Waka Kotahi NZ Transport Agency is advising that State Highway 25 between Hikuai and Opoutere remains open for light vehicles for essential travel only due to further deterioration of the underslip.
Contractors were cutting into the bank to extend the road further away from the advancing underslip this afternoon. They are keeping traffic flowing as much as possible but periods of stop/stop traffic management are required. Road users should expect long delays.
The road will have to be fully closed for a period of time later today while contractors construct the pavement for the road widening.
The road was originally closed early yesterday morning following a washout caused by heavy rain over the weekend.
The ground conditions in the area remain highly unstable. Contractors are constantly monitoring the site to ensure it remains safe, and the road may be closed at short notice should conditions deteriorate further.
