"Which modem ""A"" road mainly follows the Roman road Watling Street?"
Watling Street new dual carriageway while Watling Street proper remains and forms part of the Milton Keynes grid road system. The name Watling Street is still used along the ancient road in many places, for instance in Bexleyheath in southeast London and in Canterbury, Gillingham, Strood, Gravesend, and Dartford in Kent. A major road joining the A5 in northwest London is called Watling Avenue. North of London, the name Watling Street still occurs in Hertfordshire (including St Albans), Bedfordshire, Buckinghamshire (including Milton Keynes), Northamptonshire (including Towcester), Leicestershire (Hinckley), Warwickshire (including Nuneaton and Atherstone), Staffordshire (including Cannock, Wall, Tamworth and Lichfield), Shropshire (including
Watling Street in Church Stretton along the A49), and even Gwynedd in north Wales. Dere Street, the Roman road from Cataractonium (Catterick in Yorkshire) to Corstopitum (now Corbridge, Northumberland) to the Antonine Wall, was also sometimes known as Watling Street. A third Watling Street was the Roman road from Mamucium (Manchester) to Bremetennacum (Ribchester) to Cumbria. Preston, Lancashire, preserved a Watling Street Road between Ribbleton and Fulwood, passing the Sharoe Green Hospital. Both of these may preserve a separate derivation from the Old English "wealhas" ("foreigner") or may have preserved the memory of the long Roman road while misattributing its upper stages
