COMPLETED WORKS

Keerrong Road

Works were completed during October on Keerrong Road for excavation of slipped material and reconstruction of the road embankment. The works were carried out over 3 weeks and Council would like to thank the community for their support during the road closure.

Tuntable Creek Road

During October, new road signs were installed to assist with future road closures for Tuntable Creek Road. The extra signs will allow Council to notify residents of closures before reaching the closed site, helping to reduce detour times.

CURRENT WORKS

Crofton Road

This week, the first 500 metres of the road section will undergo restoration. Due to extensive damage, this section will be converted into a gravel road to facilitate the smooth flow of construction vehicles until the works are completed. Additionally, starting next week, pavement restoration works will commence from the other end of the road, and will be carried out for next two months ensuring improvements to enhance the road's overall condition.

Carabeen Place

Funding was secured for works to commence on Carabeen Road in October to repair damages caused during the 2022 natural disaster. The works includes restoring the batter to its original condition with rockfill and ensuring the drainage is adequate for future events.

Nimbin Road

Works are continuing for Nimbin Road, with the Site Km1 recently completing the placement of fine concrete blocks and backfill behind the retaining wall. The next steps are to backfill the underside of the road pavement layers and complete placement of the culvert outlet. Once completed, the road pavement construction will start along with earthworks around the retaining wall. Site Km4 recently completed the installation of 180 piles with the remaining piles to be completed at the beginning of November. Concrete pouring for the first section of the pile cap commenced late October with works currently underway for the first section of the 50m long blinding layer.

FUTURE WORKS

Traffic Barriers

Rural roads in the Lismore Local Government Area will have some of the creek crossings with damaged traffic barriers replaced during November. Approximately 15 crossings will be included as part of the Flood Disaster Recovery Funding Arrangements (DRFA) funding.

Terania Creek Road

Works are schedule to commence at Terania Creek Road on Bridge No. 3 during early November. These works will initially entail construction of a temporary side track next to the bridge so traffic can be detoured. After, works commence on installation of the new concrete bridge approaches. These works are expected to take approximately three to four weeks and will then move only Bridge No. 2, followed by Bridge No. 1. A VMS board will be installed prior to detouring traffic.

Rogerson Road

Funding is now approved for culvert works to Rogerson Road. During the Feb 2022 flood event, the Rogerson Road culvert had corrugated pipes that were severely scoured as well as the pipe bedding being eroded. The corrugated pipes will be replaced with precast concrete pipes to meet current engineering standards. Tendering is about to start for the works and members of our team are meeting with residents to discuss the works and notify them of any interruptions for the road.

COMPLETED WORKS

Bungabbee Road

Recently the Bungabbee Road bridge approaches works were completed to repair damages from the 2022 natural disaster. The works involved re-construction of the damaged approaches and re-instatement of guard rails, drainage, and scour protection around abutments.

Dudgeon Road Bridge

Works were scheduled and completed last month to repair the flood damaged Bungabbee Road bridge approaches. The works involved re-construction of the damaged approaches and re-instatement of guard rails, drainage, and scour protection around abutments.

Major Flood Recovery Works Map

Our interactive map recently underwent upgrades to improve user experience and include other flood recovery departments. Water and wastewater along with Flood Restoration Building projects have now been implemented into the map and in the coming month the flood restoration buildings will all be included. The map assists the community with finding efficient, up-to-date information about restoration works.

CURRENT WORKS

Nimbin Road

Works are continuing for the Nimbin Road landslips. Site Km1, located 1 Km from Nimbin has all the concrete works and piling complete with the installation of block wall in progress. This site is on schedule for the road to be fully open before Christmas. Site Km4, located 4 Km’s from Nimbin is currently undergoing construction of gabion walls, these are used for scour protection, which prevents soil from being washed away and helps strengthen the road. The site also has piling in progress with approximately 30% completed.

Keerrong Road

Works have commenced on Keerrong Road for excavation of slipped material and reconstruction of the road embankment. The works are scheduled for approximately 3 weeks, subject to weather, contractor, and material availability. A full road closure will be required around the works zone throughout the works period. A detour is available via Pinchin Road, motorists will be notified ahead of the closure via roadside signage, updated through www.livetraffic.com. Residents will have access to their properties via Pinchin Road and The Channon Road but will be unable to drive through the landslip work zone. 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.

COMPLETED WORKS

Terania Creek Road

Council recently completed maintenance work on Terania Creek Road to improve safety for road users. Guideposts were added, debris cleared, and large boulders removed which were partially blocking the road. The Flood Recovery – Roads and Bridges team would like to thank the community for their positive feedback and resilience during the flood restoration process.

Whian Whian Road - Simes Bridges

During the February 2022 natural disaster, the northern abutment of Simes Bridge on Whian Whian Road was impacted. Temporary works were carried out to restore access and the site is currently limited to one-lane traffic access under a give-way arrangement. The bridge is currently under restrictions and monitoring due to the flood damage. However, it was opened on August 10, to two lanes at reduced speeds to improve travel for residents. The bridge will continue to be sign posted limiting motorists to 40km/hr and speed bumps have been installed on the road entering the bridge.
