|Route outline (key)|
The road commences at a junction with the A8014 in the Kilbowie area of Clydebank. It then travels in an easterly direction, with just two bends along the way, through the Drumry area of town along Drumry Road before terminating at a roundabout junction with the A82.
It is unclear exactly when this route gained its number. The 10-mile maps never show it, despite indicating some of the other short urban roads, but the 1939 edition shows the B8056 in Wester Ross, suggesting that the B8055 number was also in use at the time. Larger-scale maps do show the road so it seems likely that the number has only ever applied to this route, and that it was simply too short / insignificant to be marked on some maps. Curiously, Google currently and incorrectly mark the road as the B8050.
