Moss Vale Road repair work

We’ll be carrying out road resurfacing work on Moss Vale Road following recent landslip repairs to improve safety for motorists.

We’ll be working at night between 7pm and 5am from Sunday 14 to Thursday 18 September 2025, weather permitting. 

We’ll begin work from the top of hairpin near Cambewarra Lookout Road and continue down towards Barfield Road.

Slope stabilisation work will be carried out at two landslip sites on the eastern side of Cambewarra Mountain. 

Work includes clearing debris and vegetation, drilling long steels rods into the slope (known as soils nails), applying heavy-duty mesh or spraying concrete (known as shotcrete), improving drainage, and resurfacing and line marking the road.

We’ll be working at the first site, located one kilometre north of Barfield Road, from Sunday 6 July 2025 for around four weeks, weather permitting. Site set up will begin from 7pm Sunday 6 July, however our standard working days will be Monday to Friday.  

After work at the first site is complete, workers will move slightly south to the second site, around 750 metres north of Barfield Road. Work at this site will begin in early August and is expected to be completed by the end of the August, weather permitting.

Our working hours will be 6am to 6pm, Monday to Friday. On occasion, work outside of standard hours may be required, such as on Saturdays or at night. The community will be informed in advance if work outside of standard hours is required. 

Motorists using Moss Vale Road will experience short delays, with one lane closed to allow safe access to the landslip sites. Motorists are advised to allow an additional five minutes’ travel time. 

 _{Location of work area}

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

At Beaumont, rain gauges measured double the average annual rainfall in 2022, making it the wettest year on record. In both March and July the same year, the area experienced particularly heavy rain, receiving four and six times the average rainfall totals respectively.
Emergency work was carried out to repair significant damage at Barrengarry Mountain and re-open Moss Vale Road, which remained closed to all traffic for more than five months in 2022.

Escorted traffic access was necessary across Cambewarra Mountain for almost three months while emergency work was carried out to make the road safe. However, due to the extensive damage, the road was limited to single lane operations.

Transport for NSW added a total of 50 landslip sites on Moss Vale Road to its natural disaster recovery project register from the 2022 weather events.

Since then, we have completed major repairs at 37 landslip sites and carried out additional maintenance to keep the road and stormwater drains clear.

Many of the landslip sites require complex repairs and are often in hard-to-reach locations. While the work required at each site varies, generally work involves:

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