You've managed to sustain my hit rate over the three weeks I've said nothing on anything else. There must be around half a dozen classrooms doing this! (I have an invisible counter)
Just search Transmission Gully on my blog, you'll find tons that isn't pro-Gully, that isn't pro-rail, but is pro-efficiency.
Remember, it is a long way towards being built. The Transit NZ Board has to decide whether to support it as the long-term option, and then funding has to be found, and the project needs about two years of detailed investigation (easily worth $3-$5 million) first. Transmission Gully wont be a problem for this government, it will be a problem for the next one - it wont be affordable then either.
