 Branching off the A217 on at Burgh Heath, at the north of a plateau of the North Downs at 178m OD, the road descends northwest passing the large village of "Great Burgh" or "Epsom Downs" as a single carriageway primary road, through traffic-lit crossroad junctions with the suburban B2221..The B2221 branches off and after there is a crossroads for Yew Tree Bottom Road; it crosses the Sutton and Mole Valley Epsom Downs branch line immediately before exiting the borough.The road enters the Borough of Epsom and Ewell just before A2022 heads west into Epsom at a roundabout.
