|Route outline (key)|
In 1922, the B864 number was originally allocated to the road from Alness to the inner Dornoch Firth near Bonar Bridge, across Struie Hill, thus allowing a shorter, albeit much hillier, route than the main A88 which it met at both ends.
The road became part of an extended A836 sometime before 1932, and the B864 number was allocated to its current route north of Lairg around the same time. As such the B864 was one of the few B86x roads not affected by the A9 northward extension in 1935. Perhaps ironically, therefore, the ex-B864 is now the out-of-zone B9176, with the road having been downgraded following construction of the Dornoch Firth Bridge on the A9 in 1991.
