The West Gate Tunnel doesn’t stack up and it should never have been approved.
Its economic benefits were overstated in the business case. Rather than $1.30, the project will probably return only $0.60 per dollar invested.
It doesn’t stack up financially either. Transurban needs $2.6 billion from the public purse, plus more toll revenue from CityLink, to make it work.
The Government’s assessment of the West Gate Tunnel contained significant errors in the transport modelling and the cost-benefit analysis that made the project seem a lot better than it was. It should never have been approved, and I predict that when it eventually opens it won’t deliver the claimed benefits.
