A section of Cipero Road between the 8 and 8.2 km mark has been closed due to a landslip.
The Works Ministry says slippage was initially noted during routine inspections in early July 2021.
Recent heavy rainfall however has worsened the situation, with approximately 65% of the roadway now affected,
The section has been closed to vehicular traffic as it has been deemed hazardous to road users at this time.
Persons can instead use alternative routes.
The Ministry says it is pursuing emergency slope stabilization work in the interim, following which the road will be reopened.
