The Liberal National Party has flagged a full review of southeast Queensland's freeway network if it wins the state election.
But the minority Labor government has accused the opposition of hypocrisy after the LNP repeatedly attacked it for conducting too many reviews.
Opposition Leader Tim Nicholls announced on Thursday that if elected he would commission a full review of the region's major arterial routes, in particular the Ipswich Motorway, M1, Centenary Highway and Bruce Highway.
"We will undertake a stocktake study of existing transport corridors to see if these are still viable as alternative routes," Mr Nicholls said.
However, the state government accuses Mr Nicholls of double standards after he repeatedly criticised it for conducting too many reviews.
In particular, he criticised the government's penchant for reviews during his budget reply speech in June, mentioning road infrastructure in particular.
"Whether it is building a highway or getting your driver's licence, the studies and reviews, the rules and regulations, the delays and red tape grow longer and thicker and nobody can tell you why," Mr Nicholls said.
Transport Minister Jackie Trad said Mr Nicholls and the LNP were playing catch-up on roads policy.
"On Tuesday, it was a petition with no funding for a grossly underestimated second M1," Ms Trad said in a statement.
"Through the SEQ Regional Plan we've already identified priorities for our future transport network and we've been getting on with building the infrastructure that our region needs. We don't need another plan, we need investment."
Mr Nicholls said his review would be different from those done by Labor.
"What we will be doing is putting in place the plan for congestion-busting roads that southeast Queensland needs," he said.
Mr Nicholls would not confirm whether his proposal for a second M1 would form part of the review, or if he would scrap Cross River Rail to help fund road infrastructure, saying only "watch this space".
The state election is due by May at the latest but is tipped to be called this year.
