Sign at Junction 1 of the A1(M) at South Mimms in Hertfordshire
The 'A1' is the longest numbered road in the UK at 409
miles (658
km) long. It connects
London, the
capital city of the
United Kingdom and of
England, with
Edinburgh, the capital of
Scotland. For much of its path it follows the historic 'Great North Road'. The modern course of the A1 diverges somewhat, particularly where it passed through a town or village that has subsequently been
bypassed, or where new motorway standard road has been constructed on a more direct route. Between its junctions with the
M25 (near London) and
A696 (near
Newcastle upon Tyne) the road forms part of the unsigned
Euroroute E15 which runs from
Inverness to
Algeciras.
Origins and history
:''For the numbering rationale see:
Great Britain road numbering scheme''
:''For details of the route and history of the road within the
M25, see
A1 road (London)''
The original A1 route was designated by the
Ministry of Transport in 1921, mostly following the course of the ancient Great North Road. This ran from
Smithfield in Central London, up
St John Street to the
Angel Islington, where it merges with the present A1, which follows a parallel route from
St Pauls up
Aldersgate Street and
Goswell Road to the Angel, Islington. The route then follows
Upper Street and
Holloway Road through
Barnet,
Hertfordshire,
Bedfordshire, to
Alconbury, where it joined the route of a Roman road,
Ermine Street, as far as
Colsterworth, where it is joined by the
A151. The route was modified in 1927 when bypasses were built around
Barnet and
Hatfield, the latter being rebuilt in a tunnel during the 1980s. In 1960
Stamford was bypassed, as was
Retford in 1961 and
St Neots in 1971.
The Great North Road includes stretches of Roman Road including
Dere Street, and is mentioned in much
English literature, for example ''
Pickwick Papers'' by
Charles Dickens.
The legendary
highwayman Dick Turpin's rapid flight from London to York, in less than 15 hours, on his faithful mare Black Bess, is perhaps the most famous legend of the Great North Road. Various inns that still stand along the A1 claim that Turpin ate his lunch there that night, or stopped off there for a brief respite for his horse.
Harrison Ainsworth, in his famous 1834 romance ''
Rookwood'', immortalised this with a spirited account of this wonderful ride by Dick Turpin on his mare, and it is in this connection that Turpin's name has been generally remembered.
However, historians have frequently argued that Turpin never actually made this speedy journey, and that, as far as Turpin is concerned, the incident is pure fiction. They argue that such a ride was really made by
John Nevison, known as "Swift Nick", born and raised at Wortley village near Sheffield and a well-known highwayman in the time of Charles II some 50 years before Turpin, who to establish an alibi rode from Gad's Hill (near Rochester, Kent) to York (some 190 miles) in about 15 hours.
Route

A single carriageway section of the A1 skirting the Scottish coastline just across the border from Northumbria.

A single carriageway section of the A1 in Scotland
The A1 runs from the heart of the
City of London at
St. Paul's Cathedral to the centre of Scotland's capital, Edinburgh.
The A1 shares its
London terminus with the
A40, in the City area of
Central London. It then runs out of London through
Islington (where
Upper Street forms part of its route), up
Holloway Road, through
Barnet,
Potters Bar,
Hatfield,
Welwyn,
Stevenage,
Baldock,
Biggleswade,
Sandy,
St Neots and
Peterborough. Continuing north, the A1 runs on modern bypasses around
Grantham,
Newark-on-Trent,
Retford,
Bawtry,
Doncaster,
Knottingley,
Garforth,
Wetherby,
Knaresborough,
Boroughbridge,
Scotch Corner,
Darlington,
Newton Aycliffe,
Durham,
Chester-le-Street, past the
Angel of the North sculpture in
Gateshead, around
Newcastle upon Tyne,
Morpeth,
Alnwick,
Berwick-upon-Tweed, into
Scotland, past
Dunbar,
Haddington and
Musselburgh before finally arriving in Edinburgh at the East End of
Princes Street near
Waverley Station at the junction of the
A7,
A8 and
A900 roads.

A1 road (London).
Improvements underway
An upgrade of the
Black Cat Roundabout at the junction with the
A421 (Bedford Road) is now complete with the
Great Barford A421 bypass also finished. 2006.
[1]
Work has started in August 2006 to replace the six roundabouts (
Blyth (A614), Apleyhead (A614/A57), Markham Moor (A57), Gonerby Moor (B1174), Colsterworth (A151) and the junction of A1/B6403, and Carpenters Lodge (
Stamford) (B1081)) on the A1 between
Blyth and the A1(M) section to Alconbury with grade separated junctions. Once complete this will provide a fully grade separated route between the Buckden roundabout (just north of St Neots and approximately 4 miles north of the Black Cat roundabout) and just north of
Morpeth.
[2]
Future improvements
There is a proposal to link with the main section of the A14 at
Brampton Hut roundabout with a planned A14 southerly bypass of Huntingdon.
[3]
Improvements to the road north of Newcastle upon Tyne were planned where the road consists mostly of
single carriageway sections as opposed to a combination of
dual carriageway and motorway to the south. Plans to dual the road between
Morpeth and
Felton and between
Adderstone and
Belford were shelved in 2006 as they were not considered a regional priority
[4] by central government. There are no current plans to dual the whole of the A1 route between Newcastle and Edinburgh, despite fierce campaigns in the past to make this so.
The section north of Morpeth is single carriageway and the combination of heavy tourist traffic to locations like
Alnwick Castle ("Hogwarts") and heavy goods vehicles serving Scotland has made the road a notorious stretch with dangerous overtaking, leading to many speed cameras to discourage the practice.
Expressway
In Scotland a section of the road has been upgraded to
motorway standard and classified as a
Special Road, but is not designated as the A1(M). This runs from the east of Edinburgh to Dunbar.
A1(M)
Some sections of the A1 have been upgraded to
motorway standard. These are known as the 'A1(M)'. These include:
★ A stretch between the
M25 at
South Mimms to the town of
Stotfold;
★ The four lane
Peterborough section from the
Alconbury junction near
Huntingdon to
Orton Southgate near Peterborough; this stretch starts just north of the A14 junction proper and receives traffic from the
A14 eastbound from the
M6 and westbound from the
A14 spur and
M11.
★ The
Doncaster bypass, which intersects the
M18 (this was the first section of motorway on the A1 and one of the earliest sections of motorway built in the
United Kingdom);
★ The new Hook Moor section, and South Leeds Orbital, from Darrington, intersects with the
M62 adjacent to
Ferrybridge power station and is joined by the end of the
M1 at Aberford.
★ A relatively new (1993) section which now runs from Wetherby to Dishforth, past
Harrogate,
Ripon and
Boroughbridge. The southern stretch to the
River Wharfe bridge opened in August 2005. This was separated from the existing Hook Moor section by only around 6.5 miles of dual carriageway. The majority of this was replaced in 2006 by a new section taking the A1(M) east of Wetherby, joining the old dual carriageway section for only a mile at Wetherby racecourse, before it opens out again to the three lanes and on to Darrington.
★ The final stretch of A1(M) from Barton just north of
Scotch Corner in North Yorkshire to
Washington in
Tyne and Wear through
County Durham.

This section opened in sections:
★ Junctions 43 to 44 opened in 1999
:When this section opened it ended at a temporary terminus south of the
M1. There was no exit at the southern end for non-motorway traffic, which left non-permitted traffic no where to go.
★ Junctions 40 to 43 opened in 2005 & 2006
:This is the most recent upgrade of the road, which upgraded the previous two-lane
dual carriageway, much of which was on a substandard alignment to a dual 3-lane
motorway. The northern section of the upgrade, bypassing
Fairburn village opened to traffic in April 2005 with a temporary connection with the existing A1 between Fairburn and
Brotherton. The southern section, with a free-flow interchange with the
M62 motorway opened to traffic on
13 January 2006.

Unfulfilled plans
A proposal to replace the road with a parallel motorway between Baldock and Alconbury thus giving a continuous motorway to Peterborough, was dropped as too expensive, despite the very poor alignment and accident record on this section. The same decision dropped the proposed conversion to motorway north of Peterborough to Grantham.
[5]
Future plans
Further sections of motorway upgrades are planned, which would ultimately create a single motorway running from Doncaster to Gateshead.
The next two sections of motorway likely to be built are from
Bramham cum Oglethorpe (the A1(M)/
A64 junction) to
Wetherby, and from
Dishforth (A1(M)/
A168 to
Barton (end of northernmost section of A1(M)). The Bramham to Wetherby scheme
public inquiry began on
18 October 2006.
[6] Designed by James Poyner, construction of the Dishforth to Barton scheme is scheduled to start in April 2008.
Once these two schemes are complete, which is currently scheduled for 2011, then the
Newcastle upon Tyne area will be connected to the rest of the national motorway network. There will be a short section of normal dual-carriageway remaining on the A1 between
Doncaster and the
M62 motorway.
Popular culture
★ Part of the
J.B. Priestley novel ''
The Good Companions'' features the Great North Road, a representation to the northerner Jess Oakroyd as the gateway to such exotic destinations as
Nottingham.
★ The
Lord Peter Wimsey short story "The Fantastic Horror of the Cat in the Bag" by
Dorothy L. Sayers features a motorcycle chase along the Great North Road.
★ Near the southern end are signs saying "
Hatfield and the North". These signs gave their name to 70s rock band
Hatfield and the North.
★ The A1(M) is mentioned in the song "Gabadon" by
Sheffield band
Haze.
