Sorry if this is old news, but I was completely unaware of it until this evening; it could affect the plans quite a few people.
I just received an email saying that
"An application has been made for a Temporary Traffic Order (Temporary Road Closure) between Monday 28th January 2013 and Friday 5th April 2013 for the temporary closure of the B8005 and the C1153. The road is being closed so that bridge and road repairs can be undertaken."
This is the road along the North side of Loch Arkaig, which is one of the normal ways of approaching the Rough Bounds of Knoydart and nearby areas. It looks like the closure is the whole stretch West of Clunes, though there may be some arrangements possible for partial access some of the time; the start date doesn't seem to be set in stone yet.
I haven't posted the whole email as it doesn't give explicit permission to do so; others may have more details.
