A5267 road

List of A roads in zone 5 in Great Britain starting north/east of the A5, west of the A6, south of the Solway Firth/Eden Estuary (roads beginning with 5).

although some old maps have the A5000 ending at the west on the A502, with that number taking over the remainder.

The Road acts as a northern bypass to the London Inner ring-road between the Edgware Road and Great Portland Street section, and as such is a much faster route than the A501 in this section at all times.
