Single- and double-digit roads

Road	From	To	Notes
A1	A1211 at Museum of London, City of London	A7 in Edinburgh	Often called the "Great North Road". London sections of road covered by separate A1 road (London) article. May have originally started at St Paul's Cathedral. Longest road in Great Britain. Parts of the road have been reclassified as the A1(M) motorway.
A10	A3 in City of London (The Monument)	A47 in King's Lynn	Section round Cambridge overlaps M11 and A14.
A11	A1211 in City of London (Aldgate)	A147, Inner Ring Road in Norwich	Section between Bow and Stump Cross (M11 J9) superseded by A12 and M11. Section round Newmarket overlaps A14.

A13	A11 in Whitechapel	B1016 in Shoeburyness	Old section of road replaced by A1306 around the Dagenham to Thurrock Bypass. At Canvey Island, road exit is A13, while continuing on current road is A130.
A14	M6, Catthorpe Interchange	A154 at Felixstowe Port	Originally the A14 was the Old North Road, which forms part of the Roman Road known as Ermine Street. It ran from Royston, Hertfordshire through Huntingdon to meet with the A1 south of Alconbury. The Royston-Huntingdon section was renumbered the A1198 to discourage through traffic. The only remaining section of the original 1970's A14 north of Huntingdon, a spur of the A604, was renamed A1307 (along with much of the 1970s A14 road from Cambridge past Huntingdon) following the opening of a second Huntingdon Bypass in 2019.

A106	A107 in Hackney	A12 in Wanstead	Formerly ended at Leytonstone, but according to some maps seems to have taken over bits of the old A11 and A12. Originally, the number referred to the A12 Eastern Avenue section.
A107	A11 in Whitechapel	A503 at Manor House	via Hackney and Clapton. Section between Stamford Hill Road (A10) and Seven Sisters Road (A503) originally B106. The section in Hackney was previously B109 and B110 but became A107 when original route (Mare Street) was pedestrianised.

Secondly, it was used for what's now the A19 from Seaham to Seaton Burn (at the time, the A19 went on the current A1018). It was sometimes an error for Griggs Approach, which was an extension to the A1083. (Griggs Approach was declassified in 2005).
A109	A1010 in Whetstone	A1000 in Tottenham	Westernmost side off A1000 as Oakleigh Road North, becomes Oakleigh Road South, then re-appears off A1003 Friern Barnet Road as Station Road, across the A406 into Bounds Green Road.

A115	Unused		Ran from Hackney Wick to Stratford. Eliminated in 2010; now Chapman Road, Rothbury Road, White Post Lane, and Carpenters Road. The original alignment went from Leytonstone to Valentines, which is now mostly part of the A12, which was rerouted along similar roads.
A116	A118 at Manor Park	A114 at Wanstead	The majority of the route formed part of the North Circular Road until the 1980s.
A117	A116 at Aldersbrook	Woolwich Ferry	Woolwich Ferry Approach forms a small part of the North Circular Road. Originally much more of the route formed the North Circular Road. Meets the A112 head-on at Woolwich Ferry.
A118	A12 at Bow	A12 near Romford	Section between Bow and Stratford was A11, with the section east of Stratford forming the original A12. An older one went from Canning Town to Rippleside. This is now part of the A13 (which the old route became an extension of the A124 and A123).

A123	A113 at Chigwell	A13 at Lodge Avenue, Barking	East of Barking town centre (Ripple Road) was the original A13. A13 still uses much of the original (albeit dualled) Ripple Road towards Dagenham.
A124	A13 at Canning Town	B187/B1421 in Upminster	Western section was the original A13 as far as Barking. Originally ran from the A13 in Barking and terminated on A125.
A125	A12 North of Romford	A1306 (former A13) at Rainham	Section at Roneo Corner overlaps with A124. Section in the Romford Ring Road overlaps with A118.
A126	A13 at West Thurrock	A1089 in Tilbury	At junction with A13, only west facing on/off slips are provided. Some maps show A126 continuing to A1089 beyond Dock Road. Originally terminated at Tilbury Riverside Station where a road ferry crossed the Thames to Gravesend. This ferry still runs but for foot passengers only.
A127	A12 at Romford	A13 at Southend	Known as the Southend Arterial Road. Via Basildon; part of the eastern end was A1015. Originally built as single carriageway with provision for dualling later.
A128	A13 at Orsett	A414 in Chipping Ongar	used to run from Tilbury and end on A113. Route from Tilbury now A126 and unclassified.
A129	A1023 near Shenfield railway station	A13 at Hadleigh	Eastbound traffic in Billericay has to use A176 (unsigned) to resume journey on A129. Northbound traffic on the A132 in Wickford wishing to join the eastbound A129 where it multiplexes with the A132 requires a u-turn at the next roundabout.
A130	A12 at Howe Green, near Chelmsford	B1014 at Canvey Island	Used to start at Trumpington, near Cambridge. Originally ended on the A129 near Rayleigh until extended to the A127 and then Canvey Island. In 2008 from Dunmow to Chelmsford the road was downgraded to B1008.
A131	A12 at Boreham Interchange, near Chelmsford	A134 at Sudbury	Much of the one-way system in Sudbury, now the A131, was originally the A134 before the bypass opened. Recently, it replaced the A130 between Little Waltham and Chelmsford.
A132	A13 in Pitsea, Basildon	B1012 near South Woodham Ferrers	Originally allocated to the road from Colchester to Huntingdon (became part of A604, now A1124, A1017, A143, A1307, A14). Current route overlaps with A129 at Wickford.
A133	A1124 (former A12) near Colchester	Clacton-on-Sea, sea front	by way of Elmstead Market, Frating, Great Bentley and Weeley (Main route uses a bypass at Weeley). Has a spur from A12 to A120 at Hare Green. To the East of Hare Green, crosses former A604 (now unclassified). The Colchester bypass was originally the A12 and later became the A604. Continued north to Sudbury from 1929 to the 1970s via what is now the B1508.
A134	A10, south of King's Lynn	A133 in Colchester	Although this road forms the Sudbury bypass, it's the route through the town centre (A131) which has primary status. A spur of the A134 near Stradsett used to link to the A1122 (former A47) at Crimplesham. Later unclassified, this spur is still heavily used to avoid the awful staggered junction with the A1122 at Stradsett a little further north.
A135	A1130/A1305 Ring Road in Stockton-on-Tees	A67 at Egglescliffe	Originally this number belonged to the road from Colchester to Harwich via Manningtree in Essex; this became part of the A1124 and the A604, and is now shared between the A137 and, east of Manningtree B1352. Traffic from Colchester to Harwich is now directed via the A120. The current A135 follows part of the original route of the A19.
A136	A120 in Harwich	Harwich International Port	Originally this ran from Harwich to Clacton. This extended east to Harwich town later where there is another international port. Later, the section southwest of Harwich became part of an extended B1414. Later, this extended north to Parkeston Quay, west of Harwich. The section from the A120 to Harwich Town was later declassified (it is now Parkeston Road and the B1352), leaving the current section from the A120 to Parkeston Quay (Which was later rerouted on the bypass; the old route is now Station Road).
A137	A1214 (former A12) in Ipswich	A133 in Colchester	This road connects the town centre of Ipswich to Old Stoke by going over the Old Stoke Bridge which traverses the tidal section of the River Orwell.[1] Alton Water reservoir covers part of the former route of the A137 at Tattingstone White Horse.
A138	A12 east of Chelmsford	A1114 near Chelmsford city centre	Partly follows first Chelmsford city centre bypass. One-way eastbound between A1114 and first roundabout. Called Chelmer Road. Previously allocated to a road between Ipswich and Shotley Gate (now B1456).
A139	A1305 Ring Road at Stockton-on-Tees	A19 south of Billingham	Previously allocated to a road between Ipswich and Felixstowe where a road ferry crossed to Harwich. (This became the A45 before the bypasses opened. Note the current A14 (ex-A45) uses none of the former route of the A139.) Only south facing slips are provided at the A19 junction. Traffic must use the A1027 to access the northbound A19.
A140	A14 east of Needham Market	A149 near Cromer	part of original route occupied by Norwich Airport runway. Originally started on the then A45 in Claydon and followed current A14 to present starting point.
A141	A47 at Guyhirn	A1 & A14 Brampton Hut	Originally started on the A17 in Kings Lynn and continued to its current starting point at Guyhirn. When the new bridge opened over the River Ouse, the A141 swapped routes with the A47 between Wisbech and Guyhirn. Subsequently, the A47 was diverted onto a new alignment with the former A141 being downgraded to the B1441. This road was later declassified, but was upgraded to the B1542 in 2020.
A142	A141 at Chatteris	A1304 (former A11) at Newmarket	Used to pass under very low (2.7m) bridge at Ely but diverted on to southern bypass which opened in 2018. Previously met A10 at Ely Cathedral.
A143	B1370 at Gorleston on Sea, south of Great Yarmouth	A1017 at Haverhill	Originally started on A12 (now A47) in Gorleston and ended in Bury St Edmunds. Extended along course of B1060 to the A604 in Haverhill. However, in the 1990s, the A604 was downgraded with the A143 taking the route of the former A604 to end on the bypass.
A144	A12 at Darsham	A143 at Bungay	Originally continued to Norwich, the Bungay-Norwich section since renumbered B1332. Passes former RAF Halesworth which is now owned by Bernard Matthews.
A145	A12 at Blythburgh	A146 on Beccles bypass	Originally started in Bungay and ended as now on the A146 but ran via a different route along the East bank of the River Waveney. The road was extended to Blythburgh by the 1930s, when the original section was renumbered the A1116 (now mostly the B1062) to dissuade its use as a through route.
A146	A140, Outer Ring Road in Norwich	A1117 in Lowestoft	Originally ended on A12 in Lowestoft.

A152	A52 in Donington	A16 at Surfleet	Originally terminated on A16 east of Gosberton. Extended to current terminus when the new section of A16 opened in the 1990s. Originally continued west via current A52 to A1.
A153	A607 bypass at Honington	A16 bypass at Louth	Originally passed through Sleaford on the current B1517. At Tattershall, the original river bridge remains but is closed to traffic.
A154	A14 north of Felixstowe	A14 Felixstowe docks	The original alignment went from Mablethorpe to Donington (originally ended in Swineshead) with a spur to Swineshead (now the A52). The current A154 is the original route of the then A45 into Felixstowe, although the final section by the river has been lost to redevelopment.

A158	A15 in Lincoln	A52 in Skegness	Follows former Roman road from Langham to Lincoln. Originally started at A154 (now part of the A52) by Skegness railway station. Section of route towards Lincoln was originally the A157 but then became part of an extended A158 which also used the current A15 route to end on the former A15/A46 junction near Pottergate.
A159	A18 in Scunthorpe	A631 & A156 in Gainsborough	The route in Gainsborough as far as the junction with the B1433 is the original route of the A631. Used to continue into Scunthorpe town centre along now unclassified road. Crosses M180 motorway but without a junction.
A160	A180 at Ulceby, North Lincolnshire	A1173 at Immingham docks	Previously allocated to a road between Croxton and Barrow upon Humber. This road was rerouted via Ulceby to Immingham Docks in 1969, with the old route becoming an extension of the A1077. When the current route was built, the old route became an extension of the A1077 (which was diverted away from the centre of Wootton) and the B1211. About 1 mile long.
A161	A631 on Beckingham bypass	A614 at Goole	Originally this road continued west to Rawcliffe, but the A614 replaced that section when it was rerouted. The section from Beckingham to the A18 near Crowle was originally the B1187 but was upgraded in 1932.
A162	A1(M) at Darrington (Junction 40)	A659 (former A64) at Tadcaster	Although the road commences on the A1(M) there is no connection between the two. The A162 follows the route of the original A1 as far as Ferrybridge. The old A1 continues ahead as the A1246 with traffic for the A162 having to use slip roads. Originally started on former A1 at Brotherton.
A163	A19 near Barlby on Selby bypass	A614 in Holme on Spalding Moor	Originally, this road continued northeast to Driffield, but that section became part of the A614 in 1996.
A164	A15 in Hessle	A614 at Driffield	Originally started in the centre of Hull and used the current B1231 and an unclassified route via Kirk Ella and Willerby. The current route came into use with the opening of the Humber Bridge and Clive Sullivan Way. Used to pass through Beverley and terminated on the A166 in Driffield town centre. Some maps also mark the A164 as continuing to the A63.
A165	A1079 in Kingston upon Hull	A171 north of Scarborough	The non-primary section near Scarborough was the B1262 until the 1920s. Used to pass through Osgodby (near Filey) but that road is no longer open to through traffic south of the village. (A bypass for another village called Osgodby in Yorkshire on the A63 was intended to be built at the same time but this never happened.)
A166	A64 at Grimston Bar, York	A614 on Driffield bypass	Continued to Bridlington until 1996 when the A614 was extended over the Driffield to Bridlington section. Until the opening of the York bypass (A64), started on A66 (later A1079).

Includes A167(M), the only section of urban motorway built as planned in Newcastle. The section through Newcastle was previously A6127 and A6127(M). Maps show the A167 having two arms north of Gosforth, one towards Westerhope and the other to Kenton. However, only the road towards Kenton is signed.
A168	A659 at Boston Spa	A167 at Northallerton	Originally started at Thirsk but expanded south when the A1(M) opened, using one of the carriageways of the former A1. There is a dispute about whether the dual carriageway section known as the Dishforth Spur is part of the A1(M) or the A168(M). A minor detour south of Boroughbridge was a temporary terminus of the A1(M).
A169	A64 bypass at Malton	A171 west of Whitby	via Vale of Pickering. North Yorkshire Moors Railway follows more or less the same route between Pickering and Whitby. Used to meet A171 at Bagdale but was diverted after the river bridge on the route was washed away in the 1930s. Further changed when Whitby bypass opened in 1972, the A171 taking over the A169 route into Whitby as part of the bypass.
A170	A19 & A168, south-east of Thirsk	A171 & A64 in Scarborough	via Sutton Bank, a 1 in 4 climb in the North Yorkshire Moors. Via Beadlam, Pickering and Thirsk town centre, the latter following the alignment of former A19.

Non-primary section between Lazenby and Whitby known as 'The Coast Road'. The modern viaduct near the Skinningrove steel works replaced the original Victorian viaduct as part of improvements to the A174.

Section north of A691 was declassified (a portion became the B6532 later). Section from A691 to A690 became an extension of the A691 (which was rerouted on Framwellgate Peth a few years later), truncating the road to the A690. Later rerouted on the New Elvet Bridge. Rerouted on its current route in the 1990s, replacing portions of the A1051 and A1050.
A178	A66 in Middlesbrough	A689 near the harbour in Hartlepool	Crosses the transporter bridge in Middlesbrough. The road between Seaton Carew and Port Clarence was originally a private toll road built by the Tees Concervancy Commission in January 1919 which was only open during daylight hours.

Passes over roof of Hatfield Tunnel.
A1002	Unused		Ran from A10 to A503 in Tottenham. (Became part of the A10 one-way system (which was later rerouted onto Monument Way rather than Chesnut Road) and is now part of the A503; at the time, the A503 followed Broad Lane)

A1011	A112 in West Ham	A1020 in Silvertown	Portion east of A1020 is now part of A1020. Passes West Ham Station and under the Northern Outfall Sewer in Manor Road. The Greenway walkway lies on top of the sewer.
A1012	A13 in North Stifford	A126 in Grays	There is confusion as to whether the section after the Elizabeth Road roundabout is part of the A126 or A1012. Maps suggest that this is also the A1012 but signage suggests this is the A126. (The A126 originally didn't have a northern deviation in Grays but followed the railway line direct into Grays.)
A1013	A13 near Stanford-le-Hope	A126 in Grays	Former A13 alignment (pre-1980s) between Stanford and Lodge Lane, Grays. The section between Lodge Lane and Grays town centre was the original alignment of the A1013. Lodge Lane between A1013 and A1306 is presently unclassified but was part of the A13 until the 1980s. Locals commonly call this road the "old A13".

A1017	A1307 in Haverhill	A131 north of Braintree	via Gosfield, Ridgewell. Originally ran from A131 to current A1124, most of the rest being the A604.
A1018	A194/A183 in South Shields	A19 near Seaham	Former A19 alignment; a former alignment went along the old A1 through Grantham (now B1174), and the original alignment went from A137 west of Manningtree to Mistley (became A137 spur, now B1352 spur). Part of the route in Sunderland was the B1522 and B1294 prior to the opening of the Sunderland Southern Radial Route and the route is still signed as such at some points, even though the new road opened in 2008.
A1019	A414 in Harlow	A1025 in Harlow	The original A1019 went from Harwich to Parkeston (became part of the A604, later part of the A136, now Parkeston Road and Station Road). Passes Harlow College.
A1020	A13 at East India Docks	A406 in Beckton	The original A1020 went from Great North Road (then the A1) to Crosshall Road (then the A45) in St Neots via St Neots Road. Should the proposed Silvertown Tunnel be built, then the section west of the A1011 junction would become part of the realigned A102. Part of the North Circular Road. An unused bridge just after the A117 junction was intended to link to a new bridge across the Thames. This was cancelled by the then Lord Mayor, Boris Johnson.
A1021	A154 in Felixstowe	A154 in Felixstowe	Formerly part of the A139, the original route into Felixstowe. Previously allocated to a road from Buckden, Cambridgeshire to Brampton (became part of the A141, now a spur of the B1514).

Part of Ipswich Inner Ring Road.
A1023	A12 Brook Street Interchange (Brentwood)	A12 J12 near Mountnessing	Former A12 alignment. Previously allocated to a road from A47 to A134 in Crimplesham (now Main Road). Partially follows course of Roman road. Via Brentwood.
A1024	A1042, Mile Cross in Norwich	A1074 Dereham Road in Norwich	The section from the A1074 to King Street (the original section) was mostly replaced by the A147, but Earlham Road section is now the B1108 and the Heigham Road section is unclassified.

Construction of M11 Junction 7A has seen the A1025 replace a section of the B183 between the A414 and the roundabout junction onto the new M11 link road.
A1026	Unused		Ran along North Quay and Fuller's Hill (now part of the B1141) in Great Yarmouth from the A12 (now A1243) to the A47 (now Northgate Street). May have been used in Ipswich between the A12 and A1114; this is now part of the A1156.
A1027	A135 in Hartburn	A139 in Billingham	Previously allocated to a road along Chapel Road in Wisbech. This was redesignated as the B1442 when the A47 was rerouted off of North Brink and Barton Road (which became the B1441), and became the C313 when the B1441 became the C312. Has only existed since 1968 when previously unclassified roads Hartburn Ave, Oxbridge Ave and Bishopton Avenue were upgraded to A road status. Extended in 1974 following opening of new roads carrying the A66 and A19. Yarm Road South previously part of A135.
A1028	A16 at Ulceby Cross	A158 in Candlesby	via Ulceby
A1029	A1077 in Scunthorpe	A18 in Scunthorpe	Previously ended on A159 in town centre. Part of the northern section was the A1077.

Crosses Newport Bridge, a lift bridge which is now locked in position but with the lifting mechanism still in place.
A1033	A1079 in Kingston upon Hull	B1362 in Withernsea	via Hull, Thorngumbald, Patrington. Originally started on A165 in centre of Hull and ended in Hedon.
A1034	A63 on South Cave bypass	A1079 on Market Weighton bypass	Partly follows course of Roman road. Originally started in centre of South Cave village and ended on A66 in centre of Market Weighton.
A1035	B1242 at Hornsea	A1079 near Beverley	Formerly started at A165 at Leven but extended when B1244 was reclassified as A1035 in 2013.
A1036	A64 near Copmanthorpe	A1237 near Huntington	Originally assigned to Low Petergate, Colliergate, Fossgate and Walmgate through downtown, but was shifted to the eastern half of the inner ring road when that was built. (Entire inner ring road now part of A1036). The remainder of the route is the A64 through York prior to the York By Pass.
A1037	A112 in Chingford	A1009 in Chingford	Created in the 1980s. Known as Waltham Way, runs alongside the River Lee Diversion and William Girling Reservoir. Previously allocated to a road from the A165 east to Manor Street in Bridlington (now part of the A1038).

A1040	Unused		Ran from the A174 north to downtown Redcar; renumbered to B1269 in 1984.
A1041	A614 in East Cowick	A19 in Selby	Previously allocated to a proposed road from Middlesbrough to Redcar, but this was opened as the A1085 instead. The A1041 was instead allocated to a road between Goole and Holme-on-Spalding-Moor (this became part of the A614 which also replaced part of the A161 from Goole to west of Rawcliffe, and the A1041 was reassigned to the old route of the A614).
A1042, (Norwich)	A140 in Norwich	A47 in Norwich	Duplicate number which first appeared in 1992. Part of Norwich outer ring road which used to run down now unclassified Harvey Lane. The easternmost section was part of the A47 until that road was moved on to a new southern bypass in 1992.
A1042, (Redcar)	A174	A1085 near Redcar	This route was first designated in 1924 and connected Kirkleatham and Redcar High Street meeting the northern end of the A1040. It was subsequently extended from Redcar to Marske along part of the current A1085.
A1043	A171 in Nunthorpe	A172 in Nunthorpe	Nunthorpe Bypass. Originally passed through Nunthorpe.
A1044	A67 (former A19) in Yarm	A174 near Thornaby	Originally went northeast along what is now the B1380 between what was previously the A1045 to the A174 at Hemlington. (Some maps still show the A1044 along this section which was downgraded in 2000.)
A1045	Unused		Ran from Thornaby-on-Tees to Stockton-on-Tees (now A1044 and Thornaby Road; the A1044 went northeast on what is now the B1380).
A1046	A1305 in Stockton-on-Tees	A178 in Port Clarence	Originally started on Stockton High Street (the former A19). Via High Clarence.

A1048	A1049 in Hartlepool	A179 Marina Way in Hartlepool	Originally started in centre of West Hartlepool where the other three roads at the crossroads were the A178, A179 and A689. This section is now unclassified following construction of Marina Way.
A1049	A179 at West View, Hartlepool	Northgate Town Square, Hartlepool	Originally started in centre of Hartlepool on A179.
A1050	Unused		Ran from Farewell Hall to Durham (now A177/South Road and Church Street)
A1051	Unused		Ran from A177/Hallgarth Street to Crossgate (now A177, Quarryheads Lane, and Margery Lane)
A1052	A183 in Houghton Gate	A690 in Houghton-le-Spring	via Fence Houses, High Dubmire
A1053	A174 near Lazenby	Grangetown	Previously allocated to a road from Chester-le-Street from Newcastle Road (then the A1) to Picktree Lane (then the A693, which went west via Pelton Lane); this became part of the A693, and later, when the Chilton bypass was built, also became part of the A167. Ends at Teesport security checkpoint where the only way of turning around is on the roundabout beyond the checkpoint, even though signs indicate this to not be used by the general public.
A1054	A146 in Norwich	A147 in Norwich	Previously allocated to a road from the A19 (now the B1285) east to Seaham (now the B1404 and B1287). Although most maps indicate that Bracondale is a spur of the A147, others claim this road, which was originally part of the A146, is now part of the A1054. (Signs on the ground do not indicate either is correct.)
A1055	A503 in Tottenham Hale	A10 in Waltham Cross	Previously allocated to a road from the A184 east of Gateshead to the A185 in South Shields (now part of the A194). A spur of the A1055, called Conduit Lane, connects the A1055 to the A405 which the main route passes underneath without a junction. The unclassified road at the A10 junction was originally part of the A105.
A1056 (Northumberland)	A1 J79 near North Brunton	A19 near Killingworth	via Wideopen. Sandy Lane was originally part of the B1318. The section between the B1505 (former A189) and A19 was intended to be dual carriageway but only one carriageway has been built.
A1056 (Norwich)	A11 in Norwich	A140 & A146 in Norwich	Previously allocated to a road from A185 in Jarrow via Monkton Terrace (later closed), Grange Road, and Staple Road/Ferry Street to the dock, where the ferry ran. The current Norwich A1056 was created when the A140 was rerouted on to the Outer Ring Road in the 1990s.
A1057	A1001 on Hatfield bypass	A1081 in St Albans	Previously allocated to a road in Newcastle upon Tyne from A695 (this section now part of the A186) via Pilgrim Street and Northumberland Street to the B1318 (then part of the A1). The current A1057 was originally part of the A414. The B6426 in Hatfield was the original route of the A1057 but was also originally part of the A414.
A1058	A167(M) in Newcastle upon Tyne	A193 in Tynemouth	The spur of the A167(M) could be the A1058(M) instead as signs on the spur are blue with the designation A1058. Originally started on A1 Barras Bridge and ran along Jesmond Road. Partly occupies former route of A188. Original terminated by railway station on A193 in Tynemouth running along Queen Alexandra Road and King Edward Road but these are now unclassified.
A1059	Unused		Ran from London Road (this was then A1184, but now B1383) to A1250 in Bishop's Stortford (now South Street, Potter Street, and North Street, with southbound traffic going on Dane Street and Station Road; now the B1529). Previously allocated to a road from Gosforth to Longbenton (now part of the A191).
A1060	A1250 in Bishop's Stortford	A12 near Sandon	Previously allocated to a road from Longbenton to West Moor (now part of the A188, which previously went northeast via the current A191 routing and A186 routing to the A192). Via Little Hallingbury, Hatfield Heath, "The Rodings" and Chelmsford. Originally the B1005 and A414.
A1061	A189 in Shankhouse	A193 in South Beach, Blyth	Originally A192 to A189 near Cramlington. The A189 now occupies part of the original route while a farm track south of the current route was also part of the original A1061. Part of the current route around New Delaval used to be part of the B1237.
A1062	A1151 in Hoveton	A149 east of Potter Heigham	Previously an eastward continuation of the B1354. Previously ended on A149 in centre of Potter Heigham. Previously allocated to a road from Bebside to Bedlington (now part of the A193)
A1063			Ran from Wendens Ambo to Saffron Walden (replaced the southernmost section of B1052, but became part of the B1052 again when the M11 was constructed). Previously allocated to a road from Morpeth to Guide Post (now part of the A196; at the time the A196 went south via the current A1068 to the A192).
A1064	A47 Acle bypass	A149 Near Caister-on-Sea	Originally Beach Road in Caister-on-Sea, later extended to Acle, but the section on Norwich Road and the original section on Beach Road was declassified when the A149 was rerouted. Entire route was part of A47 until 1935.
A1065	A11 in Mildenhall	A148 near Fakenham	Lakenheath airfield occupies part of former route where the road bends sharply. Via Brandon and Swaffham. Prior to 1922 was part of the B1105.
A1066	A11 near Thetford	A140 east of Diss	via The Forest, Garboldisham, Roydon and Diss. Passes Bressingham Steam Museum. Created in 1924 when the Thetford to Diss section of the B1111 was upgraded. The short section of route east of Diss to Sluston Common was originally part of the B1131 which ended on the now unclassified original route of the A143.
A1067	A1042 (former A140) in Norwich	A148 near Fakenham	significant portion is now B1454 between Tattersett and Heacham via Docking. Signage in Norwich suggests it starts closer to the A147 at the junction of Pitt Street and New Botolph Street but mapping suggests otherwise. From the 1920s until the construction of RAF Sculthorpe, the A1042 ran along the entire route of the B1154 ending on the A149 in Heacham. This extension was downgraded to the B1454 in the 1960s. Note that the site of the junction of the A148 and B1154 lies under the runway.
A1068	A1 at Seaton Burn	A1 south of Alnwick	via Bedlington, Guide Post, Widdrington and Amble. Originally passed through Red Row and Broomhill and ended on A1 on edge of Alnwick town centre. Partly occupies route of original B1337, B1336 and B1333.
A1069	A110 in Chingford	A104 (former A11) in Buckhurst Hill	Passes Chingford railway station. Via Epping Forest.
A1070	A1072 in Stevenage	A602 in Stevenage	Previously allocated to a road from the A12 (now the A1124) in Colchester to the A133 in Greenstead (this became the B1422, and is now part of the A134). Another disputed A1070 was on Fairland Way in Stevenage (the current A1155). Just before the A602 roundabout a grassed over bridge carrying a cycle path can be seen on the left. This bridge was once part of the A1.
A1071	A134 southeast of Sudbury, Suffolk	A1214 near Ipswich Hospital	via Hintlesham and Ipswich. The original A1071 took over the route of the B1069 and ran along Hadleigh Road ending on the original A12. The gap in continuity in the town centre stems from the A45 being diverted along what had been originally the A12 and A139 in 1935. When the A45 was diverted on to the bypass (current A14), the A1071 was extended to its current terminus.
A1072	A602 spur in Stevenage	A1175 in Stevenage	Previously allocated to a road from Witcham Toll to Stretham (the east–west section became part of the A1123, while the north–south section became a spur of the A1123, and is now the A1421).
A1073	Unused		Ran from Eye to Spalding. It was downgraded to two C-roads, because the bypass was open, but the new bypass became part of the A16 road, while the old route of the A16 became the A1175.
A1074	A47 at New Costessey	A147 in Norwich	Previously part of the A47 prior to the construction of the Norwich southern bypass; formerly used on the Norwich Outer Ring Road. The original A1074 was from the current A1074 (then part of the A47) north to what is now the A1402 (became an extension of the A1024).
A1075	A1066 in Thetford	A47 near East Dereham	Previously allocated to a road from Donington to Baythorpe (became part of the A154, now the A52). The A1075 was an upgrade of the B1110 and has been extended along the former A11 through Thetford town centre. Note the original alignment of the B1110 between Thetford and Hatton was requisitioned by the army in 1942 as part of the Stanford Battle Area with the B1110 diverted on to previously unclassified roads.
A1076	A148 in Gaywood	A149 in Kings Lynn	Previously allocated to a road from Gunness to Scunthorpe (now part of the A18, which at the time went east from Gunness via what is now the B1450). The current A1076 was originally part of the B1145 and was upgraded when the bypass opened. Some signs still indicate this route as the B1145.
A1077	M181 near Scunthorpe	A160 in South Killingholme	Originally started in centre of Scunthorpe where the other roads were the A1076 and A1029. Via Risby Warren, South Ferriby, Barton-upon-Humber, Barrow-upon-Humber.
A1078	A148 in Kings Lynn	A148 in South Wootton	Previously allocated to a road from Guide Post to west of Ashington (now part of the A1068). Passes the docks.
A1079	A1036 inner ring road in York	A63 near Kingston upon Hull	Newland Avenue in Hull has a pub alongside a railway bridge made from part of a former railway carriage. Passes close to the University of Hull. Originally passed through Beverley along a now unclassified road. Via Bishop Burton, Shiptonthorpe and Hayton. The entire route is part of the pre-1922 route of the A66.
A1080	A105 at Turnpike Lane Underground station	A10 at Tottenham	Formerly numbered as part of the A108; the original route went from the A11 (now Broadway) to the A12 (now Broadway) in Stratford (now a spur of the A118/The Grove). Traffic on the A1080 can only turn on to the northbound A10 in Tottenham.
A1081	Luton Airport	A1000 in High Barnet	Previously allocated to present A1400 and A406 from Gants Hill to Walthamstow Forest. This road was originally the A6. Its actual numbering is curious because it is out of zone although it may be due to the rerouting of the A1 and curtailment of the A6 in the 1950s. Maps but not signs indicate the A1081 continues through the tunnel under the airport.
A1082	A148 south of Sheringwood	A149 at Sheringham	Previously numbered as the B1158; original location was on what is now the western half of the Whipps Cross Roundabout. Shortly after the junction with the A148 is a turning on the right which was the original route of the B1158, the current route being created when the road was upgraded to A road status.
A1083	A124 in Becontree Heath	A118 in Ilford	Originally the B176, it was extended along Griggs Approach, a new bridge across the railway line, in 1985 but this was downgraded to unclassified in 2005.
A1084	A18 (originally A15) near Brigg	A1173 near Caistor	Originally the B1209, it used to end on the A46 in Caister town centre but was extended along Grimsby Road to its current terminus when the A46 bypass opened.
A1085	A172 in Middlesbrough	A174 south of Marske-by-the-Sea	Most of this road wasn't built until the 1920s. During construction of the Middlesbrough to Redcar section it was designated as the A1041 but was numbered A1085 upon opening. However the route was subsequently changed with the westernmost part becoming the A172 and the A1085 diverted to run past Albert Park. This was later declassified but the B1272 still ends on the Albert Park route.
A1086	A19 in Easington	A179 in Hartlepool	This road was built in the 1920s and was allocated the number A180 in the 1922 roads list. However, none of the A1086 has ever actually been the A180. The original route was as now from the A179 but in West Hartlepool and ending on the B1283 at Easington Colliery. In more recent times, the A1086 in Easington has swapped routes with the B1283. The connection to the A19 was originally a spur of the A182.
A1087	A199 in Beltonford	A1 near Broxburn	Numbered B1345 until late 1920s. Originally started on A1 rather than A199, the change being made as part of the upgrade of the A1. Via Dunbar (which the A1 has always bypassed) and John Muir Country Park.
A1088	A14 J47 east of Woolpit	A1066 in Thetford	Originally the B1112, it was upgraded in the 1920s. It mostly follows the boundary between Norfolk and Suffolk. Passes through the village of Euston. The local peer also owned land in London and named the area around what is now the A501 after this village. Originally met the A143 in Ixworth town centre but both roads now bypass it, part of the old A143 being closed to traffic. A layby near Stowlangtoft once formed a hairpin bend on the route. The road originally ended on the original A45 west of Woolpit.
A1089	A13 at Orsett Heath	Tilbury Cruise Terminal	this is the Trunk Road into Tilbury (and not the A13!) Previously allocated to the current B149 from Little Thurrock to Chadwell St Mary. The unclassified road heading east towards Tilbury at the A126 roundabout was originally a continuation of the A126. (It was downgraded with the removal of the A128 from the Tilbury area.)
A1090	A1306 near Purfleet	A126 in West Thurrock	Created in 2013, when the old A1090 along New Tank Hill Road and London Road in Purfleet was declassified. The Purfleet bypass was originally the A126 but became unclassified when the A126 was diverted to the current A13 in the 1990s.
A1091	Unused		Originally the B1006, it ran along Lordship Road in Writtle from A414 (now A1060) to Ongar Road (then the A122). Became a part of the A414 between 1978 and 1982, but was downgraded in 1986 following general renumbering around Chelmsford after the bypass opened.
A1092	A1017 in Baythorne End	A134 Long Melford	Originally numbered B1062, the road originally ended in the centre of Long Melford on the A134, both forks either side of the village green being the A1092 at that time. The current A1092 only uses the left fork, the main route ahead is the B1064.
A1093	Unused		Originally the B1080, it ran from Main Road (then part of the A12, which went west via the current A1214) in Martlesham to west of Kirton (now Felixstowe Road, Gloster Road, Barrack Square, and Brightwell Road)
A1094	A12 near Stratford St. Andrew	Aldeburgh	Originally ended at the Moot Hall, Aldeburgh and designated B1121, it was extended to its current terminus in the 1920s.
A1095	A12 near Blythburgh	Market Square in Southwold	Originally part of the B1123. The unclassified continuation of the route in Southwold, Queen Street, leads to the ferry across the River Blythe. This ferry service was once a vehicle ferry but now is foot passengers only.
A1096	A1123 at Galley Hill	A1307 (former A14) near St Ives	Previously allocated to a road from Acle to Great Yarmouth (now part of the A47; at the time the A47 went via the current A1064 and A149 to Great Yarmouth). Most of the route was part of the B1040 (which now multiplexes along the entire route) and was upgraded in the 1970s including a new bridge in St Ives.
A1097	Defunct		Running between A157 (now B1200) and A16 (now B1502), it directed traffic heading between the west and the north away from Louth town centre along St Mary's Lane. Downgraded in 1991, when the Louth bypass was opened, to become a spur of the B1200.
A1098	A16 in New Waltham	A46 & A180 in Cleethorpes	via Cleethorpes sea front. When first opened in the 1920s, passed through New Waltham along current B1198.
A1099	A1060 in Chelmsford	A1060 in Chelmsford	Partly uses a section of the former A12, Springfield Road.
