Became a portion of an extended A192 after World War II. A roads in Great Britain In Great Britain , there is a numbering scheme used to classify and identify all roads. Each road
122-541: A new roundabout just west of Llain Cottage. The Secretary of State for Wales was asked a written question by Rhodri Morgan about adding a second carriageway to the Whitland bypass scheme, to which John Redwood replied "There are no proposals to add a second carriageway to the Whitland bypass. The design capacity of a single carriageway two-lane highway is more than adequate to cater with the anticipated traffic flows for
183-500: A point on the trunk road approximately 622 metres south of the centreline of the junction of the A40 trunk road with the C3059 road to Spittal and extending in a generally northerly direction to a point approximately 112 metres south of the junction of the trunk road with the C3059 road to Spittal. This resulted in the road being rerouted through pasture to the east of the original road, taking
244-436: A right hand bend about 160 metres (520 ft) south of The Old Mill, taking a 5.5% gradient, and rejoining the original road 210 metres (690 ft) north of The Kell. The original road has subsequently been converted to an access road for The Old Mill, Beavers Lodge and The Kell, accessing the new road at The Old Mill. Fishguard Bypass The Fishguard Bypass was planned to provide a more direct route with greater capacity to
305-574: Is "not advised". Exceptions to this are known in the forms of numbers on signs and past use of prefixes H and V on signs in Milton Keynes where main roads have a regular grid system . These designations are used when planning officers deal with certain planning applications , including the creation of a new vehicular access onto a highway. The letter Q is used for many important unclassified roads in Fife . In London, Cycleways are using
366-662: Is a trunk road which runs between London and Goodwick ( Fishguard ), Wales , and officially called The London to Fishguard Trunk Road (A40) in all legal documents and Acts. Much of its length within England has been superseded by motorways, such as the M40, and has lost its trunk road status, though it retains it west of Gloucester, including its length within Wales. It is approximately 260 miles (420 km) long. The eastern section from Denham, Buckinghamshire to Wheatley, Oxfordshire
427-571: Is better served by the M40 and its former function of linking London with Cheltenham and Gloucester has been taken by the M4, A419 and A417 via Swindon. The A40 1923 route was from 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. The first change dates from 1935, between Ross-on-Wye and Abergavenny . The original route of
488-599: Is between Zones 1 and 2, where the River Thames defines the boundary so that all of Kent is in Zone 2. The first digit in the number of any road should be the number of the furthest-anticlockwise zone entered by that road. For example, the A38 road , a trunk road running from Bodmin to Mansfield starts in Zone 3, and is therefore numbered with an A3x number, even though it passes through Zones 4 and 5 to end in Zone 6. Additionally,
549-634: Is controlled by the Welsh Government (formerly 'Welsh Assembly Government'), which describes it as "one of the lowest standard sections of the Trans European Road Network in the United Kingdom". St Clears to Haverfordwest dualling There were plans in 2002 for a major improvement of the 23-mile stretch between St Clears and Haverfordwest which included upgrading to a dual carriageway; described as an extension of
610-495: Is denoted by the colour of the sign border and direction arrow, and can be summarised as follows: Roads and lanes with yet lower traffic densities are designated as unclassified roads commonly using C , D and U prefixes but, while these are numbered, in general this is done for use by the local authorities who are responsible for maintaining them and the non-unique numbering is in a local series which usually does not appear on road signs; use of local numbers on signs in England
671-452: Is given a single letter (representing a category) and a subsequent number (between one and four digits). Though this scheme was introduced merely to simplify funding allocations, it soon became used on maps and as a method of navigation. There are two sub-schemes in use: one for motorways , and another for non-motorway roads. While some of Great Britain's major roads form part of the international E-road network , no E-routes are signposted in

#1732771808191732-632: Is located less than 1 mile (1.6 km) east of Trecastle . In Llandovery the road crosses the Heart of Wales railway and the River Tywi ; the road, railway and river then run parallel until Llandeilo , where the National Park ends and the railway turns south. The A40 continues west along the Tywi valley to Carmarthen where as a dual carriageway it forms the eastern bypass, meeting the terminus of
793-534: Is proposed that a roundabout would be created just north of Glenfield Farm, where the straight section from St Clears ends at Bethel Chapel, and then take a new route north-west of the town of Llanddewi Velfrey, south-west over Pentroydin Fawr and Penttroydin Fech farms with cattle underpasses, a new underpass beneath the existing Llanddewi Velfrey to Llanfallteg road, before going over the original A40 at Ffynnon Wood . To
854-592: The A13 (London to Shoeburyness); the next radial is the A2 , followed by the A20 (London to Dover), and so on. These roads have been numbered either outwards from or clockwise around their respective hubs, depending on their alignment. The system continues to three and four digit numbers which further split and criss-cross the radials. Lower numbers originate closer to London than higher numbered ones. As roads have been improved since
915-722: The A470 north, which is the main north–south road through mid-Wales. Continuing as a dual carriageway, the A40 and A470 concurrent bypass Brecon to the south, crossing the River Usk here. At the western end of the bypass is a further junction with the A470 south. Beyond this point the A40 continues as a single carriageway, now south of the River Usk, and roughly follows the northern edge of the Brecon Beacons National Park. A height of 820 feet (250 m) above sea level
976-629: The A5 Edgware Road as far as the Marylebone Flyover to become Westway (classified A40(M) as an elevated motorway) then meets Western Avenue . For the greater part, this section is six lanes, otherwise four lanes. With two exceptions, Western Avenue forms a grade-separated motorway standard dual-carriageway between Paddington and the M40 motorway . The two at-grade intersections are Gypsy Corner and Savoy Circus; both of which are traffic light controlled. At Denham Roundabout ,
1037-1146: The C prefix and marked using pale green signs. There are also some CS prefixes for Cycle Superhighways, marked using magenta signs, but these are being phased out. Despite numerous large roads in Great Britain being part of the International E-road network , no road that forms part of this network is signposted as such and only the road's national designation is shown. The same is true in Northern Ireland.

The Preston Bypass , the UK's first motorway section, should have been numbered A6(M) under the scheme decided upon, but it was decided to keep the number M6 as had already been applied. The first full-length motorway in
1159-594: The M5 motorway . In February 2015, the Witney Oxford Transport Group proposed the reopening of Yarnton railway station as an alternative to improvements to the A40 road proposed by Oxfordshire County Council . The A40 is the Gloucester bypass, most of which is dual carriageway. The junction with the A48 to Chepstow is at Highnam. For the remainder of Gloucestershire, and a part of Herefordshire ,
1220-400: The A road designation, for example A3(M) , A329(M) , A38(M) , A48(M) and A627(M) . B roads are numbered distributor roads , which have lower traffic densities than the main trunk roads, or A roads. This classification has nothing to do with the width or quality of the physical road, and B roads can range from dual carriageways to single track roads with passing places. B roads follow
1281-712: The A1 in Newcastle upon Tyne has moved twice. Originally along the Great North Road, it then moved to the Tyne Tunnel , causing some of the roads in Zone 1 to lie in Zone 6. The designated A1 later moved to the western bypass around the city, and roads between the two found themselves back in Zone 1. For the most part the roads affected retained their original numbers throughout. Elsewhere when single-digit roads were bypassed, roads were often re-numbered in keeping with
SECTION 20
#17327718081911342-722: The A40 becomes a busy dual carriageway, carrying traffic from the M40 to Oxford and beyond. The road forms the northern section of the Oxford Ring Road , crossing the A44 and the A34 . In Oxford, it passes the Thornhill Park and Ride, where the OxfordTube, The Airline to Heathrow & Gatwick, & Oxford Park and Ride buses stop. The A40 passes under the A34 , reverting to single carriageway for 10 miles (16 km) until
1403-609: The A40 was via Skenfrith , avoiding Monmouth; 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
1464-591: The A465, M4 and A48. The A40 becomes single carriageway and continues through Abergavenny, following the north side of the Usk valley through the eastern part of the Brecon Beacons National Park until Brecon . At Bwlch between Abergavenny and Brecon, the A40 is 660 feet (200 m) above sea level. The A40 is dualled for over 1.5 miles (2.4 km) as it approaches a junction east of Brecon with
1525-487: The A48 at Pensarn. Here the A40 returns to being a primary route westwards. At Carmarthen the A40 crosses the River Tywi twice with two 90-degree junctions and continues on 10 miles (16 km) of dual carriageway as far as St. Clears , where the dual carriageway ends at the junction with the A477 trunk road . Now the A40 is a mixture of 2 or 3 lane single-carriageway to Haverfordwest and Fishguard . This section of road
1586-631: The Board's senior engineers, to devise a classification system and then assign numbers to the highways for identification purposes. The work was interrupted by the First World War . It did not resume until the Ministry of Transport was formed in 1919 and given authority to classify highways and to allocate funding for road maintenance, authority for which was granted by section 17 (2) of the Ministry of Transport Act 1919 . A classification system
1647-537: The Ministry direct control of major routes and a new classification system was created to identify these routes. Originally, those numbers beginning in T were to be made public, but that was eventually deemed unnecessary. With the introduction of motorways in the late 1950s, a new classification of "M" was introduced. In many cases the motorways duplicated existing stretches of A road, which therefore lost much of their significance and were in some cases renumbered. There
1708-478: The Port of Fishguard at Goodwick avoiding the town centre of Fishguard. It was constructed during the late 1990s and opened in 2000. It takes the form of a three-lane carriageway on an approx. 10% gradient around the western edge of Fishguard. It runs from its highest point at Rafael roundabout 1 km south of Fishguard town in a generally northerly direction to its lowest point at Windy Hall roundabout where it rejoins
1769-534: The UK was the M1 motorway . Shorter motorways typically take their numbers from a parent motorway in contravention of the zone system, explaining the apparently anomalous numbers of the M48 and M49 motorways as spurs of the M4, and M271 and M275 motorways as those of the M27 . This numbering system was devised in 1958–59 by the then Ministry of Transport and Civil Aviation , and applied only in England and Wales. It
1830-559: The United Kingdom in the Isle of Man , Jersey and British Overseas Territories . Work on classification began in 1913. The Road Board had been established in 1909 to administer Vehicle Excise Duty - money raised by taxation to pay for new road construction and for repair of damage done to existing roads by the growing number of motorists. As the Board needed to work out which roads should be funded, upgraded or replaced, its secretary, William Rees Jeffreys , appointed Henry Maybury , one of
1891-638: The United Kingdom. Due to changes in local road designation, in some cases roads are numbered out of zone. There are also instances where two unrelated roads have been given exactly the same number; for example, the Leicester Ring Road and a road in Cumbria are both designated A594. This scheme applies only to England , Scotland and Wales ; a separate system using similar conventions is used in Northern Ireland , as well as outside

1952-407: The aim of better targeting road funding. Some A roads are designated trunk roads , which implies that central government rather than local government has responsibility for them. A more recent classification is that of primary routes , the category of recommended routes for long-distance traffic. Primary routes include both trunk and non-trunk roads. Some sections of A roads have been improved to
2013-490: The assembly committee has come to the right decision". Whitland Bypass The last improvement to the A40 on this section prior to the Welsh Assembly Government having the devolved responsibility for this road was a 4.1 kilometres (2.5 mi) £8 million bypass around Whitland . Constructed in 1994, the road started east of Black Bridge on the original A40, then running north of the town before to
2074-416: The basis for the numbering of the A road network, they are no longer necessarily major roads, having been bypassed by motorways or other changes to the road network. These radials are supplemented by two-digit codes which are routes that may be slightly less important, but may still be classified as trunk routes, although many of these routes have lost a lot of their significance due to motorway bypasses, or
2135-604: The blue route, and only 20% preferred the red route. 54% felt the section from Ffynnon Wood and Penblewin Roundabout needed improvement, with both orange and purple routes preferred by 42% of the respondents. Welsh Water/Dwr Cymru expressed concerns with the red route affecting water mains and sewers, and Henllanfallteg Community Council felt the red route would not improve the quality of life in Llanddewi Velfrey. Pembrokeshire County Council expressed concerns that
2196-522: The dual carriageway just east of Witney with a grade-separated junction. The dual carriageway finishes at a roundabout. For the rest of Oxfordshire and Gloucestershire until Cheltenham , other than for a few short stretches, the road is single carriageway. A height of 820 feet (250 m) above sea level is located 3 miles (4.8 km) west of the A429 junction. Before Andoversford the A436 breaks off to
2257-576: The existing route including bypasses around Robeston Wathen and Llanddewi Velfrey using a three-lane option. This was welcomed by the Friends of the Earth , saying "The dual carriageway on the A40 would increase traffic levels, increase the emission of greenhouse gases, it would be harmful for the environment, it would be hugely expensive. That money would be better spent on improving public transport, on health, on education, there's no need for it. We think
2318-466: The foreseeable future." Llanddewi Velfrey Bypass A new bypass has been granted approval by the Welsh Assembly Government at Llanddewi Velfrey in Pembrokeshire . The scheme would improve the A40 between Llanddewi Velfrey and Penblewin , to the west of St Clears and meet the aim of the targeted investment in infrastructure along the east–west road corridor in south Wales. From the east, it
2379-463: The improvements. The following Welsh elections saw both constituencies change the party of majority. The political party at the centre of the row instead directed the project deferment to damning environmental statements by Friends of the Earth Cymru. The scheme was officially scrapped in 2008 after a Welsh Assembly committee decided to abandon the proposals. Instead, it recommended upgrades to
2440-450: The latter. Shortly after this, the numbers started to appear in road atlases and on signs on the roads themselves, making them a tool for motorists in addition to their use for determining funding. The numbers of the roads changed quite frequently during the early years of the system, because it was a period of rapid expansion of the network and some numbered routes did not follow the most usual routes taken. The Trunk Roads Act 1936 gave
2501-526: The national motorway network to the West Wales coast by virtue of the route from the M4 motorway being entirely dual carriageway. The £60 million scheme was subject to a European Environmental Assessment. Within a couple of years, the project appeared to be dying a very quiet death, causing local newspapers to report it being an election stunt for the two marginal constituencies that would best benefit from

2562-478: The new motorway would take the name of the old A road rather than having its own number. The most notable example of that is the A1(M) . In England and Wales the road numbering system for all-purpose (i.e. non-motorway) roads is based on a radial pattern centred on London . In Scotland the same scheme is centred on Edinburgh . In both cases the main single-digit roads normally define the zone boundaries. The exception
2623-745: The only tunnels on the A40. Near Raglan , the A40 has a grade separated junction with the A449 . The A40 continues as a dual carriageway to Abergavenny . At Abergavenny is the A40 junction with the Heads of the Valleys road, ( A465 ) and the A4042. Now the A465 becomes the primary route between the Midlands to the South Wales Valleys and Swansea; there is a dual-carriageway route to Carmarthen via
2684-554: The original budget did not include either, as well as additional statutory procedures, additional works following some design standards, and the increase in VAT. The Kell The Kell is located on a section of the A40 that forms a north–south corridor between Fishguard , 17 kilometres (11 mi) to the north and Haverfordwest , 7.5 kilometres (4.7 mi) to the south, close to Treffgarne and Spittal . The improvement saw about 0.48 kilometres (0.30 mi) of new trunk road commencing at
2745-481: The original zone boundaries. A few roads are anomalously numbered . Motorways first came to Britain over three decades after the advent of the A-road numbering event, and as a result required a new numbering system. They were given an M prefix, and in England and Wales a numbering system of their own not coterminous with that of the A-road network, though based on the same principle of zones. Running clockwise from
2806-639: The road is single carriageway until Ross-on-Wye . There it connects with the M50 motorway , and forms part of the high quality dual carriageway between South Wales and the English Midlands . From Ross-on-Wye to Monmouth the road follows the Wye Valley , an Area of Outstanding Natural Beauty , crossing the Wales–England border a mile east of Monmouth. Just west of Monmouth are twin tunnels; these are
2867-569: The route planned was a single carriageway, and that within seven years, a dual carriageway would be required. Robeston Wathen Bypass A new bypass has been constructed between Penblewin and Slebech Park making the road straighter and with a '2+1' road layout to help improve overtaking opportunities. Starting to the west of Toch Lane (approx. 2 kilometres (1.2 mi) east of Slebech ), the route travels eastwards for 4.6 kilometres (2.9 mi), passing 200 metres (660 ft) south of Robeston Wathen , and ending 0.5 kilometres (0.31 mi) east of
2928-496: The same numbering scheme as A roads, but almost always have 3- and 4-digit designations. Many 3-digit B roads outside the London area are former A roads which have been downgraded owing to new road construction; others may link smaller settlements to A roads. B roads in the county of Devon have further sub-classifications according to their accessibility. This is due to the rural nature of Devon's topology making some roads unsuitable for certain types of vehicle. The classification
2989-405: The same standard as motorways, but do not completely replace the existing road; they form a higher standard part of the route for those which are not excluded. These sections retain the same number but are suffixed with (M), for example the A1(M) and A404(M) . There have been occasions where this designation has been used to indicate motorway bypasses of an existing road, but the original retains
3050-406: The scheme commenced, some roads with 3 or 4 digit numbers have increased in significance, for example the A127 , A1079 and A414 . New routes have also been allocated 3 or 4 digit numbers, for example the Edinburgh City Bypass is the A720 . The Major Road Network is a proposed classification of major local-authority controlled A roads that the government committed to implementing in 2017, with
3111-413: The short M85 became part of the M90 . In England and Wales, the six single-digit numbers reflect the traditionally most important radial routes coming out of London. Starting with the A1 which heads due north, numbers were allocated sequentially in a clockwise direction, thus: Similarly, in Scotland, important roads radiating from Edinburgh have single-digit numbers, thus: While these routes remain

#17327718081913172-407: The six lane Western Avenue flows into the M40 . The A40 branches off the Denham roundabout to run as a dual carriageway. After the junction with the A413 , the A40 follows the same route as the M40 as a single carriageway, passing through Beaconsfield and High Wycombe . Beyond Stokenchurch the road is much quieter; when meeting the B4009 and A329 those roads have priority. Approaching Oxford ,
3233-420: The upgrading of other A-roads (such as the A38 (M) ). These routes are not all centred on London, but as far as possible follow the general principle that their number locates them radially clockwise from the associated single digit route. For example, the A10 (London to King's Lynn) is the first main route clockwise from the A1, the A11 (London to Norwich) is the next, then the A12 (London to Lowestoft) and
3294-429: The village, just west of Flimstone Lane. Construction started on the route in February 2009, with the works completed and the new road opening 1 March 2011. The road was built by Costain . The scheme was nearly £14 million over the initial budget of £27.6 million, eventually costing £41.4 million. The Welsh Assembly Government explains this increase as being the result of inflation and land costs, saying
3355-414: The west of Ffynnon Wood, the road would then cross back over the original A40 to the east of Henllan Lodge in a way to maintain the tree lined avenue to Henllan, then run parallel to the A40 on the north side of the existing A40 to a new roundabout at Penblewin and the junction with the A478 . This was originally known as the Blue and Purple routes during the Consultation in 2006 for which 75% preferred

The road travels through Cheltenham town centre along at least two parallel routes (neither is part of a one-way system: Sandford Road and Montpellier Terrace make up one part, Thirlestaine Road and Suffolk Road the other). Becoming a dual carriageway, it passes GCHQ in Cheltenham and the three-level stacked roundabout junction with
3477-415: Was created in 1922, under which important routes connecting large population centres, or for through traffic, were designated as Class I, and roads of lesser importance were designated as Class II. The definitive list of those roads was published on 1 April 1923, following consultations with local authorities . Government funding towards the repairs of these roads were set at 60% for the former and 50% for
3538-422: Was decided to reserve the numbers 7, 8 & 9 for Scotland. In Scotland, where roads were the responsibility of the Scottish Office (Scottish Government after 1999), the decision was taken to adopt a scheme whereby motorways took the numbers of the all-purpose routes they replaced. As a result, there is no M7 (as no motorway follows the A7 ), and when the A90 was re-routed to replace the A85 south of Perth ,
3599-436: Was no consistent approach to the renumbering – some A roads retained their existing number as non-primary roads (e.g. the A40 running alongside the M40 ), others were given "less significant" numbers (e.g. the A34 in Warwickshire became the A3400 after the M40 was built), and the remainder were downgraded to B or unclassified roads (e.g. the A38 , which was replaced by the M5 between Tiverton and Exeter ). Occasionally,

The old route (via Acton, Ealing, Southall, Hayes, Hillingdon and Uxbridge) was renumbered the A4020. Initially, the A40 went through the centre of Oxford, via Headington , Magdalen Bridge , the High Street , Carfax and Botley , and over the Swinford Toll Bridge to Eynsham . It
3721-417: Was rerouted in the 1930s to follow the first section of the Oxford Ring Road to the north of the city, and then followed a direct line to bypass Eynsham. The old route became part of the A420 to Botley, and the section between Botley and Eynsham was renumbered the A4141, renumbered again in the 1960s to the B4044. In central London it is High Holborn and then Oxford Street . At Marble Arch it joins
