Some maps and all signs state the route as part of the B1426, however other maps, as well as Gateshead MBC, still state the route as B601. |

| B663 | Bythorn | Caldecott | |
| B664 | A427 near Market Harborough | Uppingham | First used at Irthlingborough, cutting the corner between the A6 and B663. It was upgraded to Class I status early on and had become part of the A605 by the 1950s (probably had this number by the end of the 1920s). But following the construction of the current A45, the road was torn up and is now completely gone, nothing more than a faint line in a field.
The second use was from the A43 north of Stanion to the A427 in Corby. Upgraded to Class I status as the A6116 in 1935; the section east of Corby is now part of the A6086 and the remainder unclassified. |

| B679 | A60 in West Bridgford | A453 at Silverdale, Nottinghamshire | Formerly part of the A648 |
| B680 | A60 at Ruddington, Nottinghamshire | B679 at Wilford, Nottinghamshire | |
| B681 (defunct) | A52 in Nottingham | A60 in Nottingham | Nottingham western bypass; the southern section became part of the A453 (now A6005) around 1935 while the remainder held on through the 1960s before it too was upgraded to Class I status, and is now the A6130. |

| B688 (defunct) | A46 east of East Bridgford | A614 in Warren Hill | The southern section between the A46 and A612 was upgraded to Class I status early on, becoming the A6097, although much of this section returned to the B688 after the East Bridgford bypass and a new Gunthorpe Bridge (opened 1927) were built (the new road got the A6097 number). With the old bridge gone, this left the B688 with a gap over the River Trent, requiring a detour via local roads and the A6097. Later maps showed that the A6097 had replaced the B688 piece by piece. A section in Oxton was numbered as part of the B6386, but this is now unclassified. |
| B689 (defunct) | A1 (now B6326) in Newark-on-Trent | A46 in Newark-on-Trent | Was the highest-numbered and northernmost 3-digit road B road in England. Upgraded to Class I status, either as a spur of the A46 or an out-of-zone extension of the A17. Now part of the B6166 after Newark was bypassed by the A1 and A46. |

The entire original section, including the Odsal Top spur, became an extension of the A6036 in the 1960s, leaving the 1940s extension as the B6148. Around then the eastern section (between the A647 and B6145) was rerouted along Horton Grange Road and Ingleby Road.
