Project info

This section of the Warrego Highway between Oakey and Dalby has been the scene of numerous accidents involving overtaking manoeuvres. A high proportion of heavy vehicles (in excess of 26% with 37% of them being Type 1 road trains and B-doubles) use this section of the highway. There is also increasing morning and evening commuter traffic between Toowoomba and the Surat Basin. 

The department has considered various options to improve road safety with the ultimate goal of providing a four-lane divided road between Toowoomba and Dalby in the future. 

This 47.2km section has six existing overtaking lanes, three in each direction. The addition of eight overtaking lanes will take the average spacing of 11km between overtaking lanes to an average spacing of 5km between overtaking lanes. The overtaking lanes are located at:

  • Between Devon Park Road and Cockburn Road intersections
  • Between Malu Road and Bowenville, 2.5km west of the existing overtaking lanes at Malu
  • 5.3km west of the existing overtaking lanes at Auchmah
  • Between Griffiths Road and Blaxland South Road.
