The Rest and Be Thankful has reopened following a safety inspection.
Traffic lights are in place to control the flow of traffic, but the stretch of the A83 will close again at 5pm as heavy rain is forecast.
Bear Scotland is keeping the route under “careful review” following almost a week of heavy rain in the area. Inspections have been regularly carried out and teams are continuing with mitigation work on the hillside about the A83.
About five inches of rain has fallen, meaning teams are on high alert.
The Old Military Road diversion will be in place overnight once more, and a convoy will be in place.
About five inches of rain has fallen, meaning teams are on high alert.
The road has been closed repeatedly in recent weeks, following a significant landslip in August – when huge boulders and thousands of tonnes of debris crashed down the hillside.
Eddie Ross, Bear Scotland’s north-west representative, said: “The A83 reopened under traffic light control at around 8am this morning following a safety inspection by our geotechnical teams on site.
“We’re putting road user safety first and the route will be kept under careful review with teams continuing to monitor the conditions in the area as well as the hillside above the road. Given the level of rainfall experienced over the past week, we have retained the OMR local diversion in a state of readiness.
“It is difficult for us to monitor the hillside and any sudden changes in conditions during the hours of darkness, and given the further rain forecast, we continue to put the safety of motorists first and will close the A83 as a precaution overnight and utilise the OMR local diversion instead. We are continuing to install mitigation measures at the A83 and we will endeavour to do all we can to keep disruption to a minimum. As ever we thank road users and the local community for their patience while we continue this work at the Rest.”
