A roads in Zone 5 of the Great Britain numbering scheme

Originally ran from the A5 at Marble Arch to the A1 at Tally Ho Corner in North Finchley.

The A511 number also appeared in the "Co-driver: The AA Motorists Companion" (1965) on a route linking the M6 to Wigan.

After the pre Worboys direction signs were introduced, it was decided to give the route a more unique number to aid navigation, and it became a portion of the A1 in 1954.

A 1932 map does show a proposed A road between Walton, Liverpool and Pendlebury, Salford; this opened in 1934 as the A580, although it is likely it took over at least some of the concept of the A563.

Originally ran between Boar's Head and Duxbury Hall; became the A5106, probably early on as the number was recycled in 1934.

Originally proposed in 1935 as a renumbering of the eastern end of the A572 between Swinton and Worsley, because it ran parallel to the New Liverpool - East Lancashire Road (the A580).

London Road, previously the former A5 between Emstrey and The Column, created when the original Shrewsbury bypass opened in 1933.

Previously allocated to a road from Braunstone to Abbey Park, bypassing Leicester to the east; this was the B583 before it was upgraded.
