Originally used from Althorne to Southminster. Renumbered as an extension of the B1018 around 1992 (the B1020 number appears on the 1991 edition of the OS 1:250k map but not the 1993 edition).

Next used from Old Harlow to Pinnacles as part of Harlow New Town. The section east of the Burnt Mill Roundabout became A1019 for a time in the 1970s, but is now the A414. The remainder is now part of the A1169.

A section of the old route within Norwich remains numbered as the B1140.

Originally used along Broadgate Lane in Deeping St James. Renumbered as a portion of the B1162, probably in 1935.

Originally used from Newland to Newport. Due to its importance, it was upgraded to Class I status as a portion of the A1102 Lincoln bypass, but was downgraded back to Class II as the B1273 following the construction of the A46 bypass. The number was also assigned to St Mary's Street between the-then A15 and B1188 (now A15). This road was not classified until the mid-1920s, so it is unknown if the two routes existed concurrently or was allocated afterwards. This B1193 was renumbered to A1190 when the A15 was rerouted, later becoming the eastern section of the A57 and is currently the B199.

Originally used along Quayside in Newcastle upon Tyne. Now unclassified.

Originally used along Market Street in Newcastle upon Tyne. In 1929, the B1306 was put out-of-zone due to rerouting of the A1, so it was renumbered to B6440. The route is now pedestrianized.

Next used on a route from Hebburn to Hebburn Colliery. It is not known when the route received its number due to its short length, but it was in existence by the late 1940s. Became a portion of the B1297 in the 1970s when it was routed away from Jarrow, but was declassified when the B1297 was rerouted back to Jarrow.

Originally ran from the A191 in Benton Square to the A1060 (later A188) in West Moor. After World War II the route was extended along a section of the B1319 and all of the B1320 to the A1 at Wide Open. In the 1960s, the western section was split by an upgraded A189, the section along the former B1320 was upgraded to the A1056 and the original section of the B1318 became part of the B1505.

A193 Broadway/Rotary Way

Originally ran from the A194 (now A193) in Bebside to the A196 in Stakeford. The southern section was declassified in 1961 due to completion of the Kitty Brewster Bridge over the River Blyth east of the Furnace Bridge, and the B1330 was moved onto this route to Bedington Station. In 1970 or 1971 the route was extended north to Stakeford Road. The route over the bridge was renumbered to A189 in 1975; the remainder was upgraded to Class I status as the A1147.
