Flood Restoration - Roads & Bridges

Works are commencing on making a temporary side-track over the slip at Koonorigan Road, suitable for local access.

This follows geotechnical investigations taking place, where instruments were installed to monitor progressive movement and to determine the depth of the failure plane. A geotechnical engineer will be engaged to provide a final design to rectify the slip.

Funding approval has also been received to heavy patch the seal on The Channon side of the slip. This work is currently being scheduled.

Council has received feedback from a number of local community members and motorists regarding Koonorigan Road, and are looking forward to restoring access. We appreciate your patience as this work continues.

Flood Recovery Heavy Patching Program –

Restoration of road surface, possible change in road level.

Segments of the following have been identified for heavy patching works to repair flood damage to road surface.

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:

Slumping of the road embankment on Orion Street has worsened since the February and March 2022 flooding events. Minor works have since been undertaken to seal the tension cracks and ensure safe passage for vehicles.

Orion Street will now undergo works to remediate the damage. Geotechnical drilling to determine the depth of the slip plane and options for remediation will be undertaken the week starting 18th July, for minimum 1 week pending the ground conditions.

To ensure access for necessary equipment and works in this section, a full road 24-hour road closure is required from Monday 18^th July until Friday 22^nd July 2022 (subject to weather and ground conditions).

Local access only will be available for Orion Street from Dawson Street. The road will be closed from Molesworth Street to Dawson Street, with detour via Conway Street.

Signage of the Orion Street closure will be in place to notify motorists and updated through northernrivers.myroadinfo.com.au. Motorists are recommended to use the roads over Fawcett Bridge to access the CBD and surrounds from North Lismore.

Scheduling of the Orion Street works were planned for the school holiday period. Unfortunately due to the ground conditions following recent wet weather and subsequent availability of specialist drilling contractors, this work was unable to go ahead as planned. To ensure geotechnical drilling and installation of instrumentation to monitor the slump is completed, these works cannot wait for the next school holiday period.

We are looking forward to providing a long term solution to the Orion Street slumping, and appreciate the patience of our community.
