State Highway 6, from Haast to Lake Hawea, has re-opened to
single-lane traffic this afternoon after a slip saw massive
rocks fall onto the highway early this morning, closing the
road to all traffic.
The NZ Transport Agency's Senior Asset Manager West Coast
Mark Pinner said contractors would remain at the site until
dusk, continuing to clear the slip and remove as much of the
debris as possible.
" A significant number of large boulders fell on to the road
1km west of Clarke's Bluff. These are extremely large and we
are having to blast most of them to be able to remove them
from the highway.
"It is estimated 750 tonnes of rock has fallen. It will be
blasted and removed to Burke Flat."
Mr Pinner said a geotechnical expert had checked the area had
stabilised and that it was safe for motorists.
"Our contractors will be on site again at first light
tomorrow to keep working on clearing the road. Motorists are
advised to expect delays as this work progresses throughout
At this stage, the cause of the rockfall is not known.
