|Route outline (key)|
The B4021 was a T-shaped B-road in Rickmansworth town centre. It was formed when the A412 and A404 were taken out of town following construction of the relief road and the B4021 took on the section vacated. The road was short-lived and is now unclassified.
The road started where the Ebury Roundabout is now, where the A412 turned off its old route. The B4021 headed east from here along the High Street, ending where the A404 came in from the right along Church Street and took on the road ahead.
Two thirds of the way along the High Street the B4021 had a spur where Station Road headed north. It passed the station before returning to the A412 Rectory Road.
