Tasman Highway - through the Sideling repairs
The Sideling reopened in February 2023.
The Sideling reopened Monday, 27 February 2023
The Tasman Highway through the Sideling reopened to traffic from 7:00 am on Monday, 27 February 2023 to all vehicles except articulated heavy vehicles, following extensive repairs to damage caused during last October’s floods.
There will continue to be lane closures and reduced speed limits along the highway as work continues on several smaller repair sites, as well as the separate Sideling Upgrade project. However, at least one lane will remain open at all times.
The completed repairs involved a massive rebuilding and reinforcement of a steep embankment that collapsed due to the severe rainfall, undermining the highway and requiring its closure.
The landslip went several hundred metres down the bank. A 7-metre high support structure of 190 rock-filled gabion baskets has been constructed to support the road. To ensure a stable foundation for the baskets, it was necessary to excavate a couple of metres down.
Contractors worked seven days a week following the flood damage to rebuild and reopen the highway as soon as possible and minimise the disruption to the local community.
We thank all members of the community for their patience and understanding while we completed the repairs.
Work will also continue on the Sideling upgrade project with the same lane closures and reduced speed limits in place as before the highway was closed. The Sideling also remains closed to articulated heavy vehicles while this project progresses. It is due for completion in May 2024.
