Although it has been confirmed the Bells Line of Road was not damaged beyond repair it looks likely the major thoroughfare could remain closed for months due to the sheer magnitude of even assessing the destruction, let alone fixing it.
The road has been closed between Bell and Berambing - approximately 25 kilometres - since March 21 after torrential rainfalls caused multiple landslides around the Mount Tomah region, which impacted the road and the mountain's stability too.
The road's closure contributed to incredibly delays over the Easter long weekend as the alternative route, the Great Western Highway, descended into chaos with traffic, at times, backed up for kilometres across the Blue Mountains.

But work has begun, with Minister for Regional Transport and Roads Paul Toole saying the re-opening of the Bells Line is a priority.
"We're getting on with the job re-opening the road as quickly as we can," Mr Toole said, via one of his regular social media updates on Tuesday night.
"The closure of Bells Line contributed to significant delays on the Great Western Highway over the weekend, so we're working hard to re-open Bells Line as soon as we can to keep communities connected and to help bust traffic."
Mr Toole explained 'crews have been out in force' to assess the damage, with that job carrying dangers in itself for engineers due to the instability of the area's slope, with further threats of failure apparent.
"On top of further threats of slope failure, a ground penetrating radar has detected a number of voids underneath the road which must be addressed prior to opening the road," he said.
A full report of the ground penetrating radar was expected to become available on Wednesday for assessment by geotechnical engineers and road specialists.
The road's failure brings suggestions of a tunnel through the Blue Mountains back to the fore, with exactly that proposed between Lithgow and Katoomba as part of the NSW Government's $2.5 billion investment to upgrade the highway.
