Responding to high priority road hazards caused by weather eventsOur local road network has suffered significant damage following the February 2022 flood.

Don't remove or tamper with traffic lights or road signage – it puts people at risk and it's illegal. Read more.

The very large volumes of emails, letters and calls since the floods are impacting on recovery works. Before you contact us please review the information on this page and read our weekly flood recovery update, which provides you with the latest news on how the Tweed is recovering and rebuilding following the floods. Read more about your part in roads flood recovery.

As our road crews and contractors undertake the enormous task of fixing our roads, we ask motorists to please:

  • have patience
  • slow down and drive to the conditions
  • understand that some repairs are only temporary until a more permanent fix can be completed
  • be aware of changed traffic conditions.

Significant repairs

Landslips are responsible for most of our expected long-term road closures.

Geotechnical investigations are underway, however the design and construction of these repairs will take many months to complete.

Tyalgum Road slip site 2023.pngWork to repair the significant landslip on Tyalgum Road is set to progress, with a $16 million contract awarded to local construction company SEE Civil Pty Ltd.

The contract was awarded following an extensive tendering process, supported by a Letter of Agreement from Transport for NSW, and will allow the contractor to progress design work from 30% to 100%.

A further $4 million will go towards additional costs on the project, such as land acquisition and site work, bringing the total cost of the Tyalgum Road landslip repair to $20 million.

SEE Civil is also the preferred contractor for the $2.3 million project to restore the two slips on Limpinwood Road – the main alternative access route to Tyalgum village. Transport for NSW is currently assessing the proposed works prior to Council awarding of the contract.

Design work for Tyalgum Road is expected to take until late May to complete, with work expected to start on site around the same time.

The contractor’s design work will include the provision of temporary access through the Tyalgum Road site, with the aim for this to be in place by the latter quarter of this year.

Limpinwood Road will remain open to one lane as per the current situation while reconstruction work takes place, which is also expected to start at the end of May.

Mayor of Tweed Shire Chris Cherry said it was great to finally see progress on restoration of the Tyalgum Road landslip.

“This is the biggest and most complex of the Tweed’s landslips caused by the devastating flood of February-March last year and today’s announcement represents a significant milestone in the Shire’s recovery,” Cr Cherry said.

The major landslip on Tyalgum Road is about 950 metres east of Van Den Broek Road. There is another slip about 1 km west of this major landslip.

The damage site is more than 100 metres in width, some 60 metres in length and appears to comprise of some 6-10 metres depth of material which has slipped.

One-way traffic arrangements at the secondary landslip site, about 1 km west of the main slip, will remain in place.

 

The process of rebuilding

The list below summarises the high level processes we need to follow to fix the landslips at Tyalgum Road. Given our current knowledge of the sites, it’s difficult to provide accurate dates for each part of the process. There may be opportunities to run some of those in parallel however, we won’t know until we start to confirm the preferred solution. The outline below will give you an idea of why the works will take at least 12 months.

  • Geotechnical procurement (completed)

Fixing landslips is a complex engineering task. It is crucial that the foundation of the slip is properly stabilised to prevent a similar failure occurring in the future. Specialist geotechnical engineers are used by Council to investigate the best option suited to Tyalgum Road’s specific site conditions. Only then can the missing piece of road be constructed over this new foundation.

The geotechnical assessment is broken up into 2 stages:

  • Stage 1 is a preliminary assessment to make recommendations about the short term safety of the site.
  • Stage 2 involves boring holes to investigate the soil in and around the slip including scientific testing, this information is used to determine options to fix the slip.
  • Design and construction tender (awarded)

We draft a design and construction document in preparation for the tender process. We then advertise the tender, evaluate all submissions then select the preferred tenderer based on the NSW legislation and our Procurement Policy which define specific processes and minimum timeframes. The tenderer then develops the design for approval by Council and Transport for NSW.

  • Environmental assessment (ongoing)

All work Council undertakes, including the repairs required on Tyalgum Road, requires approval under the Environmental Planning and Assessment Act – in much the same way as residents need a Development Approval to carry out renovations on their homes. This is to ensure there is minimal environmental impact during the construction of the work and that the final construction won’t cause any additional impacts to residents or the environment.

  • Consultation with the community (ongoing)

We will consult with residents and businesses who will be directly impacted by the works to ensure they are not adversely affected by our activities. If they are, we will put in place measures to minimise these impacts.

There are several properties through which we are likely to require access to carry out the work.

  • Construction

At high level, a typical construction process to fix significant damage such as those sustained along Tyalgum Road would involve site establishment, excavation of slip areas, foundation works, wall construction or stabilisation structural works as well as earthworks, drainage, road subbase, pavement, line marking and safety barrier works.

Kyogle Road adjacent to the Tweed River on the way to Uki (5).JPG Civil Mining & Construction Pty Ltd has been selected for three contracts worth more than $28 million to restore three sites on Kyogle Road.

At its meeting on 2 March, Council selected Civil Mining & Construction Pty Ltd  to commence on completing designs and construction of the landslips on Kyogle Road.

Transport for NSW is currently assessing the proposed works prior to Council’s awarding of the contract.

Guardrail installation has been completed between Palmers Road and Clarrie Hall Dam Road.

Motorists are advised to watch for changed traffic conditions and to follow workplace signage.

Speed zones are enforceable and are designed to keep both road crews and motorists safe.

Major landslips on Kyogle Road are located 500 m to 1.6 km west of Byangum Bridge.

Other slips along Kyogle Road allow 2 way traffic to pass but heavily constrict traffic. We ask motorists to proceed with caution.

Reserve Creek Road landslip

A significant step forward in the repair of Reserve Creek Road has been achieved with the Transport for NSW confirmation to award the contract to SEE Civil Pty Ltd.

The contract, worth $5,978,367, will allow SEE Civil Pty Ltd to progress design work from 30 percent to 100 percent completion with initial work expected to start after Easter.

Work on site can then commence with the aim of having a temporary access part way through construction roughly 7 weeks after site work begins.

The Reserve Creek Road landslip presents a major design and engineering challenge, with the road significantly undermined by a 15-metre high, near-vertical landslip which occurred during the February-March flood.

Transport for NSW has confirmed funding approval to cover the cost of repairs.

Council is aware of the issues facing the local community and the significant connectivity impacts associated with the road closure and has therefore prioritised the possibility of providing a one lane temporary access with the contractor which will be confirmed during the remaining design period.

A section of Beltana Drive remains closed following advice from geotechnical consultants about the road’s safety.

Beltana Drive landslip

The damage, caused by the heavy rains of February and March in 2022, resulted in the collapse of the scarp.

To ensure the ongoing safety of road users, the road has been closed at the landslip site.

Beltana Drive is a loop road therefore access to all residents can be maintained. Although some residents will be inconvenienced due to slightly longer travel times.

Bus and rubbish collection services have been advised of this and arrangements have been made for these services.

Roads are closed to keep motorists safe. Please don’t remove or tamper with road closure signs or barriers – it is a serious offence and could result in someone getting hurt or killed.

Geotechnical borehole drilling is being carried out to provide information for future works on site.

Temporary repairs have restored 2-lane access on Tweed Valley Way.

This section of Tweed Valley Way is both a roadway and a hydraulic structure. It also provides a crossing for water, sewer, power and telecommunications. It will require various investigations, consultations with local stakeholders, environmental assessment and approvals, engineering design and planning approvals.

Council has applied for funding through the NSW Government Infrastructure Betterment Fund to carry out the work and is waiting from a response to the application. 

A specialist contractor will then be engaged to carry out the works. Given the site’s complexity and other pressing priorities across the Tweed, the permanent works may take up to 2 years to complete.

Flood recovery works

Last updated 7 March 2023

Major work has been completed on Scenic Drive while design work continues on the major landslips around the Tweed. We are also working on strategies to fast track the remainder of the repairs.

Council has completed 100% of Emergency Works and completed all Immediate Reconstruction Works. 

Planning and maintenance will continue as new works are identified. Priorities are based on public safety, road hierarchy and efficiency of works.

As a result, residents may notice some damages are fixed as a crew works through a road and other damages are left for another time.

Our standard procedure is to notify affected residents and visitors of planned works via a letterbox drop. However, in the interest of expediency, this may not be possible during these flood repair works.

We apologise for any inconvenience and ask for your patience as we work through our roadworks program.

Our road crews and contractors will be making some permanent repairs to the following roads:
