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.
The A28 plunges back into suburbia at Kennington, a suburb of Ashford, but skirts around the town centre on a section of dual carriageway. In 1982, this section was named Simone Weil Avenue, in honour of the French philosopher and mystic. Bypassing Great Chart, the road undulates around the Kentish Weald via Bethersden and High Halden, to the market town of Tenterden.
The A28 continues via Rolvenden and Newenden before crossing a narrow bridge over the River Rother and entering East Sussex via Northiam, beyond which the road becomes very winding. After Brede there is a steep descent to bridge the river of the same name. Next is Westfield, just before the road climbs to terminate at its junction with the A21 just north of Hastings.
Work has continued to improve the A28 into the 21st century. For example, in 2011 a new slip road was completed to connect the road to the A2 in Canterbury.
