Sections of the Landsborough Highway north of Longreach have begun to reopen as floodwaters recede and road surfaces are able to be inspected.
Police advised on Thursday morning that the section of the highway between Longreach and Winton was open with caution required near Mills Creek and Jessamine Creek about 5km south of Winton.
Traffic is restricted to one lane, controlled by traffic signals, due to shoulder damage on the road.
The section between Winton and Kynuna was expected to reopen later on Thursday, once repair and clean-up work was completed near Wokingham Creek.
The Landsborough Highway remains cut at McKinlay, but shire mayor, Belinda Murphy, hoped it would be open for traffic either late on Thursday afternoon or Friday morning.
Updates are provided on the Queensland Traffic page, which shows Plumtree Creek north of McKinlay still has water over the road.
On the Flinders Highway, Cr Murphy said the road between Julia Creek and Cloncurry was definitely still shut until at least Friday.
She said floodwater needed to subside enough that inspections of road damage were able to be carried out and repairs made.
Some trucks were let through with a police escort in order to resupply Mount Isa and Cloncurry.
For the traffic that is able to move, restrictions remain in place for over mass and over dimension loads until at least Monday, March 12, subject to ongoing road conditions.
