42-937: List of A roads in zone 9 in Great Britain starting north of the A8 , east of the A9 (roads beginning with 9). An older routing went from the A80 in Pirnhall to the A9 in Bannockburn. Renumbered to a portion of the A91 in the late 1980s. Later allocated to a road from Dufftown to Keith; this became the B9014 when the current A920 replaced the old B9014 from Dufftown to Huntly and other roads. Later allocated between 1947 and 1955 (based on maps) to
84-524: A " T ". Connecting roads were classified as 'link roads", and had route numbers prefixed by an " L ". Many of these roads had their origins in historic routes , including turnpike roads . Although a number of old road signs using these route designations may still be encountered, Ireland has adopted a newer classification scheme of national primary and national secondary routes ("N" roads), regional roads , and local roads . "N" roads remain equivalent to trunk roads in that they are planned and managed at
126-517: A full network map of trunk roads and motorways in England. Most interurban trunk roads are primary routes , the category of roads recommended for long distance and freight transport. Not all primary routes are trunk roads, the difference being that maintenance of trunk roads is paid for by national government bodies rather than the local councils in whose area they lie. Primary routes are identified by their direction signs, which feature white text on
168-630: A green background with route numbers in yellow. Trunk roads, like other "A" roads, can be either single- or dual-carriageway. Historically, trunk roads were listed on maps with a "T" in brackets after their number, to distinguish them from non-trunk parts of the same road, however this suffix is no longer included on current Ordnance Survey maps, which simply distinguish between primary and non-primary "A" roads. A trunk road which has been upgraded to motorway standards may retain its original "A" number, but with an "M" in brackets to denote that motorway regulations apply on it. Long distance examples of this are
210-597: A plan of the route being detrunked. The routes to be detrunked (as set out in detrunking orders) are not always linear sections, but can be split into multiple sections, and span multiple counties. In England, the government has de-trunked much of the trunk road network since the late 1990s, transferring responsibility to local councils to allow National Highways to concentrate on a selection of core trunk routes, mostly dual carriageways and motorways. The most important roads in Sweden are labelled "national trunk road". In 1982,
252-709: A road from Upper Largo to north of Crail as a replacement of the A917 and B942. The A917 and B942 got their sections back while the remainder was downgraded to the B9171. Next used from A9 (now B9152) south of Aviemore to Coylumbridge , formerly a spur of the B970. Returned to the B970 around 1980 after the A9 Aviemore bypass opened. A roads in Great Britain In Great Britain , there
294-591: 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
336-602: A special, slightly larger budget. However, they are not signed in any special way. Therefore, there is no difference in signage, numbering, road standard or map marking from other national roads. Some national roads are only considered trunk for part of their length. National Roads 73 and 75 are both built to motorway standard and have high traffic, but are not considered trunk. European routes are always trunk in Sweden, and are more visible with special numbering. In Ireland, major roads were previously classified under an old system as "trunk roads", and had route numbers prefixed by
378-574: 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
420-463: Is a numbering scheme used to classify and identify all roads. Each road 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
462-463: Is a major highway with a specific legal classification in some jurisdictions, notably the United Kingdom , Sweden and formerly Ireland . Trunk roads are planned and managed at the national-level, distinguishing them from non-trunk roads which are managed by local authorities. Trunk roads are important routes usually connecting two or more cities, ports, airports and other places, which is

#1732788045919504-551: 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,
546-495: 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
588-678: The A1(M) in England, and the A74(M) in Scotland. It is possible for roads to be "de-trunked" – for example, when superseded by a motorway following a similar route – in which case they normally become ordinary "A" roads . When a road is de-trunked, signposts are often replaced, and sometimes route numbers are changed, making the original route of the road harder to follow. Roads are formally and legally detrunked by statutory instruments named 'Detrunking (or sometimes De-Trunking ) Orders' which include
630-761: 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
672-699: 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
714-664: 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. Trunk Roads Act 1936 A trunk road
756-514: The Minister of Transport took direct control of them and the bridges across them. The Trunk Roads Act came into force in England and Wales on 1 April 1937, and in Scotland on 16 May 1937. This development did not extend to Northern Ireland , which has always had a separate system of highway and road traffic law. At that time, 4,500 miles (7,200 km) of British roads were classified as trunk roads. Additional roads have been "trunked", notably in
798-540: 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
840-664: 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
882-990: The Trunk Roads Act 1946 ( 9 & 10 Geo. 6 . c. 30). Others, like virtually all British motorways, have entered the system as a result of new construction. As of 2004, Great Britain had 7,845 mi (12,625 km) of trunk roads, of which 2,161 mi (3,478 km) were motorways. Since 1994, trunk roads in England have been managed by National Highways (formerly Highways England, and before that, Highways Agency), while Scotland has had responsibility for its own trunk roads since 1998 ; these are currently managed by Transport Scotland , created in 2006. The Welsh Government has had responsibility for trunk roads in Wales since its establishment in 1998 . England has 4,300 miles (6,900 km), Scotland has 1,982 miles (3,190 km) and Wales has 1,048 miles (1,687 km) of trunk roads, inclusive of motorways. National Highways publishes

#1732788045919924-547: 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
966-544: 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 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 ;
1008-639: The national roads network in Poland are similar models of nationally planned and managed major highways. In the United States, the U.S. Highway and Interstate Highway systems fulfil a similar role to trunk roads. However, individual states are responsible for actual highway construction and maintenance, even though the federal government helps fund these activities. The states of Michigan, Minnesota, and Wisconsin designate their highways as "state trunklines" or "(state) trunk highways". In India they are
1050-400: 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
1092-540: 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
1134-834: 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
1176-477: 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
1218-462: 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
1260-517: 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
1302-556: 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.

1344-570: The national level by the National Roads Authority . Some former trunk roads, or sections of former trunk roads, became non-trunk regional roads under the new road numbering system introduced in the 1970s and 1980s. More recently, sections of former national primary routes which have been bypassed by motorways or other road improvement schemes have been downgraded to regional road status. The route nationale system in France and
1386-468: 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
1428-493: The parliament decided upon which roads were to become national trunk roads. They are considered recommended main roads for long-distance traffic. They were also supposed to be used for movement and transport of heavy military vehicles, ordnance and logistics and during wartime were to be guarded and defended at all odds. National trunk roads are planned and managed by the national Swedish Transport Administration , as opposed to other roads, which are planned locally. They also have
1470-640: 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
1512-473: The recommended route for long-distance and freight traffic . Many trunk roads have segregated lanes in a dual carriageway , or are of motorway standard. The term trunk road, or trunk highway , is sometimes used more generically to refer to other categories of major highway. In the United Kingdom, trunk roads were first defined for Great Britain in the Trunk Roads Act 1936 ( 1 Edw. 8. & 1 Geo. 6 . c. 5). Thirty major roads were classed as trunk roads, and
1554-474: 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
1596-548: 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
1638-405: 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
1680-507: 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
1722-405: 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

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
