Road and hillside inspections will be carried out this morning at the Rest and Be Thankful site in Argyll, which has been badly affected by landslides.
Experts will assess the timescales for opening the Old Military Road emergency diversion route which runs alongside the A83.
This will bring an end to the 60-mile diversion via Dalmally and Crianlarich which is causing misery to October holiday motorists.

When Storm Callum abated, the clear-up operation started atthe weekend. Removing debris from the road and reinstating drainage continued yesterday in improved weather conditions.
Geotechnical assessments were also taking place at several areas of potential concern including a number of boulders.
Multi-disciplinary teams, including rope access personnel, geotechnical engineers, specialist machinery operators, BEAR Scotland staff and heavy plant contractors, worked through challenging conditions to prepare for the reopening.
Further patrols are operating on a 24-7 basis on the diversion route via the A85 Oban to Perth road at Dalmally to help assist road users and address any issues to help keep Argyll open for business.
Eddie Ross, BEAR Scotland’s north west manager said: “Now that Storm Callum has passed, our geotechnical experts can get a closer look and consider what needs to be done prior to the Old Military Road and ultimately the A83 re-opening.
“We’re aware of the impact this is having on the busy weekend and holiday traffic and businesses.
“Our additional safety patrol on the diversion route via A85 Dalmally proved to be useful yesterday assisting motorists and dealing with issues caused by the storm. This will continue today and until the route re-opens.
“As ever, we thank the local community and road users for their patience and assure them we’re doing everything we can to address the multiple landslips at the Rest and Be Thankful as quickly and safely as we can.
“We remind road users that Argyll remains open for business, and rest assured we’re doing everything possible to get the Old Military Road and A83 open as soon as it is safe to do so.”
Meanwhile the Lochavullin car park in Oban, which was flooded by last week’s storms, remained closed over the weekend.
Argyll and Bute Council said it would asses the situation today.
A period of calmer weather is expected, with no more weather warnings in place from the Met Office for this week so far.
