it should be user funded : tolls and the SIGNIFICANT petrol tax increase to cover paying for it .
Of course, the true cost of driving is currently well obscured. Just like many other things are. My personal opinion is the costs of these should be properly borne by users - plenty of things people would stop doing if they had to actually pay their way.
If people want an unneccessary additional crossing, those people should pay for it. Particularly where it's shown to have negative benefits for everyone else.
If we need it done quickly , at low cost , we need to hand it over completely to a (say) chinese company & china based workers who can & do build these things very quickly.
Tell them just build it , no consents needed , no red tape, just do it .
Sounds like a disaster waiting to happen. I don't think for a minute our current process is at all efficient or effective, but I can't imagine free reign to an overseas entity is the way to fix that.
