Australian Tunnelling Society Mt Coot-Tha Quarry Industry Day
Australian Tunnelling Society Mt Coot-Tha Quarry Industry Day. Most of the attendees had not been inside the Mt Coot-Tha Quarry that sits virtually next door to the Brisbane CBD and Brisbane River.
The size and magnitude were surprising, however, the key takeaway for me was the latest role that it played with the 513m long conveyor tunnel that has imported all the tunnel spoil from the Cross River Rail Project to the quarry to eliminate approximately 110,000 truck movements off the Brisbane roads.
The tunnel portal has reached the end of its design life and has since been closed up.
