|Route outline (key)|
The original B854 was the hill road north from Milton, west of Drumnadrochit, to Balchraggan in Inverness-shire: the route which is now numbered A833. Apart from a few new bridges and some widening, the road appears to be little changed since 1922.
The road was almost certainly reclassified as part of the 1935 renumberings. The opening in 1934 of a new crossing of the Leven at Balloch in Dunbartonshire saw the road via the old bridge there reduced to Class II status and given the number B854. The previous use of the number A833 for another road also ended in 1935 (when the main route between Muir of Ord and Cromarty became an extension of the A832).
Mapping appears to have taken some time to catch up, however. Bartholomew mapping from 1938 still labels the road B854, while the 1939 Ordnance Survey Ten Mile map – as well as indicating the Dunbartonshire B854 – shows the Inverness-shire road with both numbers (B854 and A833)!
