17 rural bridges to be upgraded as part of $300m scheme

A MAJOR upgrade of 17 rural bridges across Queensland is being done at a cost of $300 million to improve infrastructure, with projects in Central Queensland, Toowoomba, Warwick, Maryborough and Caboolture.

The most expensive upgrade will be the $70 million needed to upgrade four bridges on the Peak Downs Highway between Mackay and the coal mining precincts of the Bowen Basin.

The Australian and Queensland governments are going 50-50 on funding.

Four timber bridges will be replaced with concrete structures.

Other projects are also being part-funded by local governments.

Deputy Prime Minister Warren Truss said the changes would improve safety and allow freight to travel more easily through our regions.

"By upgrading these bridges, for example, by replacing one-lane timber bridges with two-lane concrete bridges, residents will enjoy better and more reliable road access," he said.

Queensland Main Roads minister Mark Bailey said the upgrade to the Peak Downs Highway would allow freight to move more efficiently.

The highway is a key route for transporting mining machinery, parts and vehicles between towns and coal mines.
