|Route outline (key)|
Before the A9 was extended north in 1935, it was the A88 that went from Inverness to Thurso. Therefore everything north of Inverness was in the 8 zone, and so the road heading north of Dornoch to the A-road at Poles was the B868. With the A9 extension, roads to the east had to be renumbered as part of the 9 zone, so the B868 became the B9168.
Rather curiously, while the B86x routes on the Black Isle were busily being renumbered as B916x in the draft proposals for the 1935 renumberings, in Dornoch the idea was to merge the B868 into an extended B867, which would then have been wholly out of zone. Rather sensibly, this idea was discounted, and the roads subsequently became the B9167 and B9168!
