The numbering zones for A-roads in Great Britain

List of A roads in zone 6 in Great Britain starting east of the A6 and A7 roads, and west of the A1 (road beginning with 6).

Single- and double-digit roads

Road	From	To	Notes
	Luton	Carlisle	Originally London to Carlisle, starting from the A1 at Barnet. The fourth longest numbered route in the UK at 299 miles.
	Loughborough	Doncaster
	Derby	Thirsk	Runs through Leeds as the eastern flank of Leeds Inner Ring Road. Forms the primary route between Leeds and Harrogate but is superseded to the south by the M1 motorway to Wakefield. Originally went on what is now the A6135 north of Sheffield.
	Leeds	Manchester	Former main Trans Pennine route from Lancashire to Yorkshire, most of the traffic now uses the M62 motorway, which follows roughly the same route between Manchester and Leeds, but extends to Hull and Liverpool
	Leeds	Kingston upon Hull
	Leeds	Scarborough	Main road from West Yorkshire to the East Coast. Is briefly A64(M) as part of Leeds Inner Ring Road.
	Leeds	Kendal	Trans Pennine route.
	Grangetown	Workington
	Bowes	Crathorne
	Edinburgh	Darlington
	Denton Burn	Carlisle

Triple-digit roads

Road	From	To	Notes
	Hitchin	Bedford	Runs through Shortstown and Cotton End. Originally started in Welwyn, but the section south of Hitchin is now B656, Codicote Road, High Street, and London Road.
			Derby Inner Ring Road. See also the A601(M) motorway in Lancashire. Previously allocated to a road from Luton to near Babraham. Became a portion of the A505 in 1935 when it was extended north to the A11; the section through Hitchin and Baldock is now the B656.
	Hitchin	Ware
	Bedford	Cambridge	Section from Sandy to New Wimpole (on the A1198) downgraded to B1042.
	Unused		Used to run from Barton Seagrave to Harwich. Downgraded to sections of the A14, A1307, A143, A1017, A1124, A137, B1352, A120 and A136 by 1998. The original route went from the A6 at Barton Seagrave to the A14 at Huntingdon. Historically, the Godmanchester to Colchester section was the original A132, and the Colchester to Harwich section was the original A135.
	A14 J13	Hobbs Lot Bridge, near Guyhirn
	Stamford	West Bridgford
	Leicester	Bracebridge Heath
	Newstead	Derby
	Nottingham	Belper
	Nottingham	Ambergate
	Nottingham	Mansfield
	Nottingham	Newark-on-Trent	Runs via Southwell
	Unused		Originally ran from Nuthall to Alfreton. The extension of the M1 to J28 and the completion of the A615 Alfreton bypass (now the A38) resulted in a faster route between Nottingham and Alfreton, and this was the final nail in the coffin for the A613. It was downgraded to the B600, probably in the late 1960s or early 1970s (does not show on maps after that). Later used for the Gateshead Western Bypass from Birtley to Blaydon. Became part of the A69 early on and then the A1 in the 1990s. Number also appears in the DfT Road lists from around 2002 as "Reserved for use for the Kirkumgate - Disforth proposals". Both place names do not exist with these spellings ("Kirkumgate" is probably an archaic spelling for Kirkhamgate and "Disforth" is a typo). The route is likely a descendant of the Kirkhamgate - Dishforth Motorway, a proposal to extend the M1 north between Leeds and Bradford, which later became the A6183, before being rerouted east of Leeds and becoming the M1 extension north of J43.
	Calverton	Bridlington
	Alfreton	Matlock	Former section between Alfreton and Mansfield now part of A38
	Newark-on-Trent	Huddersfield	Becomes M1 motorway between Junctions 30 & 35A
	Chesterfield	Newark-on-Trent
	Clowne	Rotherham
	Bakewell	Worksop
	Ranby	Beckingham
	Sheffield	Baslow

	Sheffield	M18 Junction 4
	Greenland	Louth
	Matlock	Cuckney	Previously allocated to a road from Rotherham to north of Sheffield; this became part of the rerouted A629 at the same time the current A632 was created. The section between old and current A61 is now the B6546.
	Rotherham	New Lodge
	Maltby	A638 near Retford
	Manchester	Doncaster	Trans Pennine route. The westernmost section in Manchester is part of the unsigned A635(M).
	Denby Dale	Wakefield
	Gawber	Grange Moor
	A1 at Markham Moor	M62 Chain Bar junction	Formerly the A1 but renumbered after the construction of the A1 Retford bypass (Markham Moor to Blyth) and the A1(M) Doncaster bypass (Blyth to Carcroft)

	Unused		Ran from Denholme to Brighouse. Renumbered as an extension of the A644 in 1935. Next used from Kegworth to West Bridgford, linking the M1 at J24 to Nottingham; a portion of the route was formally the B679.

	Penrith	Haydon Bridge
	Ingleton	Cantsfield	Originally allocated between Scotch Corner and Darlington (the A1 was routed from Boroughbridge to Darlington via Thirsk and Northallerton). But as early as February 1922, it was decided that the A1 should run via Scotch Corner, as its route was more important. Eventually the MOT caved in to local authority knowledge, and the A687 was one of the first A roads to be decommissioned, becoming the A1.

	Stapleford	Bulwell	Originally ran from Bedford to the A1 near Chawston. Became an extension of the A428 in 1935; the eastern section is now unclassified due to rerouting of the A421 and the western section is now part of the A4280.
	Barton Seagrave	Oakham	Joins A14 opposite A6
	Loughborough	Loughborough railway station	Loughborough Ring Road

	Chorlton-cum-Hardy	Cheetham	Manchester Intermediate Ring Road Originally ran from Stony Middleton to Grindleford Bridge. Downgraded in the 1960s to a portion of the B6521 (the A622 was downgraded at the same time to the B6001).
	Nottingham (Meadow Lane)	Gamston	Originally ran from Grindleford Bridge to the Fox House Inn. Downgraded in the 1960s to a portion of the B6521 (the A622 was downgraded at the same time to the B6001).

	Kettering bypass	Northampton Road, Kettering	Former portion of the A43 before it was rerouted to bypass Kettering. Duplicate number.
	Corby	Great Oakley	Originally on a route cutting the southeast corner between the A6013 and the A57 east of Ashopton. Became a portion of a rerouted A6013 in 1945 due to completion of the Ladybower Reservoir; the northern end is now gone, submerged beneath the reservoir.

	Ashford-in-the-Water	A619 near Bakewell	Acts as a bypass for Bakewell. Originally ran along Commercial Street in Sheffield, linking the A57 to the A61. Although the road was still classified in the 1990s, it did not have the A6020 number (it was moved to its current route in the 1930s) and had likely become a spur of the A57. Now unclassified.
	South East Rotherham	South West Rotherham	Originally used on a route from the A628 Hemsworth Bypass to the A1/A639 junction at Barnsdale Bar, constructed in 2008-2009.

	A628 at Woodhead	Honley
	Brighouse	A629 near Elland

	Shipley	Bradford

Number possibly used in Mansfield (appears on a DfT map from c. 2002), but no further information is known. Before Mansfield town center was bypassed, a tangle of A roads was shown on OS maps, and one of these probably had the A6039 number.

	Uppermill	Denshaw
	Kearsley	A56 near Bury
	Unused		Ran along Marsden Road in Bolton from the A58 and B6203 to the A673. Became a spur of the A673 as a part of the 1935 renumbering, but a photograph from 1937 shows the road as A6054, so the change must have been after 1935.
	Knaresborough	Barton, North Yorkshire	Originally ran from Knaresborough to Boroughbridge; extended to replace the former A1 between Baldersby Gate and Barton after the A1(M) extension opened. Originally used for the northern end of Derby Street in Bolton, linking the A579 to the A568 (now A676). Route is now gone due to redevelopment.

Later the route was extended to go around Samlesbury Aerodrome. In the 1960s the A59 and A677 were given their routes back, but the A6063 was declassified instead of being given its original route.
	Unused		Ran from Rishton to Harwood Bar. Downgraded to the B6535 in the 1970s.
	Unused		First used along Blackburn Road in Accrington from Abbey Street (then A680) to Broadway (then A679). Declassified to remove traffic from the center of Accrington. Ran as a loop off of the A1 along the former A1 via through Newark-on-Trent Renumbered to the A616, B6325 and B6326 because there was no need for a Class I road through Newark after the bypass opened in 1990.
