The B9115 is a short road, mostly in central Banffshire. It was originally unclassified but had gained its number by 1932.
The road starts on the B9014 on the eastern edge of Drummuir and heads east. The road is narrow from the offset as it climbs across the fields and passes a few scattered buildings. After running over the brow of the hill we start to descend gradually into the valley of the Burn of Davidston. After crossing the burn (which is culverted so may be missed) we run for a minute or so through a finger of Aberdeenshire. The road then continues ahead out of the valley and soon ends at a T-junction on the A96.
