Waterfall Way between Thora and Dorrigo is likely to remain closed in both directions for several days after landslides at Myers Bluff, Thora on Friday.
A council vehicle was struck by debris during one of the landslides but thankfully no one was injured.
Bellingen Shire Council said Transport for NSW Geotech engineers would attend the site as soon as possible.
"It is necessary for weather to stabilise before we can undertake any rectification works; however, council is preparing earthmoving equipment to remedy clean up as soon as the site is deemed safe."
A local drone operator sent the following footage that shows the extent of the damage:
A further slip has occurred on Gordonville Cutting on Waterfall Way closer to Bellingen, which has restricted vehicular access to a single lane.
