Bulli Pass will re-open from December 2, as the first stage of rock stabilisation works is completed three days ahead of schedule.
Roads and Maritime Services has spent the past seven weeks installing rock fall protection fencing along the roadway’s western edge.
Parliamentary Secretary for the Illawarra and South Coast Gareth Ward announced on Thursday the works would be finished ahead of the expected December 5 re-opening date.
The Pass will now re-open from 3pm on December 2.
“To have to reopen the road three times due to major crashes on Mount Ousley Road and still finish early is a great effort by Roads and Maritime and contractors involved,” he said.
There have been 447 rock anchors, 86 concrete pads and 86 posts installed beside the roadway since its closure.
About 600 metres of netting has been installed and more than 180 square metres of rock netting placed in gullies.
The road will be closed again in early 2017, to allow for the completion of the rock fall fence.
