 As the Snodland Bypass ends the road rejoins its historic route (albeit on very recent much enlarged roads) for a short stretch on Malling Road which becomes Castle Way as it approaches Leybourne.At this point, where the route crosses the M20, the route again diverts onto a new bypass, this time the Leybourne Bypass, opened November 2006, which then passes under the A20 (a road that it used to junction) and then joins the West Malling Bypass.Passing Manor Park Country Park to the west and the roundabout at the northern entrance to Kings Hill, the road becomes Ashton Way before meeting the Malling Road at the southern tip of West Malling and proceeding through Mereworth.
