ROADS & BRIDGES FLOOD RESTORATION PROJECT UPDATE
Please note, several road and bridge projects progressing concurrently, below are updates for some projects progressing this month. Please check the 'Projects By Name' and select the road name for latest updates. Additionally, if there is a road you would like specific flood restoration updates on, please register your contact details via our notification list form.

COMPLETED WORKS

Cawongla Road
Recently work crews made the road wider on Cawongla Road around the landslip area. You can locate the exact region through viewing our IntraMaps and selecting ‘Major Flood Recovery Works’ these works are found at damage No. DM00666.

Geotechnical Investigations
During the month our contractors closed Wallace Road and Oakey Creek Road to perform geotechnical investigations. This involved using a drilling rig to understand subsurface conditions. We would like to thank residents for your patience and resilience during this time.

Koonorigan Road
Road maintenance works were recently completed for Koonorigan Road with a new seal laid to improve the road condition and impact on residents. Geotechnical investigations were also performed during this period, and we would like to thank the community for their continuing patience.

CURRENT WORKS

Carabeen Place
Carabeen Place is progressing on schedule with asphalt now completed at the site. Work crews are finalising works to prepare for a reopening of the site. Thank you to the residents for your patience during the works period.

Nimbin Road
The works are progressing on schedule for Nimbin Road with Site Km1.0 is on track to open before the end of the year. The total extension of the remediation works for the site is 120m with 239 piles now installed with the total length of 3,226 linear meters. Additionally, 150m³of concrete have been used for the construction of the pile cap with 611 blocks placed on top of the pile cap to allow the reconstruction of the road.

FUTURE WORKS

Zouch Road
Following the February 2022 natural disaster, Zouch Road suffered extensive damage. Funding has now been secured to complete geotechnical investigations using a drilling rig to understand subsurface conditions. The full road closure will no longer be in place as work crews have been able to contract a smaller drilling rig for the works. A smaller rig allows the team to establish a temporary track for resident cars to drive through the work zone to access their properties during the works period. As a result of this change, the works will change to occur from 7am to 5pm between the 6th to 15th of December. The works are located approximately between the intersection with Stoney Chute Road and to the west along Zouch Road approximately 400m. Motorists will be notified of further information via roadside signage and updated through www.livetraffic.com. Emergency services vehicles will be accommodated during these works. Please adhere to all road closed signs and directions from any traffic controllers and expect delays. We apologise for any inconvenience. Further information can be sourced on the original works post:

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.

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, 15^th August 2022 referring to ‘Flood Recovery Heavy Patching Program’. Feedback can be received via any of the following:
