Paradise Gorge - Rock Removal in Columnar Dolerite

Joint meeting with Australian Geomechanics Society at 6pm Thursday 27th October. Presented by Clint Scott and Andrew Tyson.

In 2021 traffic could no longer flow between Hobart and Orford on the east coast along the Tasman Highway. Vehicles were diverted and all transport was rerouted. So what was all the fuss about? Rock columns in the dolerite bounding the gorge showed signs of becoming rock falls closing the road and endangering road users. The hazards were identified and were followed with remediation. This talk will outline the problem and solutions undertaken to mitigate the rock fall hazards on this important link between Hobart and the east coast.
