COMPLETED WORKS
Crofton Road
Excitingly, road pavement restoration works on Crofton Road were completed on 6 June. The works began in November 2023 to remediate significant damaged caused during the February 2022 natural disaster. Construction involved resealing 3 kilometres of road, installing guideposts, and replacing two culverts. During these works, the road remained open with stop-go traffic conditions, and we would like to thank the community for your patience during this time.
Dorroughby Road
After listening to the concerns of residents, work crews organised for contractors to install a new guardrail on Dorroughby Road to improve road safety. Thank you to residents for your positive feedback following the installation.

CURRENT WORKS
Blue Knob Road
Work is underway on the first of four landslip sites along Blue Knob Road. Contractor CMC is currently focused on the site closest to Nimbin, where they are constructing two soil nail walls. Once this stage is underway, they will proceed to establish the second site for excavation. The restoration of all four landslips in this project is anticipated to span 10 months, subject to weather conditions.

Eureka Road, Graham Road & Haywood Lane
The side tracks and earthworks are completed at all three sites. On Eureka Road piling is now completed and installation of a new Inquik bridge is planned for early August. Piling commenced on Haywood Lane 26 June and is also scheduled for Inquik bridge installation early August. Following these works, piling will begin mid-July on Graham Road due to essential energy power outage required to commence these works. Throughout construction, road users will continue to utilise the side tracks to minimise traffic disruption.

Gravel Roads – Multiple Sites
Efforts persist in grading over 120 kilometres of 53 unsealed gravel roads, which suffered substantial damage due to declared natural disasters in December 2023 and April 2024. The most severely affected roads receive highest priority to expedite critical route restoration. This ambitious project, one of the largest of its kind, involves Council deploying six distinct work crews, strategically clustered geographically to optimise efficiency and resource allocation. Recently, HXR conducted grading on Gungas Road and expressed gratitude to the supportive residents they have encountered to date.

Leycester Road
Ongoing efforts are focused on repaving the entire length of Leycester Road, covering approximately 3.6 kilometres from Kyogle Road to Bice Road. Construction entails a granular overlay of the existing road surface, resealing, and upgrades to stormwater drainage. Anticipated to span approximately six months, from July to late December 2024 subject to weather conditions. the construction will impact traffic. During this period, road users will be impacted and can expect delays. During the works, residents will be impacted while construction is carried out under traffic control stop/go arrangement and a reduced speed limit. At times road users may experience long delays necessary to facilitate the construction of the new pavement.

Newton Drive
Construction has commenced on a second minor upslope landslip further up Newton Drive. Crews have taken advantage of favourable weather conditions during the past month proceeding to the final cleanup and rehabilitation phase. The remaining work involves sealing the road at the landslip site and the replacement of a single pipe culvert. We extend our gratitude to the community for their patience during the minor disruptions to traffic flow.

Rogerson Road
Benefiting from favourable weather conditions, the culvert works on Rogerson Road have advanced. These efforts entail replacing outdated steel drains with new cement pipes. Over the course of the month, the pipes were lifted and positioned in place, and the blinding was poured for the headwalls.

Stony Chute Road
Earthworks are now complete and site rehabilitation is underway. Drainage structures are on track to be completed by the end of the month. On drainage completion, final works include road resealing which will involve stop/go traffic control.

Three Chain Road Quarry
Located on 12.9 hectares, the formerly abandoned Three Chain Road Quarry has excitingly reopened. The site now serves as a revenue stream to support the creation of a rehabilitated green space and koala habitat. Managed by the Flood Restoration Roads and Bridges team, the quarry is excepting Excavated Natural Material (ENM). Any material disposed must undergo rigorous testing with documented proof of addressing strict environmental standards.

Terania Creek Road
Thrillingly, construction works on Bridge 3 are now complete. Crews have moved onto Bridge 2 where a side track is in place and works are underway for new approach slabs and restraint bracket installation. After, crews will relocate to Bridge 1 to construct a side-track early to mid-July and commence approach works.

Upper Tuntable Falls Road
Landslip remediation works are nearing completion on Upper Tuntable Falls Road including minor grading and drainage works. Images below illustrate the progress during the past few weeks for remediation at the site.
FUTURE WORKS

Urban Drainage
Approvals have been received for the urban drainage works. The project will soon be tendered to local contractors for pricing, with an anticipated start date in four weeks.

Gwynne Road
The pavement repair designs for Gwynne Road, covering the initial 1.2 kilometres from the Jiggi Road intersection, have been finalised. The project will soon be tendered to local contractors for pricing, with an anticipated start date within the next 4 to 6 weeks.
