The '''A30''' is a major road in [[England]], running {{convert|284|miles|km|0}} [[boxing the compass|WSW]] from London to [[Land's End]].

The road has been a principal axis in Britain from the 17th century to early 19th century, as a major [[coach (carriage)|coaching]] route and [[post road]].<ref>{{Cite web |title=Bodmin Turnpike Roads |url=http://www.turnpikes.org.uk/Cornwall%20-%20Bodmin%20Roads.htm |website=Turnpike Roads in England and Wales}}</ref><ref>{{Cite web |title=Transport in Cornwall |url=https://www.cornwallheritagetrust.org/timeline/transport-in-cornwall/ |website=Cornwall Heritage Trust}}</ref> It used to provide the fastest route from London to the [[South West England|South West]] by land until a century before roads were numbered; nowadays much of this function is performed by the [[M3 motorway (Great Britain)|M3 (including A316)]] and [[A303 road]]s. The road has kept its principal status in the west from [[Honiton]], [[Devon]] to Land's End where it is mainly [[dual carriageway]] and retains [[trunk road]] status.

==Route==
===London to Honiton===
The A30 begins at Henlys Roundabout, where the route stems from the [[A4 road (England)|A4]] near [[Hounslow]]. It crosses the [[A312 road|A312]] before running south of the Southern Perimeter Road, [[Heathrow Airport]] and north of [[Ashford, Surrey|Ashford]] and [[Staines-upon-Thames]], before reaching the [[M25 motorway]] orbital motorway. This first section is entirely dual carriageway. Taken with the A4, its natural continuation which nearby becomes non-dualled towards the M25, the section constitutes one of five routes into the southern half of London which reach Inner London with at least a dual-carriageway, the others being the [[A3 road|A3]], the [[M3 motorway (Great Britain)|M3]], the [[M20 motorway|M20]] and [[A2 road (Great Britain)|A2]], however approximately one mile before reaching [[Hammersmith and Fulham|Inner London]] it is combined with the London variants of the M3 and M4 approaches.

After running astride the M25 to cross the [[River Thames|Thames]] on a bridge designed by [[Edwin Lutyens|Lutyens]], the [[Runnymede Bridge]], the A30 runs parallel to but distant from the M3 until southwest of [[Basingstoke]], bypassing [[Egham]] and passing through heathland and [[Sunningdale]], [[Bagshot|Bagshot bypass]], and [[Camberley]] where the route almost mirrors the [[Devil's Highway (Roman Britain)|Devil's Highway]], a stone (''stane'') street to [[Calleva Atrebatum]] (Silchester Roman town), believed to be older still, then passes close to [[Hook, Hart|Hook]] town centre and in the surrounding country the soil is arable.

After the 1930s Basingstoke bypass, the M3 changes direction (between [[North Waltham, Hampshire|North Waltham]] and [[Popham, Hampshire|Popham]], at the Popham Interchange) the A303 takes over for {{convert|2|mi}} the A30 losing continuity.{{efn|From [[North Waltham, Hampshire]] to nearby Micheldever Station, the A30 is subsumed into the A303 and one version remains so until [[Sutton Scotney]]/Bullington, the intersection with the Oxford (etc)&mdash;Southampton road, the A34, from where the A30 revives running south along Bullington Lane almost alongside the A34 before resuming a direct west south-westerly route to Salisbury and beyond; however along this combined A303-A30 section at Coxford Hill above [[Micheldever railway station]] an original version branches off linking more directly Sutton Scotney village from that point and enabling a cycle route to avoid Popham and the dual carriageway, taking a detour through North Waltham village.}} From Sutton Scotney village the A30 runs parallel to the latter road [[geodesic datum|as-the-crow-flies]] {{convert|85|mi}} to north-east of Honiton, Devon passing through towns [[Stockbridge, Hampshire|Stockbridge]] (where it meets its first substantive river since the Thames, the [[River Test|Test]]) and its trout fishing centres, [[Shaftesbury]], [[Sherborne]], [[Yeovil]], [[Crewkerne]] and [[Chard, Somerset|Chard]]. Between Stockbridge and Shaftesbury it enters the cathedral city of [[Salisbury]].

Between the M25 and Honiton, the A30 is mostly single carriageway, carrying local traffic with short stretches of dual carriageway from Camberley to Basingstoke, which has a dualled inner ring road, two between Stockbridge and Salisbury (an alike ring road shared with the A36), and between Sherborne and Yeovil.

===Exeter to Penzance===
[[File:ChivertonCrossRoundaboutA30Cornwall.jpg|thumb|left|Approaching the now demolished Chiverton Cross from the east]]
This section is a [[trunk road]] as far as [[Penzance]].<ref>{{cite web|url=http://www.highways.gov.uk/aboutus/18780.aspx |title=Area 1 (map) |publisher=Highways Agency |access-date=22 December 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110921000339/http://www.highways.gov.uk/aboutus/18780.aspx |archive-date=21 September 2011 }}</ref> The route is dual carriageway from Exeter to Camborne in West Cornwall. West of Camborne is mainly single carriageway.

To pass [[Exeter]], through traffic can join the [[M5 motorway]] for {{Convert | 3 | mi | 0 | spell = in}}. West of Exeter, the A30 is dual carriageway through [[Devon]] and into [[Cornwall]], bypassing [[Whiddon Down]], [[Okehampton]] and [[Launceston, Cornwall|Launceston]].

At [[Whiddon Down]] the road previously had a [[roundabout]], known as the Merrymeet junction,<ref>{{Cite news |date=9 March 2005 |title=A30 junction scheme unveiled |url=https://www.tavistock-today.co.uk/news/a30-junction-scheme-unveiled-361967 |work=Tavistock Times Gazette}}</ref> but was replaced in December 2006 by a split-level junction allowing the A30 dual carriageway to run unimpeded by traffic from the A382, in what had been a major cause of traffic.<ref>{{Cite news |date=25 June 2003 |title=Minister unveils Merrymeet layout |url=https://www.tavistock-today.co.uk/news/minister-unveils-merrymeet-layout-355093 |work=Tavistock Times Gazette}}</ref><ref>{{Cite news |date=21 December 2006 |title=Road opens with months to spare |url=http://news.bbc.co.uk/1/hi/england/devon/6201997.stm |work=BBC News}}</ref>

The dual carriageway continues through Cornwall. A Preferred Route Announcement to dual the section from [[Carland Cross]] to [[Chiverton Cross]] was made in July 2017, a Development Consent Order was made in February 2020 by [[Secretary of State for Transport]], and construction started in March 2020. The new section opened in 2024.

From Chiverton Cross, the dual carriageway bypasses [[Redruth]] and [[Camborne]]. The A30 returns to single carriageway west of Camborne, and a mid-1980s bypass takes the road around [[Hayle]]. Between Hayle and Penzance, the A30 returns to the original route and it passes through several villages. Approaching Penzance, the A30 briefly becomes a dual carriageway once again. Once west of Penzance, the A30 becomes a more rural road running through or past several villages, before terminating at Land's End.

==History==
===Post road===
A customary route was long established, even prior to the appointment of [[Brian Tuke]] as [[Postmaster General|Master of the King's Posts]] in 1512, and in [[William Harrison (priest)|William Harrison's]] ''Description of England'' in ''[[Holinshed's Chronicles]]'' in 1577 this is described as a route from London, through [[Chard, Somerset|Chard]], [[Honiton]], [[Exeter]], [[Crockernwell]], [[Okehampton]], [[Launceston, Cornwall|Launceston]], [[Bodmin]], and on through [[Truro]].<ref name=brayshay>{{Cite journal |last=Brayshay |first=Mark |date=December 1991 |title=Royal Post-Horse Routes in South West England in the Reigns of Elizabeth I and James I |url=https://devonassoc.org.uk/wp-content/uploads/2023/07/Brayshay-Royal-post-horse-routes-TDA-1991.pdf |journal=Reports of Transactions of the Devon Association for the Advancement of Science |volume=123 |pages=79–103}}</ref>

In 1574, [[Elizabeth I]]'s Master of Posts [[Thomas Randolph (ambassador)|Thomas Randolph]] was given an [[Order of Council]] to establish permanent posts on the route between the [[royal court]] and Exeter "for the speedy conveyance of all such packets as shall be sent from the Earl of Bedford out of the West Country", with then Earl of Bedford being [[Francis Russell, 2nd Earl of Bedford|Francis Russell]], later [[Lord Lieutenant of Devon]], based at [[Tavistock]]. Whilst court postmaster Robert Gascoigne was tasked the following week, the permanent posts were not in operation until 28 July 1579, when twelve Royal postmasters were in place, at the rate of 20 [[Penny (British pre-decimal coin)|pence]] per day, formalising the route as a Royal [[post road]].<ref name=brayshay/>

This route followed:<ref name=brayshay/>
* the [[City of London]] post room
* [[Hartfordbridge]]
* [[Basingstoke]]
* [[Andover, Hampshire|Andover]]
* [[Salisbury]]
* [[Shaftesbury]]
* [[Sherborne]]
* [[Crewkerne]]
* [[Honiton]]
* [[Exeter]]
* [[Crediton]]

All of these intermediate towns from the 1579 [[post road]] are on (or bypassed by) the modern A30, with the exception of Andover, which the modern road passes to the South of through [[Stockbridge, Hampshire|Stockbridge]], [[Sutton Scotney]], and [[North Waltham]].

There may have been a period of abeyance for some of these posts, but by the late 1580s, the threat of Spanish Invasion reinforced the need for effective communication along the line to [[Plymouth]], for which the post road was the natural route. By 1595, the route was fully re-established to Exeter (and thence on a branch to Plymouth) and the royal route continued to [[Launceston, Cornwall|Launceston]].<ref name=brayshay/> The route into Cornwall was used for passing of messages in relation to the [[Nine Years' War (Ireland)|Nine Years' War]] in Southern Ireland.<ref name=brayshay/>

===17th–18th centuries===
[[File:Ogilby - The Road From LONDON to the LANDS END (1675).jpg|thumb|left|''The Road from LONDON to the LANDS END'' (1675), [[John Ogilby]]]]
The road appeared on [[John Ogilby]]'s 1675 [[Ogilby's "Britannia"|map of Britain]],<ref>{{cite book |chapter=Roads |title=A History of the County of Wiltshire |volume=4 |editor-first=Elizabeth |editor-last=Crittall |publisher= Victoria County History |location=London |year=1959 |pages=254–271 |url=https://www.british-history.ac.uk/vch/wilts/vol4/pp254-271 |access-date=11 August 2016}}</ref> as "The Road from London to The Land's End in Cornwall", where which he described that "The Post-Office making this one of their Principal Roads", and opined that the section through Surrey and Hampshire was "in general a very good Road with suitable Entertainment".<ref>{{cite web|url=http://www.geog.port.ac.uk/webmap/hantsmap/hantsmap/roads/r3notes.htm|title=Old Hampshire Mapped : Ogilby Routes|publisher=Geography Department, Portsmouth University|year=2003|access-date=11 August 2016}}</ref>

The route described by Ogilby started at [[Hyde Park Corner]], and closely mirrored the modern route as far as [[Exeter]], except for three sections from [[Knightsbridge]] to [[Bedfont]], [[Basingstoke]] to [[Salisbury]] via [[Andover, Hampshire|Andover]] and [[Exeter]] to [[Penzance]] via [[Ashburton, Devon|Ashburton]], [[Plymouth]], and following the Cornish south coast via [[St Austell]].<ref>{{cite book|title=The Traveller's Guide: Or, A Most Exact Description of the Roads of England |first=John|last=Ogilby|year=1699|url=https://books.google.com/books?id=twFQAQAAIAAJ&pg=PA205|pages=202–203}}</ref>

The road was known to attract significant postal and coach traffic along its length by 1686.<ref>{{cite report|url=https://www.campop.geog.cam.ac.uk/research/projects/transport/trunkroadspaper.pdf|page=6|title=Identifying the Trunk Roads of Early Modern England and Wales|publisher=The Cambridge Group for the History of Population and Social Structure|date=May 2017|access-date=28 March 2020}}</ref>

The route is described as the "Great Road to Land's End" in the ''[[Magna Britannia]]'', published in the early 19th century.<ref>{{cite book|first1=Daniel |last1=Lysons |first2= Samuel |last2= Lysons|chapter=Geography and geology|series=Magna Britannia|volume=3 |title= Cornwall|location=London|year=1814|pages=clxxxi–cxciii|url=http://www.british-history.ac.uk/magna-britannia/vol3/clxxxi-cxciii|access-date=11 August 2016}}</ref> As the coaching road to Land's End was a major route, it was a popular place for [[highwayman|highwaymen]]. William Davies, also known as the Golden Farmer, robbed several coaches travelling across [[Bagshot Heath]]. He was hanged in 1689 at a gallows at the local gibbet hill between [[Bagshot]] and [[Camberley]]. The [[Jolly Farmer]] pub was built near the site of the gallows (gibbet), a junction.<ref>{{cite book|url=https://books.google.com/books?id=ot6AzT3fO6AC&pg=PA114|title=Green Men & White Swans: The Folklore of British Pub Names|first=Jacqueline|last=Simpson|publisher=Random House|year=2011|isbn=978-0-099-52017-7}}</ref>

===19th century===
[[File:Bridge across the River Yarty, on the A30 - geograph.org.uk - 1567834.jpg|thumb|250px|The A30 crossing the [[River Yarty]]. The road was built by the Chard Turnpike Trust in the mid 19th century to compete with the New Direct Road, later the [[A303 road|A303]].]]
At the turn of the 19th century, William Hanning created the "New Direct Road", a fast coaching route between London and Exeter. The road deviated from Ogilby's route running via [[Amesbury]] and [[Ilminster]], rejoining the older road at Honiton. It became popular with postal services such as ''The Subscription''. In 1831, a race was held between London and Exeter via the New Direct Road, which resulted in a dead heat. {{convert|170|miles}} were covered in 13 hours, compared to a typical early 18th century time of four days.<ref>{{cite book|title=The A303: Highway to the Sun|first=Tom|last=Fort|publisher=Simon and Schuster|year=2012|isbn=978-0-857-20327-4|pages=259, 262–263}}</ref> In response to the competition of routes, a new turnpike road was built west of Chard, avoiding the historic route to Honiton via [[Stockland, Devon|Stockland]], with several steep hills.

====Redruth to Penzance====
In 1825 an [[Act of Parliament]] established the ''Hayle Bridge Causeway and Turnpike Trust'' which was required to construct a bridge, causeway and [[turnpike trust|turnpike]] over the [[River Hayle|Hayle River]] from Griggs Quay ({{gbmapping|SW545363}}) in the west to [[Phillack]] in the east. The turnpike was needed to ease the transport of [[copper ore]] to the port at [[Hayle]] for export. A second Act was passed in 1837 to establish the ''Griggs Quay to Penzance Turnpike'' and in 1839 an Act formed a third trust, the ''Hayle and Redruth Turnpike'' to complete the turnpike to [[Redruth]].{{sfnp|Historic England|1405965|ps=}} The running of the Causeway turnpike was overseen by the winner of a public auction and for the year 1880, the winning bid was £591&nbsp;10s.<ref>{{cite news|last1=Cornish|first1=Thomas|title=Hayle Bridge Causeway and Turnpike Road|work=The Cornishman|issue=115|date=23 September 1880|page=1}}</ref> In 1885 the management of the causeway by the turnpike came to an end, and the White house ([[tollhouse]]) on the eastern end of the Hayle causeway, along with the garden and three granite posts was put up for auction on 30 October 1885.

[[File:China Southern Airlines Airbus A380 arriving at Heathrow over Myrtle Avenue, 8 July 2020.jpg|thumb|right|The Great South West Road section of the A30 borders [[Heathrow Airport]].]]
The A30 was one of the first roads to be classified by the [[Ministry of Transport (United Kingdom)|Ministry of Transport]] for funding in 1921. It followed Ogilby's route up to Exeter, then the basic route of the modern A30 through Okehampton, Launceston and Bodmin to the Greenmarket in Penzance, where it ended.<ref>{{cite web|url=http://www.sabre-roads.org.uk/maps/index.php?view=50.11852,-5.55112&map=NPEMap&zoom=7&layer=4|title=Half Inch Ministry of Transport Road Map|publisher=Ordnance Survey|access-date=22 December 2011}}</ref> It was extended to Land's End in 1925.<ref>{{cite web|url=http://discovery.nationalarchives.gov.uk/details/r/C3543653|title=CLASSIFICATION: Road numbering|publisher=The National Archives|year=1921–1949|url-access=registration }}</ref>

The Great South West Road section of the A30 around Heathrow had been planned as the western end of the Great West Road project, one of the first bypasses built for motor traffic. Construction began in 1914 but was quickly halted because of [[World War I]]. It resumed construction in 1919.<ref>{{cite news|url=http://find.galegroup.com/ttda/infomark.do?&source=gale&prodId=TTDA&userGroupName=wes_ttda&tabID=T003&docPage=article&searchType=BasicSearchForm&docId=CS120261720&type=multipage&contentSet=LTO&version=1.0|title=The Great West Road|newspaper=The Times|date=24 February 1919|page=7|access-date=16 August 2016|url-access=subscription }}</ref> The full route from [[Chiswick]] to [[Ashford, Surrey|Ashford]] was opened by [[George V|King George V]] on 30 May 1925.<ref>{{cite news|url=http://find.galegroup.com/ttda/infomark.do?&source=gale&prodId=TTDA&userGroupName=wes_ttda&tabID=T003&docPage=article&searchType=BasicSearchForm&docId=CS285677740&type=multipage&contentSet=LTO&version=1.0|title=London to the West|newspaper=The Times|date=12 May 1925|page=17|access-date=16 August 2016|url-access=subscription }}</ref>

Following the construction of a bypass around Basingstoke, the route of the A30 was changed on 1 April 1933 to run by [[Sutton Scotney]] and [[Stockbridge, Hampshire|Stockbridge]], rejoining the original route at Lopcombe Corner east of Salisbury. An alternative route, the [[A303 road|A303]] was created out of existing roads at the same time between [[Micheldever Station]] and the [[Blackdown Hills National Landscape|Blackdown Hills]], that followed the basic course of Hanning's New Direct Road.<ref name=tna/> The A30 remained the principal route between London and Exeter, until the A303 became a [[trunk road]] in 1958, receiving central Government funding and relegating the parallel A30 to a local road.<ref>{{cite web|url=https://api.parliament.uk/historic-hansard/written-answers/1958/nov/05/a30-and-a303|title=A.30 and A.303|work=[[Hansard|Parliamentary Debates (Hansard)]]|date=5 November 1958|access-date=16 August 2016}}</ref>

By the mid-20th century, large sections of the A30 were struggling to cope with the increasing demands of road traffic. In the mid-1960s, numerous councils complained that the [[Secretary of State for Transport]], [[Barbara Castle]], decided that improvements to the [[A38 road|A38]] from Exeter to Plymouth were of higher priority for funding than any work on the A30. Cornwall County Council complained that the A30 through the county was narrow and twisted, and known as the "stage coach trail".<ref>{{cite news|title=Road to the West : Ministry's Choice Dismays Cornwall|work=The Times|date=20 June 1966|access-date=11 August 2016|url=http://find.galegroup.com/ttda/infomark.do?&source=gale&prodId=TTDA&userGroupName=wes_ttda&tabID=T003&docPage=article&searchType=BasicSearchForm&docId=CS169044692&type=multipage&contentSet=LTO&version=1.0|url-access=subscription }}</ref>

Following World War II, the Ministry of Transport planned a large-scale upgrade of the A30 across south-west England, with the eventual intention that most of the route would be at least dual-carriageway.<ref>{{cite web|url=https://api.parliament.uk/historic-hansard/written-answers/1958/nov/12/a30-and-a303#S5CV0595P0_19581112_CWA_7|title=A.30 and A.303|work=[[Hansard|Parliamentary Debates (Hansard)]]|date=12 November 1958|access-date=11 August 2016}}</ref> The [[M3 motorway (Great Britain)|M3 motorway]] was planned as a replacement for the A30 between London and [[Popham, Hampshire|Popham]].

The Okehampton bypass, which opened on 19 July 1988, goes to the south of the town, cutting through the northern edge of [[Dartmoor National Park]] in Devon. In the 1980s, the route of the bypass was the subject of a prolonged campaign from conservationists, including [[Sylvia Sayer]], who preferred a route to the north of the town through agricultural land.<ref>{{cite book

The section between Honiton and Exeter in East Devon was upgraded in 1999 to dual carriageway, giving quicker access to [[Exeter International Airport]].
