The Waitaki District Council has erected a protective fence along a section of Beach Rd in Kakanui after another slip occurred over the last week.
Temporary fencing has been put up just north of the existing under-slip to prevent vehicles from using the road’s shoulder and to act as a visible warning if more of the shelf breaks away.
Waitaki District Council roading manager Michael Voss said it was difficult to pinpoint exactly when the latest slip occurred, as the road itself was not damaged, but it could have been happened up to a week ago.
“We have not detected any surface cracks or sinking in the road, however, we have employed specialist geotechnical engineers who are examining the cliff face and will provide some indication of its stability.”
The results would be available in the next couple of weeks, Mr Voss said.
“It’s always a worry.
“It’s an unknown quantity and an area that we didn’t think was a problem.
“We’ll keep an eye on it.”
In the meantime, drivers are being urged to take extra care and heed any speed restrictions that could be put in place to reduce vibration from heavy vehicles.
The rock-fall comes after a slip on a nearby section of Beach Rd occurred in May, resulting in the affected section of the road being narrowed to one lane.
The council is continuing to investigate long-term solutions to Beach Rd.
