The '''A48''' is a road in [[Great Britain]] running from the [[A40 road|A40]] at [[Highnam]], {{convert|3|mi}} west of [[Gloucester]], [[England]], to the A40 at [[Carmarthen]], [[Wales]]. Before the [[Severn Bridge]] opened on 8 September 1966, it was a major route between England and [[South Wales]]. For most of its route, it runs almost parallel to the [[M4 motorway]]. During times of high winds at the Severn Bridge, the A48 is used as part of the diversion route and is still marked as a Holiday Route.

From Gloucester, the A48 runs through the villages of [[Minsterworth]], [[Westbury-on-Severn]], connects to a link road to [[Cinderford]] in the [[Forest of Dean]] then through [[Newnham on Severn|Newnham]], [[Blakeney, Gloucestershire|Blakeney]] and since 1995, [[Bypass (road)|bypassing]] [[Lydney]] on the west bank of the [[River Severn]]. It crosses the [[England–Wales border]] at [[Chepstow]] and continues westwards close to the South Wales coast passing [[Newport, Wales|Newport]], [[Cardiff]], [[Cowbridge]], [[Bridgend]], [[Pyle]], [[Port Talbot]], [[Neath]] and [[Swansea]], before terminating at the junction with the A40 near the centre of [[Carmarthen]].

Parts of the road, along with other roads, form the London–Fishguard and Swansea–Manchester [[trunk road|trunk roads]], when they were designated in 1937.<ref name="Act 193622">{{cite web |title=Trunk Roads Act 1936 |url=http://www.legislation.gov.uk/ukpga/1936/5/pdfs/ukpga_19360005_en.pdf |accessdate=2025-09-09 |publisher=[[Legislation.gov.uk]]}}</ref>''<ref name="Watson2">{{cite web |title=Trunk Roads Act 1936 and 1946 |url=http://www.watsonlv.net/pdf/trunk_roads.pdf |accessdate=2025-09-09 |publisher=Leslie V Watson}}</ref>''

==Route==
===Highnam to Cardiff===
The A48 from Highnam to Newport runs adjacent to the [[River Severn]]. After running through a series of villages, it crosses the [[England–Wales border]] at [[Chepstow]]. The section between Higham and Chepstow is still a primary route of some importance for the Forest of Dean. 
From the [[M4 Motorway]] at J15 near Swindon, traffic is directed for Wales if it is over the [[Severn Bridge]] weight limit of 44 tonnes. Traffic is directed onto the A419, then onto the [[A417 road|A417]] after Cirencester, and at Gloucester, onto the A40. This road has some speed cameras, as there have previously been incidents here, and have been erected to prevent them from happening again. During busy periods, such as the Severn Bore, this road may become busy with parked cars near the river's edge. Apart from morning and evening rush hours, the road is generally quite empty and free running, with no heavy traffic reports. The road also runs next to the [[Forest of Dean]]. The woods may be viewed from the roadside, as may the hills of the Dean. There is a [[level crossing]] in Lydney. Until Chepstow, there is a height limit under the low [[railway bridges]]. Tall vehicles are directed to Newport on the A40. For some parts of this route, short distance dual carriageways occur, especially on steep hills. 
At Chepstow, the road links [[Gloucestershire]] with [[Monmouthshire]]. The road runs through Chepstow. There is access to the Forest of Dean in Chepstow. At the end of the road in Chepstow (at the roundabout), the Primary Route ends here, and it meets the A466, a road that provides access to the [[Wye Valley]] and to the [[M48 motorway]], originally the M4. Access to the M4 is available on this road. The A48 becomes a secondary route here, and continues bypassing [[Caldicot, Monmouthshire|Caldicot]], [[Caerwent]] and [[Langstone, Newport|Langstone]].

The A48 then continues to M4 junction 24, from which point it is also known as the [[Southern Distributor Road]], which is entirely a [[dual carriageway]] with two lanes in each direction around the southern end of Newport until M4 junction 28. From junction 28 it remains a dual carriageway until just after the Celtic Way roundabout where it becomes a single carriageway with four lanes past [[Castleton, Newport|Castleton]], and then merges with the junction 29A of the [[A48(M) motorway]] at [[St Mellons]], where it again becomes a dual carriageway with two lanes in each direction, where it is known as the Eastern Avenue until the Gabalfa Interchange, where it is known as the Western Avenue and is largely a single carriageway with four lanes until Culverhouse Cross interchange.

===Cardiff to Carmarthen===
From the Culverhouse Cross interchange on the western border of Cardiff the road is mostly a single carriageway with two lanes until Cowbridge, where it becomes the Cowbridge [[Bypass (road)|Bypass]] which is a [[dual carriageway]], until again it becomes a single carriageway with two lanes until Bridgend when it is a dual carriageway again. From Bridgend it becomes a single carriageway, until Port Talbot where it is a dual carriageway, and originally known as the [[A48(M) motorway|A48(M) (Port Talbot Bypass)]] until the M4 was extended. The A48 then ends on the western end of the Briton Ferry Bridge at junction 42 of the M4 and starts again at junction 44 where again it is a single carriageway until the end of the M4 at junction 49 where it becomes a dual carriageway and forms part of the main [[trunk road]] between [[Pont Abraham Services]] to [[Carmarthen]] where the A48 ends.

==History of the road number==

The original (1923) route of the A48 was [[Worcester, England|Worcester]] to Carmarthen via [[Malvern, Worcestershire|Malvern]], [[Ledbury]], [[Ross-on-Wye]], [[Monmouth]], Newport, Cardiff, Bridgend, Neath and [[Llanelli]]. In 1935 it was rerouted east of Newport, replacing the A437 between Newport and Gloucester.  The road from Worcester to Newport became part of the [[A449 road|A449]], apart from the section between Ross and Monmouth (which became part of the A40).

==Road safety==
In June 2008, the {{convert|27|mi|adj=on}} Gloucester{{spaced ndash}}Chepstow stretch of the A48 was named as the most dangerous road in South West England. This single carriageway had 45 fatal and serious injury [[car accident|collisions]] between 2004 and 2006, and was rated as medium risk in the [[EuroRAP]] report published by the [[Road Safety Foundation]].<ref>{{cite web|title=Getting ahead|url=http://www.roadsafetyfoundation.org/media/14940/getting%20ahead.pdf|publisher=Road Safety Foundation|access-date=21 September 2013|author=Dr Joanne Hill|page=13|date=July 2008|archive-url=https://web.archive.org/web/20130922212650/http://www.roadsafetyfoundation.org/media/14940/getting%20ahead.pdf|archive-date=22 September 2013|url-status=dead}}</ref>

On 6 March 2023, five people were found after they had been missing for two days. Three of the five were found dead following a believed car crash after their car was found on the A48 in [[St Mellons]], with the other two injured.<ref>{{Cite news |last=Thomas |first=Alun |last2=Griffith |first2=Hywel |last3=Bourne |first3=Nick |date=6 March 2023 |title=Cardiff car crash: Three of missing five found dead |work=[[BBC News]] |url=https://www.bbc.co.uk/news/uk-64859195 |access-date=6 March 2023}}</ref>
