The rain event in early 2022 had severe impacts across Noosa Shire and resulted in extensive damage to roads, water crossings, and stormwater outlets.

The Black Mountain Road landslide is the biggest landslide on the Sunshine Coast in 30 years. Geotechnical assessments after the landslip determined much of the damage was below the surface, measuring as wide as a rugby league playing field and as deep as a five-storey building. Coming up with solutions to restore the area has been complex and involved extensive geotechnical and engineering investigations.

Hazell Bros commenced work on the reconstruction in October 2023. The works will stabilise the road with depths between 5m to 25m across the 130m span and improve subsurface drainage.
