The Rest and Be Thankful pass on the A83 in Argyll was re-opened today after a dangerous boulder was blown up.
The main Glasgow-Kintyre road had been shut since last week after a landslide left the 150-tonne rock threatening to fall.
The all-clear was given this morning after a safety inspection following yesterday’s explosion to break up the 4m-long boulder.
The operation broke the rock into pieces, which have been secured on the steep hillside.
The road re-opened just after 11am, but one lane remains closed so engineers can repair fencing designed to prevent landslide debris hitting the carriageway.
Eddie Ross, a spokesman for road maintenance firm BEAR Scotland said: “The A83 has now reopened after teams worked hard in challenging conditions to stabilise the rock above the road.
“We thank motorists for their patience whilst we did everything to make the situation safe and get the road opened as quickly as possible.”
Traffic has been using an emergency diversion route parallel to the A83, but the single-track road has only been open in daylight for safety.
Drivers have faced detours of up to 60 miles at other times.
