The numbering zones for roads in Great Britain

Zone 5 (3 digits)

B500	A40 at Holborn Circus	A1 at Barbican tube station	Charterhouse Street and Long Lane around Smithfield Market
B501	A401 at Islington	B500 Charterhouse Street, Smithfield Market	St John Street, except for the section north of Rosebery Avenue which is part of the A401
B502	A4200 at Russell Square	B144 Bath Street in Finsbury	This road is split into two parts by the A201 and A401 at Mount Pleasant
B503 (defunct)	A401 at Mount Pleasant	A501 at Kings Cross	Now part of the A201.
B504	A5202 at St Pancras	B502 at Bloomsbury	Northern section passes St Pancras International on the west side and is southbound-only for through traffic.
B505 (defunct)	A40 at Oxford Circus	A400 at Camden	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.

B508 (defunct)	A5 in Maida Vale	B505 (now A4201) near Camden	Upgraded to the A5205, likely early on because the number fits into the original system (four-digit A roads in central London were numbered Ax2xx).

B510	A41 at Child's Hill (Fortune Green)	A5 at Kilburn	Along Fortune Green Road and West End Lane through West Hampstead. Terminates at Quex Road while Abbey Road is the B507

B515	A1 at Holloway	A1 at Islington	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.

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.

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.

B5147	Birkenhead Central railway station, Merseyside	B5148 in Tranmere	A road with the same number appears on road signs at the junction of A462 and Bloxwich Road North in Willenhall, West Midlands.

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.

B5209	A572 at Haydock	A599 at Newton-le-Willows
B5210	Lythgoes Lane, Warrington	Longford Street, Warrington	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.
B5215	A572 at Leigh, Greater Manchester	A577 at Atherton, Greater Manchester	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.

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.

B5256	A675 at Hoghton, Lancashire	Leyland, Lancashire
B5257	B5254 at Lostock Hall, Lancashire	B6258 at Bamber Bridge, Lancashire
B5258	A587 Fleetwood Road, Anchorsholme	Bispham Road, Norcross	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.

B5261	Blackpool, Lancashire	Lytham, Lancashire
B5262	Blackpool, Lancashire	Squires Gate, Blackpool, Lancashire
B5264	Plumpton Lane, Woodplumpton	Woodplumpton	Formerly the C346 before 2009. 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.

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.
B5281	A590, Ulverston (Tank Square roundabout / Brewery Street)	A5092, Gawthwaite	The route is split in Ulverston with two separate roads designated 'B5281'. This is due to Ulverston's one-way system.

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.
