Next Manawatū Gorge rock fall could be 170 times larger than two previous slips
The Manawatū Gorge could experience a rock fall 170 times larger than the two slips that caused the state highway to close in April.
The NZ Transport Agency expects as much as 630,000 cubic metres to drop at Kerry's wall, near the Ashhurst end, which has prompted Horizons Regional Council to install webcam monitoring.
In July, the agency announced the key route, which connects Manawatū and Hawke's Bay, would close indefinitely after the 3500cum falls.
