Baird spruiks $20b cash splash in NSW TWO new Sydney Harbour tunnels have been proposed as part of election-bound Premier Mike Baird's $20 billion splurge on infrastructure in NSW. THE money is subject to the sale of 49 per cent of the state's electricity distribution network - commonly referred to as the poles and wires. NSW is due to go to the polls on March 28. A rail crossing under the harbour to link up the new North West and South West lines has been mooted, but the government has also proposed a western harbour road tunnel from Rozelle rail yards in the inner west to link with the Gore Hill or Warringah freeway in Sydney's north. The road tunnel is designed to allow up to 50,000 vehicles to bypass Sydney's city centre and ease congestion. Construction is not expected to start until after 2020. The government said $1.1 billion would be spent on West Connex northern and southern extensions and the western harbour tunnel. "It will provide people travelling form western Sydney via the M4 with a direct link to employment centres in Sydney's north and northwest," Roads Minister Duncan Gay said. The spending package includes $7 billion for the Sydney Rapid Transit, which will help link the North West and South West rail lines. The government also plans on spending $4.1 billion on regional transport, a decision Deputy Premier Troy Grant described as a shot in the arm for country NSW. About $2 billion has been set aside for public schools and hospitals. The rest of the $20 billion, however, is yet to be directed towards specific projects. Mr Baird said more detail would be released before the election. He denied he was promising too much. "I'm not going to sit here and promise something that we can't deliver," he said. Everything in this plan is non-negotiable. They will be delivered. We have a plan, we have the funding, we will deliver. But if we don't win the election, it's over. Opposition Leader John Robertson said the government's plan was full of hollow promises and short on detail. "People don't believe a document like this," he said. When you've got projects in there like the western harbour crossing - where there is a fraction of the money put on the table - no-one believes it. When you've got the announcement of a second harbour crossing and no business case will be completed for two years, it just doesn't pass the believability test.
