|Route outline (key)|
The B859 seems to be primarily identified from the 1946 10-mile sheet, which clearly marks the B859 as a loop to the south of the A834 of the time; however, it is difficult to be certain whether the A834 has changed course since that time.
Further comparison of various sheets identifies that at the time the A9 followed High Street and Station Road, and it seems possible that the B859 was therefore Hill Street and Greenhill Street. Whilst this does not exactly tally with the 1946 map, allowance has to be made for the small-scale. This extremely short route is marked as unclassified by the one-inch sheet of a decade later. Greenhill Street is now part of the A862, which has taken over the A9 through town.
