THE Oxley Highway between Forbes River and Clay roads will remain closed until further notice because of landslips.
More than 100 new landslips have been detected on this section of the highway since heavy rainfall over the past week.
Engineers are urgently assessing damage and planning clean-up operations and long-term repairs.
Transport for NSW (TfNSW) said the clean-up of the highway will be carried out as soon as it is safe to do so.
With a substantial amount of mud to move and damage to the road, a firm re-opening date cannot be determined.
TfNSW said it will keep the community informed as more details become available.
Motorists are advised to use the Gwydir Highway, Waterfall Way or Bruxner Highway for travel between the Tablelands and the coast.
Lane and speed restrictions are in place along sections of Waterfall Way, which were also damaged during the extreme weather.
Operators of oversize and/or overmass vehicles should plan their route using the NHVR Route Planner to ensure travel on approved roads.
