NSW Transport Minister Gladys Berejiklian has brushed aside reports of a $74 billion shortfall for the state’s new transport master plan.

Leaked cabinet documents show the cost of the plan is now $137 billion, which includes the $74 billion shortfall, News Ltd reported on Monday.

It said the document was a cost plan presentation for the masterplan marked “cabinet-in-confidence” and also tipped that road users face paying at least $22 billion in tolls over 20 years.

Ms Berejiklian said on Monday she had not seen the document and did not know what it was referring to.

“We’re a government that delivers what we announce,” she told Macquarie Radio.

“When we announced the Transport Master Plan last week, we backed it up, we demonstrated the projects’ funding that we have in the next three or four years.”

The document recommends deferring a second harbour crossing until at least 2023.
