Experts are assessing damage to a tourist road through the Tarkine in Tasmania's north west, caused by a major landslip.
The Western Explorer road is impassable south of Donaldson River after a 20 to 30 kilometre section collapsed in heavy rain.
It is not known when the road will re-open.
Detours have been set up, as well as signs alerting tourists at Balfour and Corinna.
Geo-technical assessments will be done over the next couple of days to work out how to carry out repairs..
The Infrastructure Department says there is also evidence of cracking in the road, which could mean a bigger problem.
Spokesman Shane Gregory says it is the least used road in the state network, but it will be repaired.
"We really need to get a team of experts there to have a look, sometimes these things are fairly easy to fix," he said.
"In other cases we actually need to dig more of the road away and create a sound base to rebuild the road on and it's possibly that that's the case.
Another landslip has closed the southbound lane at Beatties Hill on South Road at Lileah.
The road is still accessible but the speed limit's been lowered to 40 kilometres an hour.
Meanwhile Aurora Energy has restored power to 500 customers in the north.
The homes and businesses have not had electricity since early yesterday morning when strong winds blew powerlines into Pipers River, north of Launceston.
Richard Wilson from Aurora Energy says it was originally thought a helicopter would be needed to fix the lines, but receding flood waters allowed the repairs to go ahead.
"So we were able to get a rope across the river and have that tied on to the power lines and then the power lines were reconnected to new poles on either side of the river," he said.
20 customers around Lake Saint Clair are still without power after a pole fire this morning, including the Lake Saint Clair Lodge and a caravan park.
