Apologies, you are correct.
SKM and (former) RTA estimated the cost of M2 to F3 link at $4.75 billion - less than half what I said.
So around $600million per km
the SKM consultant estimates that the road will cut 'up to' 15 minutes from travel times.
So, probably a bargain - perhaps we just keep building more motorways. they seemed to have solved most of Sydney's transport issues to date
