A roads in Zone 6 of the Great Britain numbering scheme
[1] Number also appears in the DfT Road lists from around 2002 as "Reserved for use for the Kirkumgate - Disforth proposals".Next used from Kegworth to West Bridgford, linking the M1 at J24 to Nottingham; a portion of the route was formally the B679.Although the road was still classified in the 1990s, it did not have the A6020 number (it was moved to its current route in the 1930s) and had likely become a spur of the A57.Ran as a loop off of the A1 along the former A1 via through Newark-on-Trent Renumbered to the A616, B6325 and B6326 because there was no need for a Class I road through Newark after the bypass opened in 1990.The original route went from A62 in Newton Heath via Lightbowne Road to A6104 in Moston; this became part of an extended B6393 by the 1970s.Dropped in favor of a route from the M1 to the A1 that ran east of Leeds, eventually becoming the M1 extension.
