Tyalgum Road, about 950 metres east of Van Den Broek Road, will remain closed for at least 6 months after a geotechnical investigation found the roadway too dangerous for temporary repairs.
Council will excavate the remaining road to prevent motorists from by-passing barricades blocking the roadway, which was severely damaged by a major landslide during the February 2022 flood.
A ramp developed by motorists to drive through the major slip on Tyalgum Road has been removed by Council crews and motorists are reminded not to attempt to cross this dangerous slip.
It is expected Tyalgum Road will be closed for 6–12 months, in the area of the landslip.
Council’s Director Engineering David Oxenham said the geotechnical assessment indicated the landslip could very likely be subject to ongoing movement, particularly following any additional rainfall.
“To ensure the safety of road users, Tyalgum Road will remain closed until permanent repairs can be made,” Mr Oxenham said.
“Unfortunately, there are no safe and reasonable short-term repair options for this road, which will require significant works to achieve a level of safety.
“The landslip is affecting some 110 metres in road length and some 50 metres in height in the slope above the road. A safe, temporary track near the slip cannot be built as the slope both above and below the road is relatively steep.
“Further geotechnical investigations will be undertaken to identify failure mechanisms, the depth of failure planes and develop suitable options to repair the road.
“To those who use Tyalgum Road, especially residents of the area, we apologise for any inconvenience and ask for your patience as we work towards a more permanent repair.
“Roads are closed to keep motorists safe. Tampering with road closure signs or barriers is a serious offence and could result in someone being hurt or killed. Please don’t remove or tamper with them.”
One-way traffic arrangements at the secondary landslip site on Tyalgum Road, about 1km west of the main slip, will remain in place.
Motorists are advised to access the village of Tyalgum via Chillingham until roadworks on Tyalgum Road are completed.
Further geotechnical assessments are also being undertaken at several other sites in the Tweed, including at Scenic Drive at Bilambil Heights and Reserve Creek Road where major landslips also occurred.
Council estimates damage to the Tweed’s road network by the recent flood could cost around $40 million and take up to 2 years to repair, with more than 1,900 repair jobs already logged.
