One section of Lawrence Hargrave Drive damaged by a landslip has been repaired while another stretch is expected to take nine more weeks to complete, according to Member for Heathcote Maryanne Stuart.
The three-month program of work on Lawrence Hargrave Drive at Scarborough – jointly funded by the Australian and NSW Government’s Disaster Recovery Funding Arrangements – cost about $2 million.
Normal traffic arrangements are now back in place after the road and pedestrian footpath were restored following flood damage in 2022 and early 2024.
More than 1200 tonnes of loose soil and rock were carefully excavated from the site in stages to reach a stable base before the road could be rebuilt. Forty-eight soil nails – eight-metre-long steel rods – were drilled under the width of the road to add strength to the slope.
Large foam blocks weighing about one per cent of the traditional fill were used as part of the road’s new base to significantly reduce pressure on the slope.
Forty-eight cubic metres of concrete was then sprayed across the slope below the road to help prevent future erosion.
The repair program was completed this week after final stages of work were carried out, including resurfacing a section of the road, installing guardrails and fencing, and removing concrete barriers.
Ms Stuart said the works were intended to make the road more resilient in the face of future disasters.
“I’d like to thank the community for its patience while this work was meticulously planned and carried out to ensure the safety of workers and motorists,” she said.
“This work has not only repaired landslip damage from severe weather in recent years, but it also improves the resilience of the road on the steep site for the future.
“Thanks also to the Transport for NSW crews and specialist contractors for carrying out repairs on the unstable slope close to the top of an 82-metre-high cliff face above the ocean.”
Work to repair landslip damage on another site on Lawrence Hargrave Drive, between Railway Crescent and Chellow Dene Avenue, began on 9 October.
Transport crews will excavate a 40-metre section of the slope beneath the road then rebuild the road base, resurface it and replace guardrails.
Work between 7am and 5pm Monday to Friday is expected to take about 10 weeks to complete, weather permitting.
