The company carrying out repairs to the A83 near the Rest and Be Thankful says its workers have been verbally abused by angry motorists during the trunk road's closure.
BEAR Scotland is working with Police Scotland to investigate the incidents, which the company says have happened after staff closed off the diversionary route – known as the Old Military Road (OMR) for safety reasons.
The OMR was closed from 7.25pm on Thursday night until after midday on Friday due to heavy rain.
It will shut again from midnight tonight (Friday) for the same reason, with a safety inspection planned for around 9am on Saturday.

The trunk road itself has been closed since thousands of tonnes of debris fell from the surrounding hills on to the carriageway during torrential rain on Tuesday, August 4.
The maintenance company says geotechnical specialists carried out assessments of debris movements in the channels above the A83 before deciding the OMR was safe to reopen on Friday afternoon.
Eddie Ross, BEAR Scotland’s north west representative, said: “We reopened the OMR this afternoon around 12.20pm following a successful safety assessment by our geotechnical team after last night’s heavy rain.
“With more heavy rain forecast we have to close the OMR from 12 midnight tonight and will carry out a safety assessment around 9am tomorrow to consider if we can reopen.

“Whilst we appreciate the frustration this can cause, safety has to come first and we need to make sure that we keep all road users safe at all times.
"We’ll continue to review the weather forecast and situation at the Rest on a daily basis to consider if it is safe to reopen.
"Hopefully the later closure time tonight will help to accommodate the majority of travellers.
“We’ve also had reports of our teams receiving verbal abuse and threats from some motorists at the road closure points on the A83.
"This abuse will not be tolerated and we are already working closely with Police Scotland to investigate these incidences.
“Please respect our workforce who are only doing their job and working to keep all road users safe.
“In the meantime, Argyll remains open for business and we thank the local community and road users for their patience while we do everything we can to repair the A83 and safely reopen it as soon as we can.”
