Work to replace a 78-year-old bridge on the Burnett Highway near Eidsvold began last week.
Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development Michael McCormack said the timber Lochaber Creek Bridge will be demolished to make way for a stronger and wider concrete structure.
"This is a $9.7million project, funded equally by the federal and state governments," Mr McCormack said.
"The existing bridge has narrow traffic lanes and requires regular maintenance to keep it in safe, useable condition. The new bridge will be safer, more reliable and better suited to the vehicles types and traffic volumes using it."
Queensland's Transport and Main Roads Minister Mark Bailey said the project, jointly funded by the Bridges Renewal Program, was a win for local motorists and freight operators.
"The Lochaber Creek Bridge project is a great example of what can be achieved when two levels of government work in partnership for the benefit of local communities," Mr Bailey said.
"Not only will the project support up to 32 jobs in the region, it will also improve safety and connectivity for the freight operators who keep Queensland moving.
"Speed restrictions have been in place on the Burnett Highway at Lochaber Creek Bridge since July to reduce the impact of heavy vehicles on the structure but will return to 100km/h when the new bridge opens to traffic."
Mr Bailey said during construction a temporary side-track diversion would be in place to keep the Burnett Highway moving.
"I want to thank the community and freight operators in advance for their patience and cooperation while this crucial bridge-building project is underway," Mr Bailey said.
"For everybody's safety, please slow down and follow the directions of work site crews."
Doval Constructions will deliver the new Lochaber Creek Bridge with the worksite operational from 6am to 6pm, Monday to Saturday and expects the new bridge to open in mid-2019.
Federal Member for Flynn Ken O'Dowd said the works will also reduce the need for ongoing maintenance.
"As part of the project, we will realign and upgrade the Malmoe Road intersection, just north of the bridge, to provide better visibility when accessing the highway," Mr O'Dowd said.
"We will also provide wider shoulders, so motorists can safely pass turning vehicles."
