Moss Vale Road repair work

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.

As part of the natural disaster recovery response, we'll be carrying out survey investigations at four sites on Moss Vale Road at Barrengarry Mountain. These investigations are non-intrusive and noise from this work is expected to be minimal. A map showing the work areas is below.

We’ll be working between 8am and 4pm from Monday 16 to Friday 20 June 2025, weather permitting.

Traffic control, single lane closures and a reduced speed limit of 40 km/h will be in place for the safety of workers and motorists. Motorists are advised to allow additional travel time, with delays up to 10 minutes. 

Transport for NSW has more work in planning stages for this year to repair landslip damage on Moss Vale Road.

This follows an intensive program last year that saw work carried out at eight landslip sites on Cambewarra and Barrengarry mountains.

Work is scheduled to start in early March to complete the last stages of major repairs at six sites on Cambewarra Mountain.

This work includes installing mesh and spraying concrete over the steep slopes to help prevent erosion during future severe weather events.

Work starts on Monday 3 March 2025 and is expected to take three weeks to complete, weather permitting. Work hours will be 6am to 6pm, Monday to Friday.

During these work hours, the road will be reduced to a single lane and with a reduced speed limit of 

40 km/h between Carrington Road and about 800 metres west of Cambewarra Lookout Road. 

Portable traffic lights will alternate traffic direction through the work area. The road will return one lane each way outside these work hours.

Motorists are advised to allow an extra 15 minutes’ travel time and drive to the conditions, including observing the 40km/h reduced speed limit, for the safety of workers.

We have further work planned to start later in the year at both the southern and northern approaches to Cambewarra Mountain.

Transport will inform the community before work begins in these areas.

Single lane closures for landslip repairs 

Sunday 23 March - Thursday 10 April, 8pm to 4am, Sunday to Thursday nights 
Moss Vale Road closed between Barfield and Kangaroo Valley roads for maintenance work

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.

Following the 2022 extreme weather events, 50 landslip sites along Moss Vale Road were recorded and added to Transport for NSW’s  natural disaster recovery project register. The maps below show the location of the sites on Moss Vale Road at Barrengarry and Cambewarra Mountains.
