The A28 is a trunk road in southern England. It runs south-west from the seaside resort of Margate in Kent via Westgate and Birchington, reaching open countryside at Sarre. The road continues via Upstreet and Hersden to Sturry, and on to the cathedral city of Canterbury. It forms part of Canterbury's ring road before leaving via Wincheap and Thanington Without, where a sliproad linking to the A2 was completed in 2011, and passing between the North Downs via Chartham, Chilham, Godmersham and Bilting.
