Road From To Notes
A4 City of London (Holborn Circus) Avonmouth Originally London to Bath
A40 City of London (near St. Paul's Cathedral) Fishguard The longest A road in Zone 4 at 256 miles long
A41 Central London (near Marble Arch) Birkenhead A large section of the former A41, from Bicester to Solihull, was downgraded when the northern extension of the M40 motorway was opened, as was a section in Birmingham due to other road improvements; most of it is now the non-contiguous B4100. A41 rerouted along new dual carriageway, Black Country New Road, between West Bromwich and Wednesbury. Old route through Hill Top renumbered A4196.
A42 Kegworth Appleby Magna A continuation of the M42, hence the use of A42 despite being entirely in Zone 5. Previously allocated to a road from Reading to Birmingham; this became part of the A329, the A423 (this section now the A4074 and A4158), and the A34 (section from Oxford to the M42 is now the A4144, A44, A3400).

The section from Cheltenham to Heath End (North of Stratford on Avon) was mostly reclassified as B4632 and much of what was previously the A435 from Cheltenham to Bidford was renamed the A46. A piece of A438 from M5 J9 to Toddington also became part of the A46, and the current section of the A46 round Stratford was new build.
A47 Birmingham Lowestoft The original section between Birmingham and Nuneaton has mostly been now de-classified to B-roads, while the section between Nuneaton and Leicester via Hinckley has been largely de-trunked since the M69 runs a similar route.
