The Centenary Bridge upgrade is a step closer with the awarding of the construction contract.
Premier and Minister for the Olympics and Paralympics, and Member for Inala Annastacia Palaszczuk announced it's been awarded to Georgiou Group and BMD Constructions, as a joint venture.
"My government has a strong track record of backing Queensland workers, which is why I'm pleased this joint venture will support good local jobs in our community," the Premier said.
"This upgrade will see a new three lane Centenary Bridge built in Jindalee, as well an upgrade of the existing bridge, meaning you'll get home safer and sooner.
"More than 85,000 cars use this bridge daily, and that number will increase.
"This is an important step towards busting congestion through our growing region."
Speaker of the House of Representatives and Member for Oxley Milton Dick celebrated the announcement.
"The Centenary Motorway is the key link between Brisbane and the western suburbs," Mr Dick said.
"As our community continues to grow, we need transport to service the needs of commuters, holidaymakers, freight transport and business operators.
"I'm proud the Albanese Government is contributing to such a vital upgrade, making a difference in the lives of those who use the motorway."
State Member for Mount Ommaney Jess Pugh said it was a belated Christmas gift for the community.
"I have advocated for this project since I was elected, as I know how desperately our community wants shovels in the ground," Ms Pugh said.
"Previous tender submissions came in low, and another even promised to build two new bridges with the funding – both options had to be thoroughly explored to make sure we were getting the best value for taxpayers.
"After consideration, we saw that these tender submissions could not deliver on what was promised. I'm pleased we can now move forward with a reliable, Queensland based joint venture, with over 40 years experience.
"The project will double capacity across the river, as well as improve access to Amazon Place Park while preserving the much-loved Jindalee Skate Park.
"We know how important it is to include safe options for cyclists and footpath users, especially those who travel on two wheels, in a wheelchair, mobility device, or pushing a pram.
"Construction will start next year, and I know locals are just as excited as I am."
The upgrade includes a new 3-lane northbound bridge, rehabilitation of the existing bridge to 3 lanes southbound, and opportunities for improved active transport.
The Federal and Queensland Governments are jointly funding the $298.5 million project.
This extra capacity will mean greater efficiency and reduced travel-time between the CBD and western suburbs, between local destinations, and along the Centenary Motorway.
