Moss Vale Road repair work

The first step towards restoring full traffic access on Moss Vale Road at Cambewarra Mountain is about to begin.

Work crews will be on site from Wednesday 17 May 2023 to begin repairs on the first of seven landslip sites on Cambewarra Mountain.

The work being done will stabilise a 190m2 landslip site above the road on the northern side of the mountain to make it safe for work to proceed on future sections requiring repair.

Record-breaking rainfall during 2022 caused widespread damage to sections of Moss Vale Road.

Rain gauges at Beaumont measured double the average annual rainfall in 2022, making it the wettest year on record. Both March and July last year saw particularly heavy rain, receiving four and six times the average rainfall totals respectively.

As a direct result of this rainfall, Transport for NSW added a total of 50 sites to its natural disaster recovery project register.

Since these natural disasters struck, Transport has made significant progress:

• completed repairs at 21 sites, with repairs in progress at another eight sites 
• carried out additional maintenance to clear landslip material from the road and stormwater drains 
• performed detailed investigations to assist with planning and designing repairs on more complex sites.

Our geotechnical team continue to monitor all active sites until repairs are completed.

Many of the landslip sites require complex repairs. 

Transport will engage specialist contractors to complete repairs that, depending on each site, could include:

• removing loose rocks, soil and trees
• stabilising and adding strength to the damaged slope
• upgrading stormwater drains
• repairing road surfaces and replacing guardrails.

Some factors are out of our control and can cause delays to our progress:

• Weather - heavy rain and storms could make working conditions unsafe.
• Workload – the statewide increase in demand for qualified contractors, equipment and resources could mean longer timeframes for repairs.
• Worksite – the steep site and narrow site could create some unexpected challenges.

Transport has developed a work plan for the first of seven sites on Cambewarra Mountain (site 28) to minimise the impacts on residents and traffic.

The main features of the plan are:

• working at night from 7pm to 5am
• working Sunday to Thursday nights
• providing traffic access through the site at the start of each hour, beginning at 8pm
• giving priority access to emergency services at all times.

Outside these work hours, the current single lane access will be in place.
