Transport for NSW says slope repairs are progressing well at Stanwell Park, so the road will be reopened at 7pm on Sunday August 9.
Regional Director Southern, Jo Parrott says recent heavy rains have had an impact on the site, but crews were able to continue working.
She says so far, more than 80 per cent of the soil nails required to stabilise the road have been installed, “Four sites have been completed,” she says, “and a 29 metre concrete retaining wall has been built at the highest risk site to stabilise and strengthen the slope.
“The remaining schedule includes completing work at six sites, revegetating slopes, installing mesh and shotcreting, with drilling at all sites expected to be completed soon.
“We thank the community for their patience with the road closure required for this work, which is essential for keeping the road safe and open to traffic in the long term.”
More than 3600 passenger trips have been made on the shuttle buses provided to help locals work through the closure.
Detours are still in place via Bulli Pass (Princes Highway) and the M1 Princes Motorway until Bald Hill reopens.
