A VITAL transport corridor linking the Atherton Tablelands to the coast will be upgraded following heavy rain in the region.
Large potholes have again opened up on the Palmerston Highway, which links the southern Tablelands to Innisfail.
Hill MP Shane Knuth said he had been lobbying for years for a permanent solution to repair the road, with potholes opening up after the smallest amount of rain.
Mr Knuth said he had been on Main Roads and the Ministers back since way before he inherited the southern section of the Palmeston Highway which took in the notorious section of road between Henrietta Creek and Gooligan Creek.
Mr Knuth said when the road was outside his electorate in 2017, he successfully secured $3 million for the Henrietta Creek section, which fell to pieces just four months after it was repaired.
He said after many complaints from motorists, he had again pointed out the seriousness of the problem.
While work will be undertaken to repair potholes on the Henrietta to Gooligan Creek section, Mr Knuth said a more permanent solution, like the road south of Gooligan Creek to Crawford's Lookout, was needed.
"While we are thankful that works are in the planning, now we want to see the same high standard of work undertaken like the Gooligan Creek to the Crawford's Lookout," Mr Knuth said.
"The last thing road users want to see are maintenance crews back out there four months later."
TMR district director Ross Hodgman said crews attended the area on June 1 to install warning signage.
"Due to the recent heavy rainfall our crews are attending to road maintenance in a number of areas," Mr Hodgman said.
"TMR will commence a rehabilitation project at Henrietta Creek in August 2020 with works expected to be complete by March 2021, weather permitting.
"We are also progressing a rehabilitation on the Palmerston Highway at Belvedere near Shaw's Hill."
Mr Hodgman said TMR was also investigating options to improve safety at the intersection of Palmerston Highway and Henderson Drive to allow safe B-Double turning movements at the intersection.
"We will continue to ensure regular maintenance works and emergent repairs are carried out in a timely manner with safety works taking priority," he said.
"Any further works on the Palmerston Highway will be prioritised against other important projects across the state."
