The numbering zones for A-roads in Great Britain

Single- and double-digit roads

Road	From	To	Notes
A5	Central London (Marble Arch)	Holyhead	Forms parts of the historical route of Watling Street. The section from M1 J4 north of Edgware to N. of Dunstable is now numbered A5183. The A5 now starts at M1 J11A and runs west to join previous alignment.
A50	Leicester	Warrington	Becomes M1 motorway between junctions 22 and 24A. Used to start at Hockliffe on A5, north of Dunstable. Gradually cut back to Northampton, then Leicester. Before opening of Derby southern bypass in 1997, it followed present A511 between Markfield and Foston.
A51	Chester	Kingsbury	Formerly ending at the A5 in Tamworth, the road to the south was the northern end of the A423. When the latter was downgraded north of Coventry, the A51 was extended to the A47. Subsequently, the A47 too was downgraded (to the B1114) and the A51 was then cut back to its present terminus near Kingsbury.
A52	Newcastle-under-Lyme	Mablethorpe
A53	Buxton	Shrewsbury
A54	Chester	Buxton	The section between Congleton and Buxton is the most dangerous road in Britain.
A55	Holyhead	Chester	Also known as the "North Wales Expressway".
A56	Chester	A59 near Broughton
A57	Liverpool	Lincoln
A58	Prescot	Wetherby	Becomes A58(M) as part of Leeds Inner Ring Road
A59	Liverpool	York

Three-digit roads

Road	From	To	Notes
A500	Clayton	Nantwich	Known locally as the D Road, either because its route resembles the curved part of a letter D (with a section of the M6 forming the upright) or after the Roman numeral 'D' (500). Originally ran from the A5 at Marble Arch to the A1 at Tally Ho Corner in North Finchley. In 1935 it was extended and rerouted over the A5088 Watford Bypass (the original route became the A598). Renumbered to A41 in the 1950s when it was deemed sensible to give the lower numbers of the bypassed routes to new-build bypasses and radials north of London.
A501	Westway (London)	Moorgate	Part of the London Inner Ring Road, comprises Marylebone Road, Euston Road, Pentonville Road and City Road. Terminates at junction with London Wall.
A502	Camden Town	Hendon	Through Hampstead, broadly follows the Edgware branch of the Northern Line for 5 stations.
A503	Camden Town	Woodford	Camden Road and Seven Sisters Road (primary) and Ferry Lane (non-primary), though Holloway and Walthamstow
A504	West Hendon	Tottenham Hale	via Hendon, Finchley, East Finchley, Muswell Hill, Hornsey and West Green. Has recently been extended to include Broad Lane as the A503 is now two-way.
A505	Leighton Buzzard	Great Abington
A506	Walton	Stanley Gate nr. Bickerstaffe	Part of the road has since been reassigned to the M58 Motorway; in the 1970s part of it served the New Town of Skelmersdale Originally ran from the A5 in Hockliffe to the A508 south of Northampton. Became a southern extension of the A50 in 1935 and has since been downgraded (one section is now B526).
A507	Buntingford	M1 junction 13	The northern terminus and the course of the road have recently been changed to bypass Ridgmont.
A508	Old Stratford	Market Harborough
A509	Milton Keynes	Kettering	Forms the H5 Portway in Milton Keynes.
A510	Wellingborough	Cranford St John	Forms part of Wellingborough's outer ring road, passes through Finedon and ends at Junction 11 of the A14 at Cranford St John.
A511	Markfield	Foston, Derbyshire	Historical A50(T). The original route went from Atherstone to Burton upon Trent; the Atherstone-Twycross section became the B4116 and the Twycross-Burton section became a northern extension of the A444 in 1935. The A511 number also appeared in the "Co-driver: The AA Motorists Companion" (1965) on a route linking the M6 to Wigan. Only the first section east of the M6 was built, however, and it is designated as the A5209.
A512	Loughborough	A42 & A511 near Ashby-de-la-Zouch
A513	Tamworth	Stafford	Starts in Stafford, running through the town of Rugeley (although the road here is broken at Armitage Road due to recent road changes including the re-routing of the A51 which is now the Rugeley Eastern By-Pass (which runs south to Tamworth).
A514	Derby	Swadlincote	It is a 15-mile (24 km) stretch of single-carriageway road which crosses the A5111 Derby ring road before a separated grade junction with the dual-carriageway A50 road. A little further south, the A5132 runs off to the west, just before the A514 crosses the River Trent over the narrow and historic Swarkestone Bridge. The next significant junction is with the A511, where it enters a built up area. The road continues through Swadlincote, and terminates at its junction with the A444 road (52.7670°N 1.5924°W / 52.7670; -1.5924 (A514 road (southern end))) just west of the town.
A515	Lichfield	Buxton
A516	Derby	Hilton
A517	Belper	Ashbourne
A518	Uttoxeter	Telford	Between Uttoxeter and Stafford it is a single carriageway, with a staggered junction with the dual carriageway A51. Entering Stafford from the east, it passes through the former Stafford Beaconside campus of Staffordshire University before hitting a roundabout with the A513, which at this point is named 'Beaconside'. It then heads into Stafford as 'Weston Road', passing around the town centre and heading out along 'Newport Road' and under the M6 motorway towards Telford.
A519	Newcastle-under-Lyme	Newport	At Newport it meets the A518 and A41. It heads broadly north, passing via Eccleshall, junction 15 of the M6 motorway, and then meets the A53 and various other roads in Newcastle-under-Lyme town centre. The road follows the first part of the route of the medieval road from Shrewsbury to York, which passed through the ancient Forest of Lyme. Prior to Tudor times, this was the only major highway from the West Midlands to the North.
A520	Stone	Leek
A521	Meir	Froghall
A522	Uttoxeter	Wetley Rocks
A523	Swinscoe	Hazel Grove	This became part of the A52 (except for the spur in Leek; the current route of the A52 west of there was the A524 at the time), but the changes were undone almost immediately.
A524	Unused		First used from Fenny Bentley to Great Rowsley; swapped with the B5056 around 1970. Used again in the 1990s from Swinscoe to Newcastle-under-Lyme (formerly part of the A52). This almost immediately became part of the A52 again, as the old route of the A52 reverted to the previous designation of A523.
A525	Rhyl	Newcastle-under-Lyme
A526	Woolfall Heath M57 J3	Woolfall Heath A57	Seth Powell Way Originally ran between Newcastle-under-Lyme to Salford; renumbered as a portion of the A34 in 1935. Portions in Manchester are now parts of the A5145, A6010, B5093, and B5117.

Renumbered as an extension of the A5032 in 1935. Used a second time in 1935 for the Barnet Bypass (former A5092 and A5093). After the pre Worboys direction signs were introduced, it was decided to give the route a more unique number to aid navigation, and it became a portion of the A1 in 1954.

A 1932 map does show a proposed A road between Walton, Liverpool and Pendlebury, Salford; this opened in 1934 as the A580, although it is likely it took over at least some of the concept of the A563.
A564	Unused		The original A564 went from the A59 in Liverpool to the A567; rarely appears on maps due to its short length, and as a result it is unknown when the route was decommissioned, but it is now part of the A567. Next used in the 1990s to refer to sections of the upgraded A50 (e.g. from Foston to Etwall) before the A50 was rerouted; became part of the A50 in 1998.

A5077	Unused		Ran from Uttoxeter to the Uttoxeter bypass. After the A50 Uttoxeter bypass was built, the section running through Uttoxeter town center was renumbered: the section running towards Derby was renumbered as an extension of the A518, the section running towards Stoke-on-Trent was renumbered as an extension of the A5077 and the section running along Bradley Street was downgraded. The route is now part of an extended A522.
A5078	Crewe	Site of Crewe Locomotive Works
A5079	Levenshulme	Longsight
A5080	Liverpool	Penketh	May have also been used in Northampton as an upgrade of the B5347. The current number is debatable: A5080 is a duplicate number, and some maps indicate the route as part of the A5095. Official documents favor the A5080 number and signage is completely unhelpful.

A5100	Edgware	Mill Hill Circus	Station Road (Edgware), Hale Lane, Mill Hill Broadway
A5101	Northampton	Northampton
A5102	Stockport	Wilmslow	Shares the same 1 mile stretch of road between Woodford and Bramhall Village with the A5149, where both diverge at each end
A5103	Manchester city centre	M56 J3 near Wythenshawe	Commonly referred to as the Princess Parkway, although this name only applies to the section between the M60 and the M56. The A5103 between the M60 and the city centre is actually Princess Road.
A5104	Corwen	Chester	Was the B5104 before it was upgraded. Originally proposed in 1935 as a renumbering of the eastern end of the A572 between Swinton and Worsley, because it ran parallel to the New Liverpool - East Lancashire Road (the A580). This renumbering never happened, and the route remains the A572. The A5104 was instead used to upgrade a B road with the same number in North Wales.
A5105	Morecambe	Bolton-le-Sands

A5110			Ran from Conwy to Tal-y-Cafn; former sections of B5106 (former B4407) and B5279. Designated after 1954 (not shown on the OS map that year) but before 1957 (first appeared on the OS maps). The sections got their numbers back before 1962 (number not shown on the map that year, but shown with their original numbers). It is not known why the A5110 even existed in the first place, given that one section is narrow and winding in places.
A5111	Mackworth	Spondon	Derby Outer Ring Road
A5112	Battlefield	Shrewsbury	Former portion of the A49. London Road, previously the former A5 between Emstrey and The Column, created when the original Shrewsbury bypass opened in 1933. Renumbered to A5064 in the 1970s when a new relief route was built around the east side of Shrewsbury; this route took over the A5112 number.
A5113			Used for the original route of the A49 after the latter was rerouted further east. It was downgraded to the B5476 in the 1970s.
A5114	A55	Llangefni
A5115	Chester	Church Broughton
A5116	Chester	Moston
A5117	Helsby	Sealand
A5118	Penyffordd	Llong

A5121	Branston	Clay Mills
A5122			Ran from the-then terminus of the A55 (now J11) to the A5 Bangor bypass at what is now A55 J9; route was formerly a portion of the A5 and A487. Now part of the A5 and A487 again when the A55 was extended to Holyhead. Number also used along Farrar Street in Bangor, but is unknown if the two routes co-existed or not, as no number can be identified for Farrar Street when the A5122 was rerouted.
A5123	M1 J15A & A43	Northampton
A5124	Battlefield	Broadoak
A5125	Broad Street in Loughborough	The Rushes Loughborough	May not actually exist; the number does not appear in Leicester County Council documents, but it does appear in DfT traffic count data as well as on OS maps. But even these maps are confusing, as it shows the route running along Ashby Street and Ashby Square before ending at unclassified Swan Street, both narrow one-way streets. Google Maps and OpenStreetMap do not even show the number at all, claiming that the route is part of the A512. Previously allocated to a road from Braunstone to Abbey Park, bypassing Leicester to the east; this was the B583 before it was upgraded. Later became part of the A46 and is now unclassified except the northern end, which is now the B5327.
A5126	Runcorn		"Weston Link" - Links A533 and A557, a part of the Runcorn Expressways system

A5128	Wellingborough	Wilby	Was the A510 and A45 before the Wellingborough bypass was built.
A5129			Ran from the A6 in Kegworth to the A453 east of Isley Walton; originally B5400 when it was upgraded in 1971 or 1972 and rerouted following extension of the runway at East Midlands Airport in the 1960s (the old route crossed the current runway). Except for the eastern end (which is now unclassified), the route is now part of the A453.
A5130	M1 J14	Woburn	Former portion of the A50 between Newport Pagnell and Hockliffe. Declassified in 2017.
A5131			Ran along Saint Margaret's Way in Leicester from the A46 (now A594) to the A6 (now Loughborough Road). Now part of the A6, with the original route through Belgrave declassified.
A5132	Hilton	Swarkestone
A5133			Was a road in Runcorn.
A5134	Elstow	Cardington	Presently being replaced by the Bedford Western Bypass. Originally began at Bronham; the section between Bronham and Elstow was declassified in December 2009 when the A428 Bedford Western and Northwest bypass opened, except for one section that is now the B560 and the section along Woburn Road that is now the B531. Some maps claim that the section east of the A600 is also unclassified.

A5160			Proposed in 1935 to be reserved to form part of a Swindon-East Anglia route together with the A4160 (itself reserved to upgrade the B489 to Class I). But the tonnage was not enough (and likely would never be) on the B489 to upgrade it to Class I, so the proposal fell through. Instead, the A505 was extended over the A601, replacing the A5160.
