IT could be six months before a dangerous landslip off the West Tamar Highway will be rectified.
The West Tamar Council was told about the slip visible from Tailrace Park last week, which was believed to have been caused by last week's heavy rainfall.
The Infrastructure Department has since erected barriers along the highway and dropped the speed limit on the section of road from 70km/h to 50km/h _ a reduction that is being heavily policed.
Heavy vehicles have been advised to travel in the right-hand lane.
West Tamar general manager Ian Pearce said the council was in discussions with the department, Hydro Tasmania and Taswater, who also own infrastructure in the affected area.
``At the moment, we're all talking to each other about how to fix it,'' he said.
``It could be about five or six months before it is all resolved.''
He said geotechnical experts had been recruited to ascertain what repairs were needed.
Mr Pearce said these repairs were hoped to be completed before any potentially damaging rainfall occurred.
He said the estimated repair costs were unknown but were believed to be substantial.
