The NSW coalition has promised to contain big infrastructure project blowouts if it wins government on Saturday.
NSW Opposition Leader Barry O'Farrell on Wednesday kicked off his Real Change for NSW bus tour with his first stop in Drummoyne, in Sydney's inner-west.
Mr O'Farrell used the backdrop of the Iron Cove Bridge duplication to highlight what he says is one of Labor's failings when delivering big projects to NSW residents.
He said the project's cost had blown out from $100 million to $175 million and its completion had been delayed by two years.
Mr O'Farrell also said the new bridge had only shifted the problem it was intended to address.

"It simply moved a traffic jam a few minutes down the road," he told reporters.
"A patch-up job from a state government that never addressed the fundamental problems."
Mr O'Farrell stopped short of promising that all infrastructure projects under a coalition government would be delivered on time and within budget.
"We'll be working overtime to make sure it doesn't happen," he said.
"We've committed ourselves that cabinet will be briefed monthly on major projects like this."
Opposition transport spokesperson Gladys Berejiklian said Labor had failed to focus on improving public transport to get more vehicles off the road.
"This electorate, like so many across the state, demonstrates how wrong the Labor Party's got it in the last 16 years when it comes to public transport," Ms Berejiklian told reporters.
The coalition's bus tour of NSW kicked off on Wednesday with four buses loaded with coalition MPs heading to every electorate in NSW to campaign until the election on Saturday.
Mr O'Farrell's bus will focus on the Sydney area.
His wife Rosemary joined him on the bus as it headed to its next stop in Burwood.
