Works worth $1.5 million are due to start at the Pacific Motorway (M1) Exit 49 northbound off-ramp at Pimpama.
Transport and Main Roads Minister Mark Bailey said construction was imminent on the short-term project.
“These works will create more capacity at the northbound off-ramp and also involve the installation of roundabout metering at the Rifle Range Road and Yawalpah Road roundabouts,” Mr Bailey said.
“Roundabout metering technology will control the flow of traffic at the roundabouts, and reduce the need for motorists to queue on the M1 shoulder, which we often see at peak hour.
“This project is in addition to the half a million dollars the Palaszczuk Government has invested for planning to complete major upgrades at this exit and exit 45 at Ormeau.
“As well, business cases are now underway for Exit 38 Yatala North and Exit 41 Yatala South with $4.2 million committed, while as per our 2017 election promise, we are investing $25 million to upgrade the Oxenford Interchange.”
Mr Bailey said the newly announced works at Exit 49 would begin later this month and be completed by the end of the year.
“This project is just the start of a broader works underway to ensure traffic continues to flow through the area and the safety of motorists is improved,” he said.
More than $2 billion worth of upgrades have either commenced or are now in the pipeline for the M1.
