The Government today announced plans to build an alternative Waitemata Harbour crossing, alongside further upgrades to Auckland's North Shore.

The alternative crossing includes two three-lane road tunnels and a 21 kilometre Light Rail tunnel between Albany and the CBD.

Transport Minister David Parker is confident the second Waitemata Harbour crossing will be built within a clear timeframe.

"We've had extra lines being put in on the railway, we've had the City Rail Link built. Those are political insults, rather than fact-based."
