Update - 12 January 2023

Following Council’s continued advocacy for a fast determination by the NSW Government on their funding of the remediation and repair works at Cornwallis, Council has been advised by the Riverbank Erosion Taskforce that the Taskforce will be undertaking further analysis on the remediation and repair options for the Drain, Cornwallis Road, and surrounding area.

On Tuesday 13 December 2022, scientists and engineers from the Riverbank Erosion Taskforce visited the site at Cornwallis. There was representation from Infrastructure NSW, Public Works Advisory, Department of Planning and Environment, Resilience NSW, Office of Local Government and Transport for NSW.

The advice from the Taskforce is that it is expected that the options analysis will be completed by the end of January and used to inform the overall remediation strategy and funding decision.

Council will continue to hold the NSW Government to account on its commitment to timing and for the rapid approval of funding so we can get on with the job of repairing the damaged drain and reinstating the protection of the Cornwallis and Richmond Lowlands.

Update - 27 July 2022

There has been no change to the design intent, with the engineered bank protection and crest height of approximately 13.5m remaining the objective of Stage 1. However, this Stage 1 will now be approached as two distinct stages, stages 1A and 1B.

  • Stage 1A will target an earlier initial engineered protection of 7mAHD and additional measures to permit the dewatering of the significant area of erosion.
  • Stage 1B will continue on what is achieved by 1A, to achieve the original design intent of a 13.5m high crest and restoration of pre-flood protection

The final design of Stage 1A is anticipated to be finalised in approximately three weeks, with the procurement and early contracted works to follow that. As these timelines become clearer, we will update the community as we are able.

At the same time, detailed design works will continue on Stage 1B, as well as early consideration of Stage 2, the permanent restoration of the drain and riverbank.

Prior to the July flood, Council and Public Works Advisory had already commenced a process of reviewing the construction and delivery methodologies with a view to saving as much time as possible. Through this process, we identified a switch to pre-cast concrete box culverts would save a number of weeks of construction time and the order for the delivery of these culverts has already been placed. Whilst the decision to make this change was made prior to the July flood, the loss of a further approximately 20 pipes from the stockpile has meant that this will save even more time.

Thomas James Bridge and Settlers Road

Update - 6 January 2023

Preparations are underway and Council will soon call for expressions of interest to join the Community Advisory Committee. An email invitation will be sent to Macdonald Valley residents who have registered to receive  updates in the coming weeks.

Update - 16 December 2022

An online Macdonald Valley community meeting was held last night. A recording of the meeting can be found here Macdonald Valley Online Community Meeting - 15 December 2022 - YouTube

Endeavour Energy have now completed their work to reconnect and restore power to the area.

Update - 8 December 2022

An online Macdonald Valley community meeting has been scheduled for the evening of Thursday 15 December 2022. Macdonald Valley residents who have signed up to receive Council roads updates will have received an invitation to register their attendance.

Endeavour Energy has advised that it will close Settlers Road at Thomas James Bridge from 9am-4pm, 13-15 December 2022 to reconnect and restore power following flood damage.

Update - 27 October 2022

Council is waiting to receive approval from Heritage NSW on the reconstruction plans for the heritage retaining wall. Final design plans are being finalised in the meantime and will be completed within the next fortnight. Tendering will then commence. Plans include the retention of the convict-built sandstone retaining wall around a strengthened internal structure. Work is expected to commence in the first quarter of 2023, weather permitting.


Council is committed to keeping Thomas James Bridge on Settlers Road open as long as it is safe to do so, to ensure residents of the Macdonald Valley can stay connected.

To help ensure this, Council has invested in new monitoring equipment. This equipment will monitor the bridge and its approaches 24/7 and provide Council will real-time information on ground movement and weather conditions. This removes the need to close the bridge whenever there is wet weather. The bridge will now only close for safety inspections if significant land movement occurs.

This will eliminate the current automatic shut-down process of the road and bridge after 20mm of rainfall, allowing the bridge to remain open during rain as long as ground movement is not detected. Council will continue to monitor rainfall around the bridge as part of our decision-making processes.

We have also invested in 24/7 traffic control at the site to ensure the 5-tonne limit on the bridge is followed. This limit is in place to help prevent further damage to the road, which could force a permanent closure.

These investments will help ensure safe operation of the bridge until the permanent repairs can take place. Unfortunately, due to the location of the bridge, the surrounding geography and the heritage value of this 1830s convict-built bridge, this will be a complicated repair job. We are working closely with engineering, geotechnical and heritage experts to repair the road as quickly and safely as possible.


In the event of ground movement being detected, Council will alert the community that Settlers Road at Thomas James Bridge will need to be closed for safety inspections. Residents will be given approximately two hours notice.

Engineers will then conduct a safety inspection, anticipated to be within 24 hours of the closure. Following the inspection, Council will reopen the road if it is safe to do so, carry out make-safe works if possible before reopening the road, or keep the road closed if engineers declare it unsafe.


The system was operational from Monday 12 September 2022 and will be in place until the road and bridge is repaired and reopened without load limits.


Council is committed to providing ongoing updates to the community on the progress of repairs to Settlers Road.
