and the North Shore. The 2.4km Waterview Tunnel between Pt Chevalier and Mt Roskill opened today!, and cost $1.4b to build.
We all (7 of us) biked from Mt Albert to the eastern end of the tunnel today, walked through and back, and then biked home again. Apparently 20,000 people walked it today. So many people and hundreds of cars. A fascinating thing to do.
I'm now back in Christchurch - a very interesting weekend and fun to be with the family.
