Please adhere to all road closed signs and directions from any traffic controllers.
Geotechnical Investigations
The Lismore City Council (LCC), Flood Recovery – Roads and Bridges team recently secured interim funding for additional geotechnical investigations and survey to commence on several flood affected roads. Initial investigations took place in 2022 to inform the designers about the geological conditions and failure mechanism. This information was used to apply for funding to repair. Additional investigations are now required to inform the final design.
Geotechnical drilling is a type of drilling that is performed as part of the construction process to assist with better understanding a site. Investigations involve collecting rock and soil samples to obtain data regarding surface and subsurface examination. These samples provide valuable insights into the physical properties of the site, enabling engineers to design and construct remediation works to deliver roads that are safer and more durable.
Roads approved for investigations include Bice Road, Bishops Creek Road, Black Road, Blue Knob Road, Boyle Road, Cawongla Road, Cosy Camp Road, Cross Road, Gungas Road, Johnston Road, Koonorigan Road, Lillian Rock, Martin Road, Mountain Top Road, Oakey Creek Road, Orion Street, Rock Valley Road, Skyline Road, Stanger Road, Stony Chute Road, Terania Creek Road, The Channon Road, Tuntable Creek Road, Upper Tuntable Falls Road, Wallace Road, Whian Whian Road, Yeager Road and Zouch Road.
Cawongla Road
Significant changes to the traffic control measures at the Cawongla Road Landslide site, near Martin Road, were recently implemented. It was identified that the site was deemed unsafe due to technical issues with the traffic lights, including repeated battery charge depletion, and concerns about safety. Therefore, the traffic lights previously regulating traffic flow have been replaced with a “Give Way” sign and a “Stop” sign. This decision was prompted by multiple incidents of road users running the red lights, posing a serious safety hazard. The new signage system aims to simplify traffic management while mitigating potential hazards. All signage has been installed as per the amended traffic guidance scheme, and a comprehensive risk assessment was conducted before implementing these changes to ensure the safety of all individuals travelling through the site.

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.

Johnston Road - Landslip Closure
Share Johnston Road - Landslip Closure on Facebook Share Johnston Road - Landslip Closure on Twitter Share Johnston Road - Landslip Closure on Linkedin Email Johnston Road - Landslip Closure linkFollowing the February 28 and March 2022 flooding events, a road embankment landslip and tension cracking have occurred on Johnston Road, approximately 1km from Bangalow Road.
There is currently an interim road closure in place, allowing local access only. Geotechnical borehole drilling and the installation of inclinometers and piezometers will commence from Monday 22nd of August for one week (subject to weather and ground conditions). For the safety of motorists, a full road closure at the slip location will be in place for the duration of these works , with access granted to the properties located within the road closure only. To ensure your travels are not delayed, please review the road closure location to determine whether accessing from Eltham Road or Bangalow Road is most appropriate for your property.
Minor surface grade repairs, shoulder works and signposting for longer term traffic arrangements will also take place during this time. On completion of these works, the road will be reopened to one lane of traffic under a give-way arrangement at the slip locations. This arrangement will remain in place for several months until full remediation work commences.
A detailed site survey will be needed to get a full understanding of the landslips impact to the surrounding area, and to undertake the detailed design of the restoration. The survey will take approximately 2 days and will be completed after the geotechnical investigations, dates TBC. The survey will involve a combination of traditional (on foot) and drone survey, as per the extent in the following image. During the survey you may see surveyors working on the side of the road, or a drone flying overhead.
On-going monitoring of the inclinometers and piezometers will be required for a few months following the installation (timeframe will be confirmed from the data recorded). This on-going monitoring will ensure the slips behaviour / displacement is fully understood and the design of the remediation is robust and fit-for purpose. The on-going monitoring will involve a geotechnical engineer re-visiting the instruments once per week and taking readings by hand for approximately 30 minutes at each location. The instruments will be located within the shoulders of the road to enable the readings to take place with no impact to traffic. The approximate locations of the instruments are shown below.
The geotechnical investigations and survey will determine the detailed design and cost of the repair, which will be included in an application for funding to complete this work. Approval for funding is anticipated to be received by the end of August. Construction is planned to be commenced by the end of 2022, subject to approvals, contractor availability and weather.
Further updates will be shared via this page as works continue.
