A major traffic switch is taking place next Wednesday December 20th on the Warrego Highway to allow work to continue on the Toowoomba to Oakey Duplication Stage 2 project.
Motorists are being advised well in advance of the switch west of Charlton.
The works will affect vehicles on the highway for around 5 kilometers between Leeson Road and Kingsthorpe Haden Road.
Traffic will be diverted on the new alignment to allow work to continue on the project.
Drivers are being warned that there will be reduced speed limits in place and are being asked to drive with caution.
Total cost of the duplication project is more than $160 million.
