The A40 is a major trunk road connecting London to Goodwick (Fishguard), Wales, and officially called The London to Fishguard Trunk Road (A40) in all legal documents and Acts. It is long. It is one of the few remaining of the "old" trunk routes not to have been superseded by a direct motorway link, though some parts, such as the southern section from London to Oxford are now better served by the M40. Part of the A40 forms a section of the unsigned Euroroute E30, which the former Welsh Assembly Government referred to as "one of the lowest standard sections of the Trans European Road Network in the United Kingdom"〔(Welsh Assembly Government )〕 ==History== The original (1923) route of the A40 was the City of London to Fishguard. The road still begins and ends in the same places, but a number of changes have been made to its route.〔() Road to Nowhere: A40 Ross-on-Wye to Abergavenny〕 The first change dates from 1935, between Ross-on-Wye and Abergavenny. The original route of the A40 was via Skenfrith; this road was renumbered the B4521. The A40 was rerouted via Raglan; between Ross and Raglan it replaced part of the A48, between Raglan and Llanvihangel-nigh-Usk it replaced the B4234, and between Llanvihangel and Abergavenny it replaced part of the A471. Subsequently, the A40 was rerouted within west London. Western Avenue dates from the 1930s, but was originally opened as the A403. After the Second World War, the A40 was rerouted along part of the A219 (west of Notting Hill) and Western Avenue. The old route (via Acton, Ealing, Southall, Hayes, Hillingdon and Uxbridge) was renumbered the A4020. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「A40 road」の詳細全文を読む スポンサード リンク
