Drivers have been forced to divert almost 60 miles to avoid part of the A83 blocked off by a major landslide on Tuesday.,

Clear-up operations are currently underway on the A83 at Rest and Be Thankful and the Old Military Road after heavy rainfall caused multiple lanslips.

Crews have confirmed large, car-sized boulders have been brought down the hillside onto the carriageway.

Approximately 1500 tonnes of debris is thought to have reached the A83, with around 2000 tonnes of material washed onto the Old Military Road.  

In total, the landslide is thought to have moved around 6,000 tonnes of debris across the hill.


Drivers are now facing a diversion of almost 60 miles to avoid the blocked path.

Up to 100mm of rainfall is estimated to have fallen across Argyll on Tuesday, which BEAR teams say created a ‘fan effect’ down multiple water channels some of which reached the roadside.

It is the second time this year that the road has been closed due to debris, with the stretch blocked in January for two days after being covered by 1300 tonnes.


Eddie Ross, BEAR Scotland’s North West representative said: “Yesterday’s heavy rain caused a large landslip high above the road which reached the A83 and OMR roadside at multiple points, bringing significant amounts of debris.

“Our teams have mobilised at both ends of the A83 at the Rest and OMR and have begun the initial clear-up of the debris.  

“Further assessments need to be completed by geotechnical specialists of the hillside and both roads to check for any further concerns, and until these checks and the clear-up is complete the A83 and OMR will remain closed.  

A standard diversion route has been implemented between Tarbet and Cairndow via the A83, A82, A85 and A819.
