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.
