# B roads in Zone 5 of the Great Britain numbering scheme

B roads are numbered routes in Great Britain of lesser importance than A roads. See the article Great Britain road numbering scheme for the rationale behind the numbers allocated.

## Zone 5 (3 digits)

| Road | From | To | Notes |
| 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. |

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. |

| 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. 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. |

| 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. |

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. |

| B5206 | Orrell, Greater Manchester | A571 near Billinge | |
| B5207 | A571 at Billinge | A574 at Culcheth | |
| B5207 | A5036 at Netherton | A565 at Thornton | Duplicated number, former A5207 |
| B5208 | A5267 in Birkdale, Merseyside | A565, Southport, Merseyside | Originally ran from Blackbrook to Old Boston. Upgraded to the A599 by 1932. |
| 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. |
| 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.

| 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. |

| B5255 (defunct) | | | Number given to a former section of the A572 along Lord Street in Leigh. The road is actually a spur of the B5215. |
| 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. |

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. |

| B5290 | A588 at Conder Green | Glasson Dock | 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).

| B5999 (defunct) | A500 in Porthill | A50 in Tunstall | 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. |
