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 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

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

It is responsible for the English transport network and a limited number of transport matters in Scotland, Wales, and Northern Ireland that have not been devolved . The department is run by the Secretary of State for Transport , currently (since 5 July 2024) Louise Haigh . The expenditure, administration, and policy of
190-551: 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 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,
228-550: 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
266-811: 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 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
304-699: 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, 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
342-684: The A423 . It is now part of the A4130 and the A4074. In the 1980s, when the Dorchester Bypass was opened, the start of the A415 was switched to the western end of the bypass, at Berinsfield.

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.

#1732776223188456-540: 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 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
494-565: The River Thames twice, at Abingdon Bridge and Newbridge . When UK roads were first classified in 1922, the A415 started at a junction with the A4 just west of Maidenhead in Berkshire . It ran through Henley-on-Thames and Benson to Shillingford where it joined the then A42 . It left the A42 a mile west at Dorchester . In the 1930s the section from Maidenhead to Shillingford became part of
532-664: 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 , the short M85 became part of the M90 . In England and Wales, the six single-digit numbers reflect
570-547: 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 was decided to reserve the numbers 7, 8 & 9 for Scotland. In Scotland, where roads were the responsibility of
608-400: 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
646-531: The Department of Transport are scrutinised by the Transport Committee . The Department for Transport has six strategic objectives: The department "creates the strategic framework" for transport services, which are delivered through a wide range of public and private sector bodies including its own executive agencies. The DfT sponsors the following public bodies: DfT publications include

Northern Ireland Reserved matters: The department's devolved counterparts in Northern Ireland are: Northern Ireland's comparability factor (the proportion of spending in this area devolved to the Northern Ireland Executive) was 95.4% for 2021/22. Wales Reserved matters: The department's devolved counterpart in Wales is the Minister for Climate Change. Wales' comparability factor (the proportion of spending in this area devolved to
722-699: The Welsh Government) was 36.6% for 2021/22. This represents a significant reduction (e.g. it was 80.9% in 2015) due to the controversial classification of HS2 as an 'England and Wales' project. The Ministry of Transport was established by the Ministry of Transport Act 1919 ( 9 & 10 Geo. 5 . c. 50) which provided for the transfer to the new ministry of powers and duties of any government department in respect of railways , light railways , tramways , canals and inland waterways , roads , bridges and ferries , and vehicles and traffic thereon, harbours , docks and piers . In September 1919, all
760-540: 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 the M1 the zones were defined for Zones 1 to 4 based on the proposed M2 , M3 and M4 motorways . The M5 and M6 numbers were reserved for
798-834: 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 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
SECTION 20
#1732776223188836-659: The department was reorganised into three major sections: Secretarial, Finance and Roads. The ministry's functions were exercised initially throughout the United Kingdom. An Irish Branch was established in 1920, but then was taken over by the government of the Irish Free State on the transfer of functions in 1922. The department took over transport functions of Scottish departments in the same year, though certain functions relating to local government, loan sanction, byelaws and housing were excepted. In May 1937, power to make provisional orders for harbour, pier and ferry works
874-477: 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 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
912-462: The government committed to implementing in 2017, with 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
950-517: 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 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
988-556: 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 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.
1026-420: The other two planned long distance motorways. 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 the UK was the M1 motorway . Shorter motorways typically take their numbers from a parent motorway in contravention of the zone system, explaining
1064-472: The powers of the Road Board, the Ministry of Health, and the Board of Trade in respect of transport, were transferred to the new ministry. Initially, the department was organised to carry out supervisory, development and executive functions, but the end of railway and canal control by 1921, and the settlement of financial agreements relating to the wartime operations of the railways reduced its role. In 1923,
1102-640: The radials. Lower numbers originate closer to London than higher numbered ones. As roads have been improved since 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
1140-469: The responsibility of: The name "Ministry of Transport" lives on in the annual MOT test , a test of vehicle safety , roadworthiness , and exhaust emissions , which most vehicles used on public roads in the UK are required to pass annually once they reach three years old (four years for vehicles in Northern Ireland ). Following a series of strikes, poor performance, concerns over access for
1178-474: 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 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

1216-757: 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 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
1254-548: 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
1292-405: 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
1330-507: 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 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
1368-405: 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 the original zone boundaries. A few roads are anomalously numbered . Motorways first came to Britain over three decades after
1406-440: 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 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
1444-490: Was transferred to the Secretary of State for Scotland. The growth of road transport increased the responsibilities of the ministry, and in the 1930s, and especially with defence preparations preceding the outbreak of war, government responsibilities for all means of transport increased significantly. Government control of transport and diverse associated matters has been reorganised a number of times in modern history, being
