Moss Vale Road

Roads and Maritime Services will carry out improvements on Moss Vale Road to provide a longer lasting and safer road.

Moss Vale Road at Cambewarra Mountain.

Updates and announcements

Essential maintenance work will be carried out on Barrengarry Mountain at night on Tuesday 30 and Wednesday 31 July, between 8pm and 4am, weather permitting.

Maintenance work will include cleaning and repairing drains, vegetation maintenance including inspecting and pruning trees, cutting grass and weed control, cleaning and repairing signs, collecting litter and rubbish and repairing guardrail.

The road will be closed to all traffic between Bunkers Hill Road and Myra Vale Road.

Detours will be in place via the Illawarra Highway, Macquarie Pass and the Princes Highway and motorists should allow up to an additional 90 minutes travelling time depending on origin and destination.

From Sunday 4 August, Roads and Maritime Services will be commencing slope repairs and rock fall prevention work on Moss Vale Road at Cambewarra Mountain.

The essential slope stabilisation work will be carried out at night over six weeks between Tourist and Kangaroo Valley Roads at Cambewarra.

Night work will be carried out from 7pm and 5am between Sundays and Thursdays from Sunday 4 August, weather permitting.

This will allow crews to secure the slope with tensioned mesh and bolts with the aim to eliminate the severity of future rock falls, and improve the safety of all motorists.

During the night closures, light vehicles can detour via Kangaroo Valley Road and Tourist Road. Heavy vehicles can detour via Princes Highway and Illawarra Highway.

At night between Sunday and Thursday motorists are advised to allow an additional 40 minutes travel time.

Daytime lane closures will be in place from Sunday 4 August to Sunday 15 September, between Mondays and Thursdays from 5am and 7pm.

Changed traffic conditions including lane closures, stop/slow traffic will be in place during day work to ensure the safety of motorists and workers.

Motorists are advised to allow an additional 40 minutes travel time during the evening and 15 minutes travel time during the day.

We expect the project to be complete by 15 September with no work being carried out on weekends, public holidays or school holidays.

Roads and Maritime thanks the community for their patience during this important work.

Community survey results

Following a trial of night closures on Moss Vale Road last year, we invited the community to give feedback on preferred times for regular maintenance work.

We thank all those who took the time to respond to our survey. More than 100 responses were received from the community and motorists.

The majority of respondents (74 per cent) expressed a preference for night closures. A number of people requested work start later than 7pm, and in response future planned maintenance work will be carried out between 8pm and 4am.

If there is a significant amount of work which cannot be completed in these working hours, it might be necessary to extend the times or days of the closures.

If you would like further information about the results of the survey please contact the project office on (02) 4222 3217 or email
