Motorists can return to using Bulli Pass at night following six months of extensive work to repair three major landslip sites on the mountain.

As part of a natural disaster repair program, work is now complete on the landslip sites on the steepest section of Bulli Pass from the M1 to the hairpin bend.

Critical repair work involved installing long steel rods, called soil nails, to add strength to the slope and then applying a layer of spray-on concrete, known as shotcrete, to prevent further erosion.

This included installing 1740 linear metres of soil nails, 950 square metres of reinforced mesh and shotcrete, 370 metres of new horizontal drains drilled into the slope, 70 metres of new catch drains, 28 cubic metres of reinforced concrete beam and 80 metres of new guardrail.

Crews used long-reach excavators, elevated work platforms, concrete boom pumps and even operated in abseiling harnesses to access the landslip sites, which were up to 10 metres below the road.

The cost of the damage at the three landslip sites was $5 million and was a result of record-breaking rainfall in 2022. The repairs have been funded under the Commonwealth-state Disaster Recovery Funding Arrangements (DRFA).

Work is progressing at one other landslip site about one kilometre below the hairpin bend.

This site is about 50 per cent complete and the single lane closure will be in place until the remaining work is carried out.

A small number of night closures of Bulli Pass will also be needed to resurface sections of the road pavement and add new line-marking. The community will be informed of these closures in advance.

Quotes attributable to Maryanne Stuart MP, Member for Heathcote:

“We all saw the devastating impact of severe weather in 2022, which saw landslips across Bulli Pass.

“I want to thank the community for their patience while this significant and complex repair work was carried out, and it’s great to see Bulli Pass reopen to 24-hour access.

“I thank the Roads Maintenance Teams for all their hard work, especially when working at night, whilst most of us are asleep.”

“While there is still more work to be done, this is a huge milestone and means motorists can safely access Bulli Pass at night again.”
