Heavy rain events reveal landslide problems on Pūhoi to Warkworth highway
Stuff - National: 18-July-2023
The Auckland Anniversary floods have reactivated a landslide that now threatens a new $880m motorway north of the city.
Open just a month, cracks have now appeared in concrete barriers, and an entire section may be moving under the Pūhoi-to-Warkworth highway.
Waka Kotahi has known for years the land in the area is unstable but thought the motorway would bypass it.
Instead, till-now undisclosed reports reveal the entire 18.5km-long project was beset by landslides for years, and the recent storms have made it worse, especially at one spot - an unstable slope above a stretch of about 200m of motorway by Mahurangi Bridge, near Warkworth
