The Rest and Be Thankful will close at 8pm this evening (Tuesday, July 27) due to a forecast of heavy rain, with a convoy system in operation from noon today.
The Old Military Road (OMR) local diversion route to the A83 at the Rest and Be Thankful is to be used for all traffic.
An assessment will be made at 12pm tomorrow (Wednesday 28 July) as to whether the road is safe to reopen.
The OMR, a single-track road which runs parallel to the A83 through the centre of Glen Croe, will be used overnight with all traffic being convoyed along the route throughout the night as a safety precaution due to forecast heavy rain throughout the area.
Met Office yellow warnings have been issued for thunderstorms and rain across most of mainland Scotland today until 6am on Thursday morning. Heavy showers are expected to impact Argyll throughout the evening and Wednesday morning.
Eddie Ross, BEAR Scotland’s North West representative said: “We’ve been assessing the weather forecast over the next few days and have taken the decision along with Transport Scotland to direct all traffic to use the Old Military Road from 8pm tonight as a safety precaution.
“Tonight’s forecast has indicated heavy rain throughout the night which is difficult to monitor the impact of on the hillside during the hours of darkness, with further heavy rain expected tomorrow morning. We’re continuing to put road user safety first and will therefore reinstate the OMR from 8pm as a precaution.
“We’ll assess the area tomorrow lunchtime once the weather front has passed and determine if it is safe to reopen the A83 as before.
“Teams are continuing to pay close attention to the weather conditions in the area and are monitoring the hillside for any changes.
“As ever, we thank all road users and the local community for their patience in advance while we continue with our work to address the Rest and Be Thankful.”
