Due to the nature and high number of damages incurred, works are being finalised on how best to provide timely improvements for the community and road users.
Road surface conditions
Pavement repairs have been approved for funding to address the road surface conditions. These works are currently being scheduled for the entire sealed road damage package. Unfortunately, this is taking longer than expected due to constraints on resources and the prolonged period of wet weather. Dates of these works will be released shortly, with temporary measures such as gravel fill being implemented to assist road users in the interim.
Road closure – between Rose Road and Beardow Road
The road closure is a result of approximately 280m of road alignment between Rose Road and Beardow Road being affected by considerable damage. The road in its current condition presents two significant landslip damage locations.
To date Lismore City Council have completed geotechnical investigations of the sites and undertaken initial design option analysis. GHD have been appointed as the Lismore City Council Road and Bridge Recovery Design Partner, with Tuntable Creek Road their top priority site for urgent design and restoration activities.
The landslip sites are extremely challenging from an engineering perspective. The soil is observed to be colluvial and residual soils derived from basalt, with large boulders and cobbles throughout. The main damage location leaves no usable width of the original roadway.
The failure has exposed several large boulders that may indicate older landslide materials naturally in place at the site. The landslide damage extends some distance below the road embankment to Tuntable Creek. Figure 1 below shows an aerial of the main landslip.
There is significant movement at the location of the landslip and the depth of loose material makes stabilisation of the site a major engineering challenge.
The second site presents a now split roadway with tension cracks on the downhill side and a heaved uphill side of the roadway. It is assumed that this is a compound landslide with both up and downhill damages incurred. Damage at road level is significant. Figure 2 shows the visible tension cracking and deformation from the landslide movements. Observations indicate that both these areas of extensive damage to the road are related, and likely part of the same landslide movement.
The large extent and length of this cracking suggests that a larger underlying failure may be present than is currently visible. This poses the risk of larger landslides in future events.
Provision of temporary access
Given the time that a permanent solution will take to design and implement, Council is currently investigating the construction of a temporary access widening at the location of the main slip. The current soil conditions and terrain makes such a solution very difficult to implement, requiring advanced geotechnical engineering solutions and ongoing monitoring to ensure the safety of users. A temporary access design is being prioritised and, if feasible, will be implemented in the shortest possible time frame.
Council understands the significant impact of this road closure on the local community, and appreciates the feedback received to date. In recognition that permanent restoration will take a significant amount of time, the following will be carried out:
- Regular updates through online channels and direct consultation with community
- Additional notification for road users of the surface conditions and road closure
- Temporary works to address road conditions until permanent works are completed
- Review of the Nimbin Community Disaster Resilience Plan and The Channon and Surrounds Disaster Resilience Plan

Terania Creek Road - Segments have been identified to be included in the Flood Recovery Heavy Patching Program, which will provide improvements to the structural integrity of the road and driving conditions for road users. Geotechnical monitoring of the slip site is underway, as is procurement of specialist contractors and designers. Once works are complete at the slip, bridge approaches will be repaired and the road graded.
Town Road - Bridge structure has been procured and works are expected to commence in late 2022.
Tuntable Creek Road - Drilling has been undertaken on the slips, with geotechnical instrumentation installed to monitor movement to best inform the required structural design. Unfortunately, there is a shortage of suitably qualified geotechnical engineers at present. Council has started the procurement process to engage a designer and contractor to undertake restoration works. Additionally, funding has been received to undertake pavement repairs on damaged sealed-sections of Tuntable Creek Road, which is scheduled for October.

These works are subject to change to due weather conditions, availability of contractors and funding. Updates will be posted on this article.Shall you wish to be kept up to date directly, you can register your details via the Your Say ‘Submissions’ tab HERE. Alternately, please contact Lismore City Council via email council@lismore.nsw.gov.au or call (02) 6625 0500 to register your details. Please reference ‘Flood Recovery Heavy Patching Program’.
How will the works affect traffic?
Roads will be open to residential access only during the time of works. Traffic controls will be in place, which will cause minor delays and disruptions. Please note roadside signage, updates on myroadinfo and updates in the online Your Say article for communication about temporary disruptions to your property access during this period.
What do the works involve?
These roads need to be fixed to improve the structural integrity and driving conditions for road users. Works include cleaning drains and culverts, cutting off high road shoulders, digging out and replacing soft spots with rock. The gravel overlay is placed where required, before stabilising with the addition of slag lime. This is then compacted, trimmed, and sealed. Followed by line marking edge line.
The road surface may receive a final wearing seal several months after the initial bitumen seal has cured.
This pavement overlay may potentially change road levels between 0mm to +150mm and resurfacing of the existing road width due to additional layers of new road base material.
All driveways that intersect the road will match any changes to the road profile. If there are any changes, you will be contacted should your driveway/access need modification. We will also do maintenance to roadside drainage as needed.
What happens now?
If you wish to make comment on the works, we ask that you do this by 4pm Monday, 15th August 2022 referring to ‘Flood Recovery Heavy Patching Program’. Feedback can be received via any of the following:
