The Alpine Way should be partially reopened by the end of the week, with work to remove debris caused by a recent rock fall on schedule for completion.
Roads and Maritime Services closed the Alpine Way on July 22 between two kilometres west of Thredbo to Khancoban while work to stabilise the slope and remove debris was carried out.
RMS expects to open one lane of traffic by Friday, August 2, under alternating traffic conditions with the road expected to fully reopen by the end of September once new fencing is installed.
The rock fall caused debris, including rock and soil, to damage the fence and fall across the road, requiring a total road closure of about 50km of the road since last Monday.
About 3000 cubic metres of debris was removed by workers late last week and during the weekend.
RMS and council are working together to get the road partially opened to motorists as soon as possible.
Motorists are advised the Alpine Way between Jindabyne and Thredbo Village remains open.
Motorists intending to travel on the Alpine Way between Khancoban and Thredbo near the National Parks and Wildlife Gate at Thredbo will continue to be detoured via the Snowy Mountains Highway via Tumut, Tumbarumba and on to Khancoban until the road reopens.
The detour is expected to add about three and a half hours to the journey, so motorists are advised to delay non-essential travel.
Another alternate travel route between Khancoban and Thredbo is via Elliott Way from Mount Selwyn to Tooma.
Traffic control measures and electronic signs are in place at Khancoban, Jindabyne and Tumbarumba to direct motorists.
Motorists are advised to drive with caution, obey all signs and the direction of traffic controllers and allow extra travel time.
