The A1 is the latest in a series of routes north from London to York and beyond. It was designated in 1921 by the Ministry of Transport under the Great Britain road numbering scheme.{{cn|date=September 2024}} The earliest documented northern routes are the roads created by the Romans during the period from AD 43 to AD 410, which consisted of several itinera (plural of iter) recorded in the Antonine Itinerary.{{cite book|url=http://www.roman-britain.org/antonine-itinerary.htm |title=Roman Roads in Britain – Antonine Itinerary |publisher=Society for Promoting Christian Knowledge |year=1903 |via=roman-britain.org |first=Thomas |last=Codrington |access-date=23 August 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110703033434/http://roman-britain.org/antonine-itinerary.htm |archive-date=3 July 2011 }} A combination of these were used by the Anglo-Saxons as the route from London to York, and together became known as Ermine Street.{{cite web |url=https://penelope.uchicago.edu/Thayer/E/Gazetteer/Periods/Roman/Topics/Engineering/roads/Britain/_Texts/CODROM/4*.html#1 |title=LacusCurtius • Codrington's Roman Roads in Britain – Chapter 4 |first=Thomas |last=Codrington |work=penelope.uchicago.edu |access-date=23 August 2011}} Ermine Street later became known as the Old North Road.{{cite book |url= https://books.google.com/books?id=Rp66hfjBogcC&pg=PA14|title=Great North Road |first=Frank |last=Goddard|page=14|publisher=Frances Lincoln Ltd|year=2004 |access-date=23 August 2011 |isbn= 978-0-7112-2446-9}} Part of this route in London is followed by the current A10.{{cite book |url= https://books.google.com/books?id=sAA9olZqPSMC&pg=PA343|title=The London Encyclopedia |page=343|first=Christopher |last=Hibbert |first2=Ben |last2=Weinreb|publisher=Pan Macmillan|year= 2009 |access-date=23 August 2011 |isbn= 978-1-4050-4925-2}} By the 12th century, because of flooding and damage by traffic, an alternative route out of London was found through Muswell Hill, and became part of the Great North Road. A turnpike road, New North Road and Canonbury Road (A1200 road), was constructed in 1812 linking the start of the Old North Road around Shoreditch with the Great North Road at Highbury Corner.{{cite book |url= https://books.google.com/books?id=4IJnAAAAMAAJ|title=The London Encyclopedia |page=541|first=Christopher |last=Hibbert |first2=Ben |last2=Weinreb|publisher=Macmillan|year= 1983|access-date=23 August 2011 |isbn= 978-0-333-32556-8}} While the route of the A1 outside London mainly follows the Great North Road route used by mail coaches between London and Edinburgh, within London the coaching route is only followed through Islington.Norman W. Webster (1974) The Great North Road

The Ferryhill Cut was opened in 1923. A number of bypasses were built from 1926 onwards, including around Barnet and Hatfield in 1927, but it was not until {{circa|1954}} that they were renumbered A1. The Chester-le-Street bypass, opened in 1931, was the first bypass to be built as a dual carriageway. In 1960 Stamford, Biggleswade and Doncaster were bypassed, as was Retford in 1961. Baldock, Eaton Socon and Buckden were bypassed in 1967. During the early 1970s plans to widen the A1 along Archway Road in London were abandoned after considerable opposition and four public inquiries during which road protesters disrupted proceedings.{{cite book|url=https://books.google.com/books?id=Hyg-AAAAIAAJ&pg=PA62|title=Transport planning, vision and practice|isbn=978-0-7100-0844-2|last1=Adams|first1=John|year=1981|publisher=Routledge & K.

A proposal to upgrade the whole of the A1 to motorway status was investigated by the government in 1989{{cite web|url=https://api.parliament.uk/historic-hansard/written-answers/1989/jul/14/a1-motorway-status|title=A1 (Motorway Status) |website=Parliamentary Debates (Hansard)|date=14 July 1989|access-date=15 November 2021}} but was dropped in 1995, along with many other schemes, in response to road protests against other road schemes (including the Newbury Bypass and the M3 extension through Twyford Down).{{cite web|url=https://publications.parliament.uk/cgi-bin/newhtml_hl?DB=semukparl&STEMMER=en&WORDS=a1%20baldock&ALL=a120baldock&ANY=&PHRASE=&CATEGORIES=&SIMPLE=&SPEAKER=&COLOUR=red&STYLE=s&ANCHOR=51220w05.html_spnew6&URL=/pa/cm199596/cmhansrd/vo951220/text/51220w05.htm#51220w05.html_spnew6 |publisher=Hansard|date=20 December 1995|title=Column: 1180|access-date=20 January 2008}}

File:The Angel Inn - North Street - geograph.org.uk - 553280.jpg is a coaching inn on the former A1, bypassed since the 1950s.]]

The inns on the road, many of which still survive, were staging posts on the coach routes, providing accommodation, stabling for the horses and replacement mounts. Few of the surviving coaching inns can be seen while driving on the A1, because the modern route now bypasses the towns with the inns.

The A1 runs from New Change{{citation needed|date=September 2022}} in the City of London at St. Paul's Cathedral to the centre of Edinburgh. It shares its London terminus with the A40,{{citation needed|date=September 2022}} in the City area of Central London. It runs out of London via St. Martin's Le Grand and Aldersgate Street, through Islington (where Goswell Road and Upper Street form part of its route), up Holloway Road, through Highgate, and Barnet.

The road enters Hertfordshire just before Potters Bar, near the junction with the M25 at the South Mimms Services. The route here becomes the A1(M) and subsequently passes through Hatfield, Welwyn, Stevenage, Baldock. But it once again becomes a dual carriageway from Baldock Junction 10 through Biggleswade, Sandy, several small villages to Buckden then on to Alconbury Junction 14. Junctions 11, 12 and 13 are still to be planned/built. Several groups along this non motorway stretch are actively campaigning for an upgrade to modern standards.

Continuing north, the A1 runs on modern bypasses around Stamford, Grantham, Newark-on-Trent, Retford, Bawtry, Doncaster, Knottingley, Garforth, Wetherby, Knaresborough, Boroughbridge, Scotch Corner, Darlington, Newton Aycliffe, Durham and Chester-le-Street, past the Angel of the North sculpture and the Metrocentre in Gateshead, through the western suburbs of Newcastle upon Tyne, Morpeth, Alnwick, Berwick-upon-Tweed, into Scotland at Marshall Meadows, past Haddington and Musselburgh before arriving in Edinburgh at the East End of Princes Street near Waverley Station, at the junction of the A7, A8 and A900 roads.

Scotch Corner, in North Yorkshire, marks the point where before the M6 was built, the traffic for Glasgow and the west of Scotland diverged from that for Edinburgh.{{cn|date=November 2024}} As well as a hotel there have been a variety of sites for the transport café, now subsumed as a motorway services.

There are five roundabouts north of the Sterling corner junction: Biggleswade south, Biggleswade north, Sandy A603, Black Cat A428/A4211, lastly Buckden, after which there are no more roundabouts for {{convert|276|mi|km|abbr=on}} until the Berwick A1167. The Black Cat roundabout is due to be removed in 2025.

Plans to dual the single carriageway section of road north of Newcastle upon Tyne were shelved in 2006 as they were not considered a regional priority by central government. The intention was to dual the road between Morpeth and Felton and between Adderstone and Belford.[http://www.northumberlandtoday.co.uk/ViewArticle2.aspx?SectionID=1117&ArticleID=1625204] {{Dead link|date=June 2020|bot=InternetArchiveBot|fix-attempted=yes}}

In 1999 a section of A1(M) between Bramham and Hook Moor opened to traffic along with the extension of the M1 from Leeds.{{cn|date=September 2024}} Under a DBFO contract,{{cite web|url=http://www.highways.gov.uk/roads/projects/5541.aspx|title=Darrington to Dishforth|publisher=Highways Agency|page=1|access-date=20 February 2010|url-status=dead|archive-url=https://web.archive.org/web/20100417222742/http://www.highways.gov.uk/roads/projects/5541.aspx|archive-date=17 April 2010}} sections from Wetherby to Walshford and Darrington to Hook Moor were opened in 2005 and 2006.

Between September 2006 and October 2009 six roundabouts on the A1 and the A1(M) to Alconbury were replaced with grade-separated junctions. These provide a fully grade-separated route between the Buckden roundabout (just north of St Neots and approximately {{convert|8|mi}} north of the Black Cat roundabout) and just north of Morpeth.{{cite web|url=http://www.highways.gov.uk/roads/projects/4455.aspx|title=A1 Peterborough to Blyth Grade Separated Junctions Scheme|publisher=Highways Agency|access-date=20 January 2008|url-status=dead|archive-url=http://webarchive.nationalarchives.gov.uk/20120810124133/http://www.highways.gov.uk/roads/projects/4455.aspx|archive-date=10 August 2012}} This project cost £96 million.{{cite web|url=http://www.bettertransport.org.uk/campaigns/climate_change/roads/pricetag|title=Bigger and bigger pricetag|url-status=dead|archive-url=https://web.archive.org/web/20090925050256/http://www.bettertransport.org.uk/campaigns/climate_change/roads/pricetag|archive-date=25 September 2009}}

Upgrading the {{convert|6.2|mi|km|0}} of road to dual three-lane motorway standard between the Bramham/A64 junction to north of Wetherby to meet the section of motorway at a cost of £70 million began in 2006, including a road alongside for non-motorway traffic. The scheme's public inquiry began on 18 October 2006 and the project was designed by James Poyner. Work began in May 2007, the motorway section opened in July 2009 and remaining work on side roads was still ongoing in late August and was expected to be completed by the end of 2009.{{cite web|url=http://www.highways.gov.uk/roads/projects/5526.aspx |title=A1(M) Bramham to Wetherby Improvement Scheme |publisher=Highways Agency |access-date=20 January 2008 |archive-url=https://web.archive.org/web/20080118200404/http://www.highways.gov.uk/roads/projects/5526.aspx |archive-date=18 January 2008 |url-status=dead }}

Upgrading of the existing dual carriageway to dual three-lane motorway standard, with a local road alongside for non-motorway traffic, between Dishforth (A1(M)/A168 junction) and Leeming Bar, began in March 2009 and opened to traffic on or about the scheduled date of 31 March 2012.{{cite web|url=http://www.highways.gov.uk/news/pressrelease.aspx?pressreleaseid=423810|title=A1(M) upgrade in North Yorkshire nears completion – even more motorway for road users|publisher=Highways Agency|access-date=21 March 2012|archive-url=https://web.archive.org/web/20080209132503/http://www.highways.gov.uk/roads/projects/5187.aspx|archive-date=9 February 2008|url-status=dead}}

It had originally been proposed that the road would be upgraded to motorway from Dishforth to Barton (between Scotch Corner and Darlington), which was the start of current northernmost section of A1(M). In 2010 the section between Leeming and Barton was cancelled as part of government spending cuts{{cite web|url=http://www.constructionenquirer.com/2010/10/21/details-emerge-of-dumped-road-schemes/|title=Details emerge of dumped road schemes|publisher=Construction Enquirer|access-date=6 January 2011}} but it was reinstated in December 2012.{{cite book|url=http://cdn.hm-treasury.gov.uk/autumn_statement_2012_complete.pdf|title=Autumn Statement 2012|date=5 December 2012|publisher=Her Majesty's Stationery Office|isbn=978-0-10-184802-2|access-date=5 December 2012|archive-url=https://web.archive.org/web/20121224001641/http://cdn.hm-treasury.gov.uk/autumn_statement_2012_complete.pdf|archive-date=24 December 2012|url-status=dead}} Work began on 3 April 2014 and was expected to be completed by Spring 2017, but only reached completion in March 2018 due in part to significant Roman-era archaeological finds along the route of the motorway. Completion has provided a continuous motorway-standard road between Darrington (south of M62 junction) and Washington, and given the North East and North Yorkshire full motorway access to London (via the M1 at Darrington and Hook Moor).

Councils in the north east have called for the section from Hook Moor in Yorkshire (where the M1 link road joins the A1(M)) to Washington to be renumbered as the M1. They maintain that this would raise the profile of the north-east and be good for business.{{cite news|url=http://www.thenorthernecho.co.uk/news/transport/14125291.Civil_engineers_back_call_to_rename_A1_M_/|title=Civil engineers back call to rename A1(M)|last=Kearney|first=Tony|date=4 December 2015|work=The Northern Echo|access-date=26 December 2015}}

In his Autumn Statement on 5 December 2012, the Chancellor of the Exchequer announced that the Government would upgrade a section of road from two to three lanes in each direction within the highway boundary at Lobley Hill (between Coal House and the Metro Centre), Gateshead at a cost of £64 million{{cite news|url=https://www.bbc.co.uk/news/uk-england-20609774|title=Autumn Statement: A1 to be upgraded to motorway status|work=BBC News|date=5 December 2012 }} and create parallel link roads between the Lobley Hill and Gateshead Quay junctions. The same Road investment strategy announcement said that the remaining section of road between Birtley and Coal House will also be widened to three lanes each way, alongside the replacement of the Allerdene Bridge. A modified scheme commenced in August 2014 and was open to traffic in June 2016. The road is now three lanes each way with lane 3 narrower than lanes 1 and 2 so that all existing bridges remained as originally built.{{cite web|url=http://www.highways.gov.uk/roads/road-projects/a1-coal-house-to-metro-centre-improvement/|title=A1 Coal House to Metro Centre Improvement|archive-url=http://webarchive.nationalarchives.gov.uk/20160607085337/http://www.highways.gov.uk/roads/road-projects/a1-coal-house-to-metro-centre-improvement/|archive-date=7 June 2016|url-status=dead}}

The A1 around Durham, Gateshead and Newcastle has seen a number of incarnations, following routes through, to the east and to the west of both Gateshead and Newcastle. See A1 (Newcastle upon Tyne) for more information.

{{Main|A14 road (England)}}

The A14 Ellington to Fen Ditton scheme, also known as the Huntingdon Bypass required a redesigned interchange at Brampton. As a result the A1 was widened to a D3 standard from the current end of the A1(M) to the slip roads connecting directly onto the A14. South of the new Interchange the A1 was realigned but kept as a 2 lane dual carriageway. This scheme was meant to result in the A1 becoming the A1(M) along the upgraded sections, however the legal proceedings for this did not take place, and instead features a large amount of restrictions, similar to a motorway. This scheme was opened in December 2019.

The new junction is now complete on the A1 south of Grantham, Highways England constructed 4 new slip roads to connect the A1 Trunk Road to the new Grantham Southern Relief Road (A52) being constructed by Lincolnshire County Council. This will create a southern entry to Grantham and also to the site known as the 'King 31 Development'.{{cite web |title=The A1 Trunk Road (Grantham Southern Growth Corridor) (Slip Roads) Order 2019 |url=https://www.legislation.gov.uk/uksi/2019/570/schedule/made |access-date=15 November 2021 |website=Legislation.gov.uk}} The Grade Separated Junction on the A1 was opened to traffic in December 2022.{{cite web |title=Spittlegate Junction – Roader's Digest: The SABRE Wiki |url=https://www.sabre-roads.org.uk/wiki/index.php?title=Spittlegate_Junction |access-date=10 December 2024 |website=www.sabre-roads.org.uk}} The on-going phase three is the Southern Quadrant Link Road (SQLR), which will complete the relief road and is expected to be completed in 2025.{{cite web |last=Schubert |first=Chris |title=Grantham Southern Relief Road |url=https://www.lincolnshire.gov.uk/major-projects/grantham-southern-relief-road |access-date=26 September 2023 |website=Lincolnshire County Council }}{{cite web |date=16 October 2023 |title=Newark £100m link road completion project under way – Highways News |url=https://highways-news.com/newark-100m-link-road-completion-project-under-way/ |access-date=10 December 2024 }}

A1 Scotswood to North Brunton Upgrade

The A1 road, a key route in Great Britain, has seen several major developments in recent years. Notably, the A1 Scotswood to North Brunton upgrade, completed in November 2022, represents a significant enhancement of the route. This project, valued at approximately £110 million, added an additional lane in each direction between junctions 74 and 79, covering a distance of five miles. It was expected to boost economic activity in the North East by improving access to services, businesses, and housing. The upgrade also had a positive environmental impact, reducing carbon emissions by over 8,000 tonnes, thanks to methods such as reusing materials and employing sustainable drainage systems.{{cite web |title=Highways Magazine – a1 |url=https://www.highwaysmagazine.co.uk/a1 |access-date=10 December 2024 |website=www.highwaysmagazine.co.uk}}

The A1 between Junctions 65 (Birtley) & 67 (Coal House) on the Newcastle Bypass is currently being widened to a D4 cross section from the existing D2 cross section, this includes replacing the existing bridge over the East Coast Main Line.{{cite web |title=A1 Birtley to Coal House Improvement Scheme – Project information |url=https://national-infrastructure-consenting.planninginspectorate.gov.uk/projects/TR010031 |access-date=10 December 2024 |website=national-infrastructure-consenting.planninginspectorate.gov.uk}}{{cite web |last=Highways |first=National |date=15 May 2024 |title=Drivers advised to allow more time to travel as contraflow installed on A1 near Gateshead – National Highways |url=https://nationalhighways.co.uk/article/drivers-advised-to-allow-more-time-to-travel-as-contraflow-installed-on-a1-near-gateshead/ |access-date=10 December 2024 |website=nationalhighways.co.uk }} Works started in December 2021 and are due to be completed in 2025.

In December 2014 a scheme was announced to dual the A428 from the A1/A421 Black Cat roundabout to Cambourne. This would include significant works to the A1/A421 Black Cat roundabout. The existing traffic signal controlled roundabout would be replaced with a grade-separated junction.{{cite web |title=Major roads investment in the east of England |url=https://www.gov.uk/government/news/major-roads-investment-in-the-east-of-england |access-date=15 November 2021 |website=Gov.uk}} The new Grade Separated Junction would allow the A1 and A421 traffic to pass over each other, with a middle level roundabout connecting them together including links to local roads. Many direct accesses on the A1 would be stopped up and diverted onto new local access roads. The scheme started construction in late 2023, the works currently underway along the A1. When completed this will remove one of the last 5 roundabouts on the A1 from Sterling corner to the Berwick bypass.{{cite web|url=https://nationalhighways.co.uk/our-roads/a428-black-cat-to-caxton-gibbet/|title=A428 Black Cat to Caxton Gibbet improvements |publisher=National Highways|date=18 October 2021|website=nationalhighways.co.uk|accessdate=8 July 2024}} The replacement of the Black Cat Roundabout as part of the A428 Black Cat to Caxton Gibbet improvements project is currently ongoing. The £1 billion infrastructure scheme aims to significantly improve traffic flow and connectivity across the region. The project will upgrade the Black Cat roundabout into a modern, free-flowing junction, with work set to continue until 2027. As of 2024, National Highways has made substantial progress, including the installation of key infrastructure such as bridges and slip roads. Recent developments include the completion of major bridge installations, with several closures planned to accommodate large-scale construction activities, such as the installation of steel beams for the Roxton Road bridge.{{cite web |date=14 December 2023 |title=Highways Magazine – Work on £1bn Black Cat scheme finally begins...really, it does |url=https://www.highwaysmagazine.co.uk/Work-on-1bn-Black-Cat-scheme-finally-begins...really-it-does/13653 |access-date=10 December 2024 |website=www.highwaysmagazine.co.uk }}{{cite web |date=25 October 2024 |title=A421 in Bedfordshire to close for two weekends as National Highways lifts bridge beams into place – Highways News |url=https://highways-news.com/a421-in-bedfordshire-to-close-for-two-weekends-as-national-highways-lifts-bridge-beams-into-place/ |access-date=10 December 2024 }}

The A1 continues to undergo significant improvement as part of the broader effort to modernise the UK’s transport infrastructure. National Highways, responsible for overseeing roadworks on motorways and major A roads, has outlined plans for continued investment in the A1 to support both local traffic and freight transport. These upgrades are expected to alleviate congestion, improve safety, and support the economy by enhancing the accessibility of key business and service hubs across the North East.{{cite web |title=Boost to the North East economy as multi-million pound A1 upgrade opens to traffic |url=https://www.costain.com/media/press-releases/2022/boost-to-the-north-east-economy-as-multi-million-pound-a1-upgrade-opens-to-traffic/ |access-date=10 December 2024 |website=www.costain.com }}

These projects are part of an ongoing effort to expand the A1 from its current dual carriageway sections into full motorway status in certain areas, a development that is expected to improve traffic flow and reduce accidents.

In the "Road investment strategy" announced to Parliament by the Department for Transport and Secretary of State for Transport on 1 December 2014, planning will begin to upgrade the road in South Yorkshire to raise the last non-motorway section from Red House to Darrington to motorway standard.{{cite web|url=https://www.gov.uk/government/news/major-roads-investment-in-the-north-east-and-yorkshire|title=Major roads investment in the north east and Yorkshire|website=Gov.uk|access-date=15 November 2021}} Once completed, it will provide a continuous motorway-standard road between Blyth, Nottinghamshire and Washington, Tyne and Wear and will provide the North East and Yorkshire with full motorway access to London via the M1, M62 and M18. It will also improve safety along this route, as well as creating a new corridor to the North East, and reducing congestion on the M1 around Sheffield and Leeds. This is the only missing link of motorway on the strategic M1/M18/A1(M) route London to Washington.

The announcement then said that the road from Morpeth to Ellingham would be upgraded to dual carriageway. The selection of the preferred route was scheduled for the year 2017, with construction due to begin in 2019.{{cite web |url=https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/424467/DSP2036-184_Highways_England_Delivery_Plan_FINAL_low_res_280415.pdf |title=Highways England Delivery Plan 2015–2020 |access-date=5 August 2015}} In response to questions regarding transport in the north, Highways England stated that a new dual carriageway section between Morpeth and Felton and also that of Alnwick to Ellingham would start in 2021 with full opening in 2023.{{cite news |title=Your transport questions answered |url=https://www.bbc.co.uk/news/uk-england-45061611 |access-date=8 August 2018 |work=BBC News |date=3 August 2018}} However in June 2022 UK government minister Grant Shapps delayed a decision about a Development Consent Order signing off on National Highways' plans until December 2022.{{cite news |title=Plea for 'swift' decision on long-awaited A1 dualling in Northumberland after double delay |url=https://www.chroniclelive.co.uk/news/north-east-news/a1-dualling-northumberland-double-delay-24480979 |access-date=29 August 2022 |work=ChronicleLive |date=13 July 2022}}

Measures were also announced to enhance the performance and safety of the A1 north of Ellingham to include three sections of climbing lanes, five junctions with improved right turn refuges, and better crossing facilities for pedestrians and cyclists. Start of construction is scheduled for 2018.

It was then also announced that planning would begin to upgrade the Newark northern bypass to dual carriageway, and the A46 junction with the A1 will be replaced to support nearby housing growth and improve links from the A1 to Newark and Lincoln.{{cite web|url=https://www.gov.uk/government/news/major-roads-investment-in-the-midlands|title=Major roads investment in the Midlands|website=Gov.uk|access-date=15 November 2021}} The DCO is due to be submitted in early 2024, with construction likely to start in 2026 if approved.

It was also announced that the Doncaster By-pass, which is the oldest stretch of two-lane motorway still in service, would be upgraded to dual three lanes. This will relieve local congestion and provide the capacity needed to make the A1 an alternative (and better) strategic route to the north east.

It was also announced in 2014 that new technology would be implemented to bring the road to motorway standards, including detection loops, CCTV cameras and variable message signs to provide better information for drivers and active traffic management across Tyne and Wear, while Junction 6 (Welwyn North) to Junction 8 (Hitchin) would be upgraded to smart motorway, including widening of a two-lane section to dual three lanes and hard shoulder running. This plan to upgrade to smart motorway has now been cancelled.{{cite web |last=Highways |first=National |date=7 May 2020 |title=A1(M) junction 6 to junction 8 smart motorway – National Highways |url=https://nationalhighways.co.uk/our-roads/east/a1-m-junction-6-to-junction-8-smart-motorway/ |access-date=26 September 2023 |website=nationalhighways.co.uk }}

A strategic study will examine how to improve the safety and performance of the A1 between Peterborough and the M25, including whether to upgrade the old dual carriageway section to motorway standard.

Some sections of the A1 have been upgraded to motorway standard. These are known as the A1(M) and include:

The M25 to Stotfold section is {{convert|23|mi|km}}, and was constructed between 1962 and 1986. The main destinations are Hatfield, Welwyn Garden City, Stevenage, and Letchworth. It opened in five stages: junctions 1 to 2 in 1979; 2 to 4 in 1986; 4 to 6 in 1973; 6 to 8 in 1962; and 8 to 10 in 1967.

The Alconbury to Peterborough section is {{convert|14|mi|km}}, and opened in 1998.

The Doncaster By-pass opened in 1961 and is one of the oldest sections of motorway in Britain.{{cite web|url=http://www.ciht.org.uk/motorway/stats.htm |title=The Motorway Archive. Oldest, widest, longest, highest. |work=ciht.org.uk |year=2008 |access-date=28 July 2011 |url-status=dead |archive-url=https://web.archive.org/web/20100122131318/http://www.ciht.org.uk/motorway/stats.htm |archive-date=22 January 2010 }} It is {{convert|15|mi}} long, and runs from Blyth to Carcroft.

The Darrington to Gateshead section was constructed between 1965 and 2018. It is {{convert|93|mi|km}}, and opened in sections:

• Junctions 56 to 59 in 1965
• Junctions 59 to 63 in 1969
• Junctions 63 to 65 in 1970
• Walshford to 49 in 1995
• Junctions 43 to 44 in 1999

:When this section opened it ended at a temporary terminus south of the M1. There was a final exit into Micklefield Village for non-motorway traffic onto what is now the access road. During the first week of June 2009, Junctions 44 and 45 were renumbered 43 and 44. At the same time the A1/A659 Grange Moor junction became A1(M) Junction 45.{{cite web

• Junction 46 to temporary junction at Walshford opened in 2005{{cite web|url=http://www.highways.gov.uk/roads/projects/5523.aspx|title=A1(M) Wetherby to Walshford|publisher=Highways Agency|access-date=6 August 2008|archive-url=https://web.archive.org/web/20080830002409/http://www.highways.gov.uk/roads/projects/5523.aspx|archive-date=30 August 2008|url-status=dead}}
• Junction 40 to south of 43 opened in 2005 & 2006

:The northern section of the upgrade, bypassing Fairburn village opened in April 2005 with a temporary connection with the A1 between Fairburn and Brotherton. The southern section, with a free-flow interchange with the M62 motorway opened on 13 January 2006.
