Reconstruction works have been completed on the Landsborough Highway in the state's west between Winton and Cloncurry.
The Transport and Main Roads Department says the $41 million project has taken 16 months to complete.
Spokesman Peter Trim says a 300 kilometre section of the highway was damaged during the 2010/'11 floods.
"To put you in the picture, there was about 2.4 million tonnes of bitumen or several thousand tonnes of gravel and a number of locals were employed on that road with support for 20 or 30 local business here both here in the northern end of that section and around Winton," he said.
