The speech notes that it is 30 years since the then Greiner government stopped work on the Maldon Dombarton link.
This was when the contract to build the 4 km Avon tunnel was cancelled. The contract price was just over $20 million, and some $10 million was paid for preliminary work and compensation for not finishing the job.
A very expensive mistake, as it will now cost over $100 million to build this tunnel.
