Gareth Morgan and Geoff Simmons: An urgent review of roading policy is needed to prevent Wellington going up a blind alley: http://www.stuff.co.nz/dominion-post/comment/columnists/9306413/Headed-in-the-wrong-direction
It takes a scathing look at the inadequate or nonexistent analysis underlying the Government’s Roads of National Significance plans for the Wellington region. It does list the proposed Basin flyover as one that has a mooted Benefit-Cost Ratio of greater than 1, but a little more digging would have revealed that the Basin BCR is only greater than 1 because NZTA rejigged their calculations to make it so.
When even such mainstream figures as Gareth Morgan are calling for a rethink, the Government and the relevant local authorities ought to see that they have a real problem with roading policy.
