AN aboriginal group frustrated at negotiations with Nexus and the Department of Transport and Main Roads over the Toowoomba Second Range Crossing is planning a protest which could halt works on the project.
The Western Wakka Wakka are preparing to protest at two sites which they say are culturally significant - and in danger of destruction.
A member of the group told The Chronicle this morning that negotiations about the sites had broken down.
"We're bringing in a mob to set up camp," he said.
"We're not letting them (destroy these sites)."
The Western Wakka Wakka man said bus loads of supporters would be brought in to the two sites from Toowoomba, Maryborough and Brisbane.
An 11th hour meeting will be held today between the parties at 10am.
If no resolution is found then the protest will begin.
The department has previously said independent archaeology studies had shown there was no evidence for a bora ring or station at either of the sites.
A spokesman also promised further studies before demolition works would begin in Charlton, and that appears to have been completed - also finding no evidence.
