The B9125 is a relatively short route in east Aberdeenshire, but forms an important connection in many routes both locally and longer distance. The road was originally unclassified but had gained its number by 1932.

Heading southwest from the B9119 in Garlogie, the first couple of miles are relatively twisty, although there are some reasonably long straights. There is typically a high amount of agricultural traffic along this section, due to the presence of a number of farms either side of the road. The route is mostly uneventful through these twists and turns, as it runs between fields and patches of woodland. A long sweeping bend leads through an old fiveways junction at Schoolhill, although the side roads have been pushed apart a little to help turning traffic. The route then dips down around a tighter double bend to cross a relatively narrow bridge over the Gormack Burn (two vehicles can pass each other without issue, but compared to the rest of the route, it feels quite tight).
Just past the bridge is a right turn into an industrial estate, which also contributes to the typically high proportion of HGVs on the road. The B9125 straightens out considerably now, for the last stretch. The long straight stetches into the distance as the B977 comes in from the right. This is a busy junction, which happens to be the end of the B9125, as the B977 TOTSOs here and continues west to Raemoir and the A980.
