Queensland Opposition Leader Deb Frecklington will outline a plan to bust congestion in southeast Queensland as part of her budget reply speech on Thursday.
The Liberal National Party would work with local councils to develop new major road corridors to ensure infrastructure keeps pace with population growth.
"Congestion in southeast Queensland is getting worse every day and Annastacia Palaszczuk and Labor have no long-term plans to fix congestion," Ms Frecklington said.
"Whether it's Gympie Rd in the north, the Centenary Motorway to the west, or Old Cleveland Road in the east, bottlenecks in Brisbane are severe and only getting worse."
The LNP has previously put forward a plan to duplicate a portion of the Pacific Motorway between Brisbane and the Gold Coast using existing parcels of land.
Labor Treasurer Jackie Trad's first budget contained a record $45.8 billion in infrastructure spending over the next four years, while state debt is set to rise to $83 billion over the same period.
Ms Frecklington is expected to criticise the debt level in her reply, however, will be under pressure to outline her own plan to pay down debt if the LNP took office.
She has previously deflected questions about the LNP's debt plan, pointing out the election isn't until 2020, with two more state budgets before then.
The LNP leader has also taken the government to task for its four new "luxury" taxes and its waste levy, which she's labelled a tax grab as it will pull in $1.3 billion over four years.
Ms Trad denied that, saying it was "entirely responsible and reasonable" that a portion of the money will go to government spending outside the waste and environmental sector.
