The B8022 is a rather curious road, starting and finishing on the B825 and taking a somewhat circuitous route through Slamannan. The route is 4½ miles long, although from end to end on the B825 is only about half that. The road was originally unclassified but had gained its number by 1932.
Starting, therefore, in High Limerigg, the road heads north through Low Limerigg, before winding a little to the east through farmland. Houses are dotted along the roadside, giving a semi-urban feel to the road, which is enhanced as it passes through Binniehill and into Slamannan itself. In the village, the road curves round to the left, into the High Street and becomes the B803. However, the B8022 turns east at a TOTSO onto Avonbridge road before the B803 turns north, also at a TOTSO, onto Main Street, and so it is unclear which number the short link between the junctions carries.
The junction with Avonbridge Road is signed merely to Avonbridge, giving no indication that it is a classified route, but the road remains a decent S2 as it heads east. It is bendier than before, with some sharp right-angle turns as it winds between fields. There are fewee houses too, giving it a much more rural feel as it runs between high hedges with occasional breaks for gates. There is a cluster of houses at Crossburn, but this is the only place even approaching a village on this section of the road. After a few more sharp turns, the road comes to an end at a crossroads at Babbithill, where neither of the road numbers are signed, although this is the B825 once more, with an unclassified road straight ahead.
