|Route outline (key)|
One of Britain's most northerly classified roads, the two-mile-long B9086 on the isle of Unst runs to within four miles of Muckle Flugga, the nearly-northernmost point of the United Kingdom (the smaller Shetland islet of Out Stack is actually a little further north).
The route starts at the UK's most northerly classified road junction at Haroldswick, where the B9087 turns off the A968, which itself morphs into the B9086. The road heads northwest across the plain before crossing some low hills and going through Burrafirth. After crossing the outflow of the Loch of Cliff the road ends at a road/track junction with an unclassified road.
There appears to be some local confusion about this road, however, as signs at its starting point near Haroldswick suggest that the B9087 heads in both directions. This is believed to be a signing error, as maps show the B9086 as extant, and at the very next junction it is correctly signed. Furthermore, some maps claim (in equally unlikely fashion) that the coast road through Haroldwick is a disconnected spur of the B9086 despite its being the original route of the B9087.
