Flood Restoration - Roads & Bridges Update (Jan 2024)

COMPLETED WORKS

Geotechnical Investigations
During the month our contractors closed single lanes for works on Orion Street, Skyline Road South, Tuntable Creek Road, and Zouch 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. All landslip geotechnical investigations have now been completed with the bridge investigations underway and expected to also be completed by the middle of February.

Eltham Road
Recently, funding was secured to install guardrail on Eltham Road. These works were completed late January with a road closure in place around the site. There was a road closure between Houghlahans and Humpty Back roads and we thank the community for their patience during the road closure.

Quilty Road
Works were recently completed on Quilty Road to repair pavement damage and replace a culvert to return the road to pre-existing conditions. Thank you to the residents for their patience and support during the works.

Tuntable Creek Road
As the safety threshold had been exceeded, a road closure was triggered for Tuntable Creek Road on Wednesday 17 January 2024 at the landslip site, between Rose Road and Beardow Road. The shut down was to ensure the safety of motorists and to allow for further monitoring. Geotechnical experts were on site the next day to inspect the site and determined it could be reopened. The road reopened Thursday morning 18 January 2024. The new signs installed in October 2023 assisted to reduce detour times allowing Council to notify residents of the closure before reaching the closed site.

CURRENT WORKS

Nimbin Road
Works are continuing for Site 4km on Nimbin Road, after the successful completion and opening of Site 1Km. Recently work crews completed implementation and maintenance of the erosion control following the heavy rainfall. Placement of approximately 70% of the GWS (No Fines Concrete Blocks) on top of the pile cap and approximately 60m of drainage layer and selected fill behind the retaining wall were also recently completed.

Guardrails Project
During the past month our guardrails project has been underway, replacing or installing new guardrails. This is multisite works to repair traffic barriers at road sections damaged during the 2022 natural disaster. Generally, the sites are at road sections over creek crossings. Each work site will require traffic control and the repair will generally be completed within 2 days. Recently, the work crew worked on Eltham and Boatharbour Road. Other road closures will be updated as scheduled work on Live Traffic.

Terania Creek – Bridge Updates
The Terania Creek bridge project is underway for bridge 1, 2 and 3. The bridge approaches and guard rail footings completed for bridge 3. Commencement on bridge 2 is scheduled for early February.

FUTURE WORKS

Dorroughby Road
The road closure for Dorroughby Road was unfortunately delayed until 12 February with expected competition approximately 26 February, subject to change pending weather conditions. Works will involve scaling of boulders and the clearing and reformation of a table drain to return the road to pre-existing conditions. Road closure will be required around the works zone with the section located approximately 500 meters from the Dorroughby Road/Corndale Road intersection, between 791 Corndale Road and 65 Dorroughby Road. Motorists will be notified of the closure via roadside signage and updated through www.livetraffic.com. Emergency services vehicles will be accommodated. Please adhere to all road closed signs and directions from any traffic controllers.

Rogerson Road
A culvert replacement is planned for late February 2024. These works will require a road closure for up to 10 weeks subject to weather and resources availability. The existing culvert was damaged in the February 2022 natural disaster and has funding approved for a replacement structure with concrete pipes.

Newton Drive
A number of minor up slope landslips and a single pipe culvert are scheduled to be repaired during February. Works will involve scaling of boulders and the clearing and reformation of a table drain to return the road to pre-existing condition. Works will be completed under traffic control and will have minimal impact on the residents in this area.

Rosebank Road
Rosebank road slip will have restoration works completed during February. The works involve reinstating the property access track and restoring the batter and table drain along the road edge. Works will be completed under traffic control and will have minimal impact on the residents in this area.

Johnston Road
Minor works on a damaged drainage culvert along Johnston Road will be completed in February. This will involve reinstating a rock blanket that was washed away in the February 22 Flood Event. Works will be completed under traffic control and will have minimal impact on the residents in this area.

Leycester Road
Council wishes to advise funding has now been secured to reinstate the road to a suitable standard to ensure the community are able to travel safely along this road. The works are schedule to occur July 2024, notwithstanding another disaster event and subject to weather conditions, resources, and contractor availability. During works traffic will be impacted as the works will be carried out under Traffic Control stop/go arrangement and a reduced speed limit. At times traffic users may experience long delays to allow construction of the new pavement. Access to property driveways may be impacted or restricted at times however will ensure property owners are notified prior to this occurring. Motorists will be notified of the upcoming roadworks with VMS boards and updated through www.livetraffic.com closer to construction commencement. Emergency services vehicles will be accommodated if required. Please adhere to all road signs and directions from any traffic controllers and ensure extra care is taken around workers on foot.

Eureka Road, Graham Road & Haywood Lane
The design plans have changed for Eureka Road, Graham Road, and Haywood Lane. These sites were originally scheduled for culvert replacement; however, funding has been successfully acquired to upgrade these locations from box culverts to bridges. Currently, design for the project works is in final stages with the bridges due to be delivered to Council late February. The works are to be scheduled after delivery, this is subject to change pending weather conditions, resources, and contractor availability. We apologise in advance for any disruptions you may experience while we carry out this essential work. These works will involve removing the existing infrastructure at each site and preparing the area for bridge construction. To minimise impact to residents and traffic flow during the construction work a temporary track will be established as a side road. The works will take approximately 6 weeks at each site.
