The Department of Transport and Main Roads says roadworks underway in the Northern Flinders will shore up the north-west Queensland region's main routes ahead of the wet season.
Flood damage works are underway on the Gulf and Kennedy developmental roads, funded under the Natural Disaster Relief and Recovery Arrangements.
Department spokesman Tony Potter says the region's roads are periodically washed away during the wet but new guidelines mean they will stand up better over time.
"The pavements have been designed for about a 10-year traffic life," he said.
"Previously you could only restore works to what its previous standard was, so that if the road was getting saturated and trucks were going through it in the wet season, it would happen every wet season.
"Now we're able to actually take into account that and improve the pavements so that we don't get the same damage again every year."
Mr Potter says crews are working on roads damaged by flooding and wet season downpours up to three years ago.
"Some of it goes back to 2010. As you know the whole of the area got hit both in 2010, 2011 and again in 2012," he said.
"These sites are under the Queensland Reconstruction Authority program.
"If a piece of road was damaged in 2010 and we weren't able to get it repaired by 2011 and further works got damaged, we've incorporated all of those into a single contract package."
