Seven culverts on the Flinders Highway between Charters Towers and Richmond have now completed upgrade.
The works were part of the $25 million Northern Australia Roads Program and funded by the Australian and Queensland governments under an 80:20 split.
Transport and Main Roads North Queensland Regional Director, Sanjay Ram, said the upgrades were helping to improve the reliability and capacity of the Flinders Highway.
“It is important we sustain and continue to improve the reliability of the Flinders Highway for both the state and federal economy,” Mr Ram said.
“The link between Townsville and Mount Isa is essential to the movement of people and freight to support the North’s economic development.
“The Flinders Highway is used by key industries including the mining and agriculture sectors, playing a crucial role that strengthens trade in area.
“These culvert upgrades also benefited the construction industry, with 65 direct jobs being supported over the life of this project.”
The scope of works for this project included replacing culverts, that were past their design life and were showing signs of structural fatigue.
