A GIANT boulder which forced the closure of a main road is set to be blown up this morning.
The 150 tonne rock was left 175m above the carriageway on the A83 at the Rest and Be Thankful, following a landslip during Storm Frank.
Roads operator Bear Scotland was forced to shut the thoroughfare last Wednesday after 200-300 tonnes of debris fell onto the carriageway.
Engineers will use explosives on the boulder this morning, breaking it up into smaller fragments so it can be removed more easily.
A spokeswoman said: "The process involves drilling a series of holes to weaken the boulder.
"A small explosive device is then detonated to break the rock into smaller manageable pieces.
"Netting will be placed over the boulder to reduce the scatter of debris and any larger pieces will then be further broken down and stabilised on the hillside."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
