RMA Soils has provided the Toowoomba Regional Council and TMR with a landslide survey and mapping.

The results have been used to assist in the design of cuttings and embankments for the Toowoomba Second Range Crossing alignment. Bulk earthworks on the central section of the crossing in now underway with excavation of large quantities of soil and rock, followed by the start of construction of the New England Highway realignment and twin arch bridges on the highway over the TSRC where it cuts through the Toowoomba Range. Regular updates on progress are provided care of the TMR website.
