A roads in Zone 4 of the Great Britain numbering scheme

List of A roads in zone 4 in Great Britain starting north of the A4 and south/west of the A5 (roads beginning with 4).

Single- and double-digit roads


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.
A42	Kegworth	Appleby Magna	A continuation of the M42, hence the use of A42 despite being entirely in Zone 5. Early road atlases show the A42 running along the present A4074 and A34 from Reading to Birmingham.
A43	M40 motorway Junction 10 north of Bicester	Stamford
A44	Oxford	Aberystwyth	Officially the most dangerous road in Wales between Aberystwyth and Llangurig.^[1] Between Evesham and J6, M5, originally A4538.
A45	Birmingham	Thrapston	Previously continued along route of current A14 to Felixstowe
A46	Bath	Cleethorpes	Most of the section betweens Evesham and Leicester replaced by new-build sections, as well as the M69 motorway between Coventry and Leicester. 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	Leicester	Lowestoft	The section between Birmingham and Nuneaton has 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. A12 from Great Yarmouth to Lowestoft redesignated as A47 in 2017.
A48	Highnam near Gloucester	Carmarthen	Originally began in Worcester. Worcester to Newport is now A449.
A49	Ross-on-Wye	Bamber Bridge
