Following the February 28 and March 2022 flooding events, Keerrong Road suffered extensive damage due to landslips and erosion. Funding has now been secured to complete restoration works.

The works will include excavation of slipped material adjacent to 1265 Keerrong Road, and reconstruction of the road embankment with increased drainage. The scope of works also includes a full maintenance grade of Keerrong Road, replacement of six damaged culverts and sprayed concrete erosion protection on Keerrong Bridge Road drainage outlets.

During the landslip remediation, the road will be fully closed at the works section from August 10th, requiring a detour via Pinchin Road. Motorists will be notified ahead of the closure via roadside signage, updated through northernrivers.myroadinfo.com.au, and on Your Say (details below). Residents will have access to their properties via Pinchin Road and The Channon Road but will be unable to drive through the landslip work zone.

Once landslip remediation is complete the road closure will move towards the Channon progressively, allowing pipes to be replaced. This moving closure will be communicated to affected property owners each day.

Further updates will be shared via the Community Updates tab of this page.

***Updated Friday 29th August

The side-track access for Fernside Bridge is structurally complete. Bitumen sealing will be completed on Monday 1^st of August (weather permitting), followed by removal of the bollards allowing heavy vehicle access.

Shotcrete application of the side track batters is scheduled for Tuesday 2^nd August (weather permitting), and may cause temporary delays to motorists wishing to use the side track while this work is completed.***

The side-track access for Fernside Bridge is on schedule to be open for vehicles by 29th July (pending weather). This will allow vehicles over 3.5tonne (GMV) access to and from Fernside Road, while repairs are scheduled for Fernside Bridge.

Additional pipes for higher creek flow have been installed as an added precaution. To finalise the works, shotcrete, sealing and tidy up will be carried out this week.

We appreciate the ongoing patience of the community while this side-track access for heavy vehicles was installed.

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.

Following the February 28 and March 2022 flooding events, a road embankment landslip has occurred on Johnston Road, approximately 1km from Bangalow Road.

There is currently an interim road closure in place, allowing local access only. Geotechnical drilling and investigation will commence from Monday 22nd of August for one week (subject to weather and ground conditions) (**Originally planned and communicated for week starting 1st of August 2022. Unforeseen ground conditions and increased project scope on other projects have pushed the schedule for specialist contractors).

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:

• Via the ‘Submissions’ tab of this article HERE.
• Email to council@lismore.nsw.gov.au
• Call to Council (02) 6625 0500
