TOOWOOMBA SECOND RANGE CROSSING
Toowoomba Second Range Crossing is a 41 km grade separated, dual carriageway bypass and partial ring road constructed to the north and west of Toowoomba, Queensland
The $1.6billion Toowoomba Second Range Crossing is a 41km heavy vehicle route jointly funded by the Australian and Queensland Governments. The route was designed to increase freight efficiency and significantly improve driver safety and community amenity by removing heavy vehicles from Toowoomba’s CBD.

This Scope of Works for the provision of new cut batter protection included:
Slope Protection in the form of erosion control matting requiring with over 20,000 linear metres of GRP ground anchors and 84,000m2 of GREENAX matting.
Slope Stabilisation incorporating 2,000m of double corrosion protection (DCP) ground anchors 2,000m3 of shotcrete, 1,500m of sub horizontal drainage.
Ancillary Support including berm reinstatement, dentition and crack sealing.
These works were completed using a combination of tracked production anchoring and mini piling drills, rotary and percussive drill masts mounted on excavators and rope access techniques where drive on access was restricted due to earth work constraints.
