Upgraded to a portion of the A4201, but that was later rerouted onto the parallel Portland Place instead of Great Portland Street, returning it to Class II status, but it became the B506 instead of the B505. The section along Mortimer Street is now part of the A5204.
B506
Marylebone Road
Russell Square
Great Portland Street and Mortimer Street east of Regent Street. Originally ran between the A5 and A400 (paralleling the A40), with a multiplex with the B505 at the western end of Mortimer Street. The B505 was upgraded to the A4201, and the section of B506 west of the B505 was also upgraded, probably to the A5204. The B506 was extended along the old route of the A4201 when it was rerouted along Portland Place. The remainder of the original B506 is now part of an extended A5204. The original route was also extended further east and when that became the A4201, the extension remained, dividing the route into two sections.
Liverpool Road. Passes through residential Islington. As this road is an alternative to the A1, it attracts rat-runners, therefore a 20 mph speed limit has been introduced throughout with traffic calming (speed humps) to enforce it.
Much of route now part of the southbound route of the A400; the section along North Gower Street is now unclassified and its northern end closed to traffic.
Runs through North Hendon and Mill Hill Village, runs along the A5109 for a short while at Highwood Hill, then up Hendon Wood Lane to Arkley.
B553 (defunct)
A5 in Edgware
A1 in Whetstone
Upgraded to the A5109, likely in the 1940s.

A411 at Barnet Gate
Renumbered as a northern extension of the B552.
B555 (defunct)
A5 north of Radlett
A414 in Hatfield
Section between Colney Heath and Hatfield became the A5092 (later A555, now A1) in 1926 when the Barnet bypass opened. Renumbered to B556 in 1935, probably to avoid confusion with the Barnet bypass which was given the A555 number.
Previously ran between Dunstable and Ampthill (partially now A5120).
B557 (defunct)
A5 near Fenny Stratford
A6 in Bedford
Section north of the M1 became the A5140 (later A421, now C94), the section along the Bedford bypass became a portion of the B531 and the section south of the M1 was declassified with the growth of nearby Milton Keynes.
Except for the easternmost end, it was renumbered B562 (later A5134) in 1935. The easternmost end (which was never upgraded to an A road) is now part of the B531. After this section of the A5134 was downgraded in 2009 due to construction of the A418 Bedford western bypass, the route west to Kempston Church End became the B560 and the remainder declassified.
B563 (defunct)
B557 in Bedford
A6 in Bedford
Upgraded to Class I status as the A5141.
B564 (defunct)
B563 in Bedford
A6 in Bedford
Declassified; the eastern half is now pedestrianized.
Originally classified as "Barwell Fields - Earl Shilton", connecting the A447 and A47 through Barwell to the north of Hinckley, and was extended to Dunton Bassett in the mid-1920s. By 1932, the original section was upgraded to Class I status as the A5096, but was downgraded again in the 1960s, likely returning to the B581. The section west of the A47 Earl Shilton bypass (including the entire original section) was declassified after the bypass was built and is now a dead end after Elmsthrope Lane was split by the bypass.
Originally started further south on the A447, at Osbaston Toll Gate and ran east to meet the B585 on the edge of Newbold Verdon (this is now unclassified) and originally continued to the A47 in Thurnby (a portion of this is now the B568).
B583 (defunct)
A46 (now A5460) in Leicester
A6 in Leicester
Upgraded to Class I status in the 1960s as the A5125 (later A46). Declassified after the A46 was rerouted, but the northernmost section is now part of the A6 and the section north of the A50 is now the B5327.
B584 (defunct)
A444/A5 in Caldecote
A483 near Measham
Section south of Twycross became a northern extension of the A444 and the northern section became the B4116.
Originally ran along Broad Street from the A512 to the A6, but this was declassified around 1980. The current B589 follows the former A6004 on the wrong side of the A6, putting the B589 out-of-zone.
B590
Rugby Road in Hinckley
Rugby Road in Hinckley
Inner town loop around Hinckley; one section is former B5402.
Rerouted; incorporates sections of former B5330 and B5350. Formerly: east (from near Copt Oak) to A6 at Quorn, Leicestershire, and west from A50 to Ibstock and beyond; both these sections now unnumbered classified roads.
Former routing of the A5. Originally ran from the A516 in Hilton to the A514 in Swarkestone; this was upgraded to the A5132 between January 1969 and 1971.
Originally ran from the B5012 south along Chasetown High Street and Hanney Hay Road to the A5; the section past Triangle was rerouted by 1928 along Ogley Hay Road to the A5 at Middleston Bridge. Around 1986 the B5011 was extended south of the A5 to the A452 in Brownhills. This now out-of-zone section is all that remains of the B5011 as the section north of the A5 was declassified (and replaced by the A5195) due to completion of the M6 Toll.
Only 1 km long; formerly the B5019. Originally ran between the B6000 and A516 in Derby city center; now unclassified and partly pedestrianized, as it is completely inside Derby's inner ring road.
Originally continued to the A6; this is now part of the A5012.
B5037 (defunct)
B5028 in Dresden
A50 near Normacot

Originally ran along Wharf Street. Swapped with the A5006 when the M6 was built; the section along Wharf Street became the A500 in 1977. In the early 1980s, the route was cut back to Fleming Road and the remainder became a portion of the A52 one-way system.
B5042 (defunct)
A52 in Stoke-in-Trent
A5006 in Stoke-on-Trent
Renumbered as a spur of the A52 due to completion of the A500 and rerouting of traffic away from Stoke town center; the northern end is now gone, lost under the A500.
B5043 (defunct)
A519 in Newcastle-under-Lyme
A34/A527 in Newcastle-under-Lyme
Became a portion of a rerouted A519 in the 1990s (the old route of the A519 was declassified).
Mostly follows the original route of the end of Watling Street. Originally ran from Wellington to the A5 southwest of town; upgraded to the A5223 around 1980, then declassified before 1982.
Intersects the A513 and A51; originally ran southeast of Whitchurch between the A529 (now A41) and the A442 (now B5065). Shown unnumbered on the 1932 Ten Mile map and had become a portion of the A442 in the 1935 renumbering. Declassified in the 2000s after the A53 Hodnet bypass was built.
Originally ran along Edleston Road in Crewe between the A5019 and the A534. Upgraded to Class I status as the A5078 in the late 1920s; the northernmost section is now unclassified as it is within the Crewe town center relief road.
Originally ran along New Road from the A54 in Winsford to Winsford & Over station; declassified, likely in 1931 after the station closed to passengers.
The western section from Wilmslow to Woodford was upgraded to a portion of the A5102 in the early 1930s and the remainder was upgraded to the A5149 in the 1960s.
B5093
A5145 in Didsbury
A6 in Levenshulme
Originally began west of Chorlton-cum-Hardy; this became a portion of the A6010 in 1971 and the B5093 was extended south along a portion of former A34 (this section was part of the A526 before that). An earlier route ran from the B5092 in Woodford to the A6 in Stockport. This was upgraded to Class I status as the A5102 in the early 1930s.
Originally ran from the A5/A5025 in Menai Bridge to the B5111 in Amlwch. This was upgraded to Class I status as an extension of the A5025 in the early 1930s. The southern end into Menai Bridge is now part of the B5420 after the A5025 was rerouted to meet the A5 (now A55) Llanfair PG bypass.
B5109
A5025 in Llanynghenedl
unclassified road in Llangoed
Originally ran from Llangefni to Beaumaris, but was soon extended to Llangoed. In 1935 it was extended west to Llanynghenedl, replacing a portion of the B5112.
Originally began at Llangristiolus and ran north to Llangefni, but this section became the A5114 after World War II. Section in Amlwch was formerly the A5025 (and B5113 before that).
B5112
A5 east of Bryngwran
B5111 in Llanerchymedd
Route south of Trefor was formerly the B4423. Route west of Trefor is now part of the B5109.
Originally ran from the A5 in Valley to the B5111 on the western side of Amlwch. Upgraded to an extension of the A5025 by the end of the 1920s. The final section into Amlwch was renumbered to the B5111 in the 1940s.
B5114 (defunct)
Loop off A544 south of Llandudno
Originally began in Llanrhos and ran along Bryn Lupus Road and Deganwy Road to Deganwy and then along a rail line to Tywyn, connecting the A544 to itself. The northernmost section was declassified by 1932 and was instead routed to the A544 in the center of Deganwy. This new route was upgraded to Class I status as the A496 in 1935 and is now the A546. The original northern end to Llanrhos remains unclassified.
Number also appears in the DfT Card Index from around 2002 on a route along Record Street in Ruthin, but no maps showing the route as a B road have been found.
Passes through Manchester University. Originally A526 (and A34 after that).
Originally ran from the A525 in Rhuddian to the A548 near Gronant. The section from Gronant to Prestatyn became an extension of the A548 by 1932 and the remainder was renumbered as an extension of the A547 in the 1950s.
B5118
Rhyl Coast Road, Rhyl
Wellington Road, Rhyl
B5119
A5151 in Dyserth
A548 in Rhyl
B5120
A547 in Prestatyn
A548 in Prestatyn
Originally ran along High Street, but this was closed to traffic; the route now runs along Ffordd Pendyffryn, Bridge Road and Bastion Road.
Originally from the A494 King Street to the A549 Chester Street in Mold. Downgraded by the end of World War II; the southern section is now part of the A541, but the remainder is unclassified.
Old route of A587 which was rerouted along the former B5264.
Originally ran from the A494 north of Mold to the A548 in Flint. Due to its importance, it was upgraded to Class I status as the A5119 after World War II.
B5125
A5104 and A55 spur at Broughton
B5126 in Northop
Old routing of the A55.
Originally ran from the A5119 south of Northop to the High Street in Northop. Declassified after the A55 North Wales Expressway was built.
Chester eastern bypass; rerouted in 1935 around Chistleton and to end closer to Moston than Upton. This new route was upgraded to Class I status as the A41 a few years later.
Includes section of former A41 bypassed by New Ferry/Rock Ferry bypass. All three roads at T-junction in New Ferry are B5136. Gap between Bebington and Clatterbridge accounted for by B5137 and B5151.
A road with the same number appears on road signs at the junction of A462 and Bloxwich Road North in Willenhall, West Midlands. This is almost certainly a typo for the former B4157 which was declassified in the 1970s. The road signs were installed in 2012 replacing ones damaged in an accident.
In Wilmslow, the first half mile is the old A34 road prior to the construction of the Wilmslow bypass

B5182
A5046 Tithebarn Street, Liverpool
A5053 Leeds Street, Liverpool
Runs along Pall Mall; continued to the A59, but this junction is now gone after the Kingsway Tunnel approach road was built and was shortened to the A5038. The B5182 was cut back to its current route in the 1990s.
B5183 (defunct)
B5182 Pall Mall, Liverpool
A565 Great Howard Street, Liverpool
Declassified.
B5184 (defunct)
A5046 Great Crosshall Street, Liverpool

A5038 Vauxhall Road, Liverpool
Ran along Banastre Street; now part of the A5053, which wiped out the road.

B5191 (defunct)
A5036 Regent Road, Bootle

Much of route now unclassified; the section just east of the A565 and the spur along Irlam Street are now part of the A5057.
B5192
Loop off A506 in Kirkby
Originally began at the A59 south of Aintree to the A577 in Skelmersdale. The route was split in two by the M57 and expansion of Kirkby and a new relief road was built through Kirkby. Part of the eastern section became part of the A506 (much of which is now the M58). The remainder of the route was upgraded to Class I status as a western extension of the A506 while the final section into Skelmersdale is now the B5312. The current B5192 (itself a portion of the original B5192) in Kirkby dates from the 2000s, although with a new southern end as the original has been lost under the M57.
A585 near Wesham
A583 near Kirkham
Originally the A585 and A583 (later A585) before they were rerouted onto bypasses.
A5027 Upton bypass near Upton, Wirral
B5139 in West Kirby, Wirral
Designated around 2005. B5192 is the only number duplicated three times.
Originally began at the A57 and ended at the-then A574. The route along Priestley Street is now part of a rerouted A57, the section along Froghall Lane, Tanners Lane and Pinners Brow is now unclassified (although some maps show it as the B5210) and the section along Marsh House Lane is now part of the A574, leaving only the section along Orford Lane as part of the B5210.
M6 J21, Martinscroft
A574 in Fearnhead
Duplicate number. Appears on the DfT Roads List as the B5310, but this is a typo.
B5211
M60 J13, Worsley
A5181 in Stretford
Originally ran from the A49 in Longford to the-then A574 in Padgate. Now a portion of a rerouted A50.
Formerly the A579 until the Atherleigh Way bypass opened.
Originally ran from the B5213 in Stretford to the B5217 in Chorlton cum Hardy; the western end is now part of the B5213 and the remainder upgraded to the A5145.
B5216 (defunct)
A5063 Trafford Road, Trafford
Trafford Park
Extended and upgraded to the A5081.
The number also appears in the DfT Card Index from around 2002 as a route along Long Street in Wigston. There is no evidence (apart from a single unofficial online reference) that the number was used for this route; official documents in 1978 and 2013 state the route as a portion of the B5418. The same reference also states that Paddock Street was a portion of the B5216, but this was a cul-de-sac before 1978 and is also odd that the number would have changed between 1978 and 2013.
B5220 (defunct)
A526 (now B5117) in Rusholme
A57 in Gorton
Section west of the A6 (along Dickenson Road) upgraded to the A6010 and the remainder declassified.
B5221 (defunct)

B5220 in Salford
Originally ended at the A6 in Salford, but was extended to the B5220 in 1935. In the 1960s, the section north of Plymouth Grove became a portion of a rerouted A34 and the remainder was upgraded to the A5184.
B5222 (defunct)
Albert Square, Manchester
A6 Market Street, Manchester
Upgraded to an extension of the A6042 (although this was out-of-zone), but is now declassified due to restructuring following the 1996 IRA bombing.
A577 Wigan Road, Lancashire
A58 Market Street, Lancashire
Now a spur of the A577.
B5223 (defunct)
B5219 in Moss Side

B5226 (defunct)
Trafford Road, Salford
New Park Road, Salford
Declassified.
B5227 (defunct)
A57 in Weaste, Salford
A6 at Brindle Heath, Salford
Upgraded to Class I status as the A5186 sometime after the 1970s.
Built in the 1970s, but the number did not appear on maps until 2011.
Originally ran along Corporation Street in Preston; became a portion of a rerouted A59. After the A59 was rerouted, the section north of Ringway became a portion of the A5071 and the southern portion downgraded to the C329.
First used along the southernmost section of Devonshire Road in Blackpool. Became a portion of a rerouted A587 by 1932 (old A587 became an unnumbered Class II road, although the two routes may have swapped numbers in the 1920s). After the A587 returned to its original routing to form a portion of the Blackpool eastern bypass, this became a portion of the B5124.
Next used along Bispham Road in Blackpool from the A587 to the A586, along the old route of the A587 (which was rerouted over the original B5264). Returned to the A587 after it was routed back to its original route; the old route of the A587 (the original B5264) is now the B5124. The OS maps show the last bit along Benson Road and the final part along Bispham Road as part of the B5264, despite it not showing on any other maps nor signed on the ground.
Originally ran between the A586 and the A6 in Catterall. Became a portion of a rerouted A6 in the early 1930s after it was diverted to follow the new western bypass of Garstang.
Originally ran from the A590 in Greenodd to the A593 in Torver. Upgraded to Class I status as the A5084 in the mid-1920s; the southern section is now part of the A5092.
B5280
B5245, Southport
A565 at Hesketh Park, Southport
Originally ran from the B5279 (now A5084) in Lowick Green to the B5281 in Gawthwaite. Upgraded to Class I status as the A5092 after World War II as part of a plan to allow traffic to access Broughton-in-Furness and points west by A-road without having to detour via Dalton.
Originally ran from the A590 in Barrow-in-Furness to Roose. Upgraded to Class I status as a portion of the A5087 by 1932; the section along Rawlinson Street is now unclassified.
B5283 (defunct)
A595 in Hallthwaites
A595 in Whicham
Became a portion of a rerouted A595 after World War II (the old route of the A595 is now the A5093).
First used from the A592 at Glencoyne Park to the A594 (now A66) in Troutbeck. This was upgraded to Class I status as the A5091 in the mid-1920s.
Next used from the then-B5320 just outside Stainton to the then-A594 at Penruddock, paralleling the current route. Became a portion of the A66 in 1968 after the M6 Penrith bypass opened.
First used on a route between Keswick and Bothel. Upgraded early on (1927-1928) to an extension of the A591; the southern end (within the Keswick bypass) is now part of the A5271 and the rest remains the A591.
May also have been used along the now-A5103 Princess Parkway/Princess Road in Manchester, as the 1932 and 1933 OS Ten Mile road maps show the number running through southern Manchester to the A560 on the southwest side of Northenden (now in Wythenshawe). The route is shown as the B529 (a typo) on a 1934 map. The 1934 OS Ten Mile map shows the route as upgraded to the A5103 and the B5290 along its current route near Lancaster.
First used from the B5292 in Cockermouth to the A595 near Egremont. Due to its importance, it was upgraded early on to Class I status as the A5086 in the mid-1920s.
Next used from the B5992 in Low Lorton to Buttermere. Became an extension of the B5289 in 1935.
B5298 (defunct)
A597 in Workington
A596 in North Side
Crossed the River Derwent. Became a portion of the A597 in 1988 after the Workington bypass was built.
Part of the route (from Waverbridge to Station Hill in Wigton) still exists, but the road is defunct following construction of the A596 Wigton bypass in the early 1990s.
First used along Victoria Road in Runcorn; the route was declassified after the A533 split the route in two. The eastern end is now the B5155.
Also appeared in the DfT Roads List as a route along Woolston Grange Avenue between the A57 and A574 east of Warrington, but this is a typo for the B5210.
Originally used as a bypass of Sale, connecting the B5166 to itself. Became a portion of the A6144 around 1970.
B5312
A577 east of Skelmersdale
A570 east of Skelmersdale
Former routing of the A577. A branch was later built to link to the current A577.
First used in 1924 along Finkle Street and Corporation Road in Carlisle. Upgraded to a spur of the A595 in the 1940s, although a portion has been bypassed. Next used as an inner relief road into Lichfeld; one portion was upgraded to the A5127 and the remainder declassified.
B5313 (defunct)
Tamworth railway station
A51 and A5003 in Tamworth
Declassified.
B5316 (defunct)
B5406 in Telford
A5 in Telford
Declassified by 1986.
B5317 (defunct)
Chester Road, Manchester
Water Street, Manchester
Maps showed the route as a B-road, but with no number. Became a portion of the A57 in the late 1960s, probably when the A57(M) diverted it through the city center.
Reserved on 25 January 2007 for Sheil Road in Liverpool. The road has been the B5188 since classification and there is no obvious reason why the number needs to change.
Bypassed former route of A59 through central Ormskirk
B5320
A592 in Waterfoot
A6 at Eamont Bridge
Original 1924 route ran from the A592 in Waterfoot to the then-A594 (now B5288) in Penrith, but much of the route became part of the A592 (the section through Redhills was downgraded to a minor road as it was bypassed by the A66) in 1969 when the M6 Penrith bypass opened. The B5320 was reassigned to a former routing of the A592.
A57 in Irlam
B5471 in Cadishead
Former routing of the A57 through Irlam. Some signs state that the B5320 continues past the B5471 under a former rail line back to the A57 at the southern end of the bypass, but maps disagree on this.
Part incorporated into rerouted B591; remainder un-numbered classified
B5332 (defunct)
A525 and A547 in Rhuddlan
A55 in Pant y Wacco
Much of route now the A5151; section east of Penfforddllan is now the A5026.

A5027/A5028 in Wallasey
B5142 in Wallasey
One section now part of the A5027.
B5334
A51 in Nantwich
B5074 in Nantwich
Former A530.
Originally ran along Park Street and Kinsey Street in Congleton, now unclassified and split up by the A54 relief road.
B5335 (defunct)
A54 in Middlewich
B5309 near Middlewich
Became a portion of the A530 between 1946 and 1956.
B5336 (defunct)
A5018 in Wharton Green
A533 near Mere Heath
Declassified in the late 1990s; the northern end no longer connected to a classified road (the A533 was rerouted) and the southern end was cut off by the rerouted A533.
The section along Towerlands Street later became part of the A5047 one-way system and Low Hill became part of the A580. The remainder was declassified after the A5047 was dualled and the A580 was extended.
B5341
A51 and A534 in Burford
A530 in Nantwich
The western end was originally the A51 (later A534) and the section south of the rail line was the A464 (later A529, and A530 after that).
Originally ran along New Park Road in Salford; was the A5065 before it was downgraded between 1960 and 1975. Now unclassified; some of the route is gone, part of the park or due to redevelopment.
Formerly continued west to B591 near Copt Oak, Leicestershire; south-western part incorporated into rerouted B591; remainder now un-numbered classified
The route of the A34 prior to mid-1990s Wilmslow / Handforth bypass
Originally ran west of Swadlincote from the B586 to the A511 (now A444). Both B5358s are shown on a 1932 map; this could be a map error, or both routes actually coexisted for some time. Whatever the result, this B5358 is now the B5353.
B5359
A34 in Wilmslow

A6 in Kegworth
A453 near Isley Walton
Rerouted to the south in 1970-1971 due to runway extension at East Midlands Airport (the road originally crossed the present runway), after which it was upgraded to the A5129 (now A453) shortly afterwards.
Originally ran along Talbot Lane in Stretford. By 1946 it was the B6410 (an out-of-zone number as the route was west of the A6), but has since been upgraded to a portion of the A5014.
Formerly routed from east of Kirkby Muxloe to the A46 (now A5460). Extended to and then over the B5419 by the 1970s; the western end was cut back piece by piece to the B5366. The western end (declassified in the 1960s) is now a part of the B5380 after the A46 bypass was built.

Former A453. Originally continued to Measham, but this section was declassified around 2000. The DfT Road Index from around 2002 states that the route continues to Castle Donnington.
Former routing of the A527. Maps show the route as part of the A5271, but this is rarely signed on the ground. The original renumbering, according to some maps, was B5999, but it is unclear if this number was actually used or if it was more of a copyright trap or a placeholder.
