COMMENT: The inefficient use of the Waitemata Harbour for transport services, and successive governments' failure to face up to providing new and necessary infrastructure, namely twin tunnels under the harbour, to relieve the pressure on the Harbour Bridge, especially the ageing "clip-ons," is of growing concern.
During 1997-2010, I was on the North Shore City Council, Auckland Regional Growth Forum and Auckland Regional Transport Committee. I listened to many public submissions, presentations from NZTA, Government MPs and other officials about projected increases in bridge traffic, the likely end life of the "clip-ons" and the possible solutions. These included a second Harbour Bridge, or twin tunnels on the harbour bed.
Logic and cost indicated twin tunnels for public transport, including train travel.
The main variable was the question of the ingress/egress points, one of the advantages of the tunnel system being that these did not have to begin/end at the same points. Inflow and outflow could be better spread if that was desirable. This is State Highway 1 we're talking about, and tunnels were supported by NZTA, the Government, the ARC and councils.
The sticking points for the tunnels have always been about funding and timing. Governments have always fudged this by giving an "estimated" 20 years for completion. Meantime, other "needs" have been chosen as more immediate.
