The '''A470''' (also named the '''Cardiff to Glan Conwy Trunk Road''')<ref name="Trunk Road">{{cite web|url=http://gov.wales/topics/transport/roads/land-acquisition-compensation/p1compclaims/publicnotices/cardiffglanconwy/?lang=en|title=The Cardiff to Glan Conwy Trunk Road (A470) (Gelligemlyn Improvement, Side Roads) Order 201-|publisher=[[Welsh Government]]|access-date=2014-06-05}}</ref> is a [[trunk road]] in [[Wales]]. It is the country's longest road at {{convert|186|mi}} and links the capital [[Cardiff]] on the south coast to [[Llandudno]] on the north coast.<ref name="BBCW">{{cite news|url=https://www.bbc.co.uk/news/uk-wales-49180014|title=A470: Images of Wales's longest road from south to north|publisher=BBC News|date=4 August 2019|access-date=2021-06-11}}</ref> While previously one had to navigate the narrow roads of [[Llanidloes]] and [[Dolgellau]], both these market towns are now bypassed due to extensive road modernisation{{when|date=July 2022}}. The {{convert|26|mi}} from Cardiff Bay to [[Merthyr Tydfil]] are mainly [[dual carriageway]], but most of the route from north of Merthyr to Llandudno is [[single carriageway]].

==Route==
===National parks===
The road travels through two of the [[national parks of Wales]]: the [[Brecon Beacons National Park|Brecon Beacons]], and [[Snowdonia National Park]] starting just south of [[Dinas Mawddwy]].

===Cardiff Bay – Merthyr Tydfil===
{{more citations needed|section|date=July 2022}}
[[File:North Road, Cardiff.jpg|thumb|left|North Road (Cardiff) tidal flow system, a 3-lane single carriageway]]
The southernmost point of the route is in [[Cardiff Bay]], outside the [[Wales Millennium Centre]].  It runs up [[Lloyd George Avenue]] (this was previously Collingdon Road, and the A470 previously ran along the parallel [[Bute Street (Cardiff)|Bute Street]]), and continues along St. Mary Street in central [[Cardiff city centre|Cardiff]].  The road then becomes North Road, and after a [[Reversible lane|tidal flow]] system running to [[Maindy]] and then goes over the flyover at the [[Gabalfa]] interchange of the [[A48 road|A48]] and the [[A469 road|A469]].  It becomes an urban dual-carriageway along Manor Way, with a {{convert|30|mi/h|km/h|abbr=on}} speed limit and with many traffic-signalled crossings. It passes without interruption under the [[M4 motorway|M4]] at the giant [[Coryton, Cardiff|Coryton]] roundabout. For the next {{convert|15|mi|km}} it is a modern high-speed dual carriageway by-passing [[Tongwynlais]] and [[Castell Coch]], [[Taff's Well]], to [[Pontypridd]]. Heading north to [[Abercynon]], the road now follows the route of the [[Taff Vale Railway]]s [[Llancaiach Branch]] to Quakers Yard roundabout,<ref name="EEvans">{{cite web|url=https://steamindex.com/backtrak/bt10.htm|title=The Nelson branch |first=Edward A. |last=Evans |pages=12–17 |publisher=Backtrack |year=1996 |volume=10 |access-date=2009-03-14}}</ref> where it is joined by the A4059 from [[Abercynon]], [[Aberdare]] and [[Hirwaun]]; the [[A472 road|A472]] from [[Ystrad Mynach]] and [[Pontypool]] finally the A4054 from [[Quakers Yard]], and [[Merthyr Tydfil]].

From Quakers Yard roundabout (locally known as "Fiddlers Elbow"), {{convert|5.5|mi}} of dual carriageway takes the road to the Pentrebach roundabout where the A4060 links, and then to the Merthyr Tydfil roundabout where the road meets the [[A465 road|A465]] and the dual carriageway ends. A twisting section alongside the [[Taf Fawr]] reservoirs of [[Llwyn-on Reservoir|Llwyn-on]], [[Cantref Reservoir|Cantref]] and [[Beacons Reservoir|Beacons]] takes the road to its highest point at [[Pen y Fan#Storey Arms|Storey Arms]] on the pass over the [[Brecon Beacons]] before a long descent to [[Brecon]].

===Merthyr Tydfil – Builth Wells===
[[File:A470 at Bwlch Oerddrws.jpg|thumb|left|The A470 at {{ill|Bwlch Oerddrws|cy}}, between Dinas Mawddwy and Dolgellau]]
The remainder of the route north of Brecon consists of older routes now renamed "A470". This artificiality is apparent as a driver following the entire route north to south must diverge from the main line of respective stretches of road no fewer than five times. A short three lane stretch heads north east before a sharp left turn is required to stay on the road. From this point on the road becomes narrow and twisting and overtaking is problematic except at a few straight sections. Another sharp left turn at a stop sign in [[Llyswen]] takes the road alongside the [[River Wye]] into [[Builth Wells]].

===Builth Wells – Mallwyd===
[[File:A470 at Bwlch Oerddrws from Maesglase.jpg|thumb|left|The A470 snaking across Bwlch Oerddrws seen from [[Maesglase]]]]
The road continues to follow the Wye to the busy crossroads where it meets the A44 in the centre of [[Rhayader]]. On reaching [[Llangurig]], a right turn outside the village takes the road past [[Llanidloes]] and through [[Llandinam]], the birthplace of [[David Davies (industrialist)|David Davies]] and now the headquarters of [[Girlguiding UK|Girl Guides Wales]]. Another anomalous left turn at a [[level crossing]] sets the path for [[Caersws]], [[Carno]] and [[Llanbrynmair]]. Just beyond the village of [[Talerddig]] the road descends and crosses under the [[Cambrian Line|Shrewsbury–Aberystwyth railway line]]. The long descent towards [[Commins Coch]] is a relatively new stretch of road that replaced a set of road-works that had traffic light controlled single lane working for over 10 years because of unstable ground conditions. The river bridge at [[Commins Coch]] is so narrow and set at such an angle that only one vehicle at a time can pass. At [[Cemmaes Road]] the road joins the [[A487 road|A487]] at a roundabout.  A right turn at the roundabout takes the road on to [[Mallwyd]] where the [[A458 road|A458]] joins at yet another roundabout.

===Mallwyd – Llandudno===
The country becomes more forested and the road climbs up through [[Dinas Mawddwy]] and then steeply up the eastern foot-hills of [[Cadair Idris]] before dropping down to the [[Dolgellau]] by-pass. More sharp twists and turns in the forestry and through the village of [[Ganllwyd]] brings the road up onto the high plateau of the Cambrian dome where the road follows the ancient track of [[Sarn Helen]] Roman road passing the redundant nuclear power station at [[Trawsfynydd]]. A right turn beyond the power station takes the road on to [[Ffestiniog]] and [[Blaenau Ffestiniog]] before heading over the [[Crimea Pass]] to [[Dolwyddelan]]. A sharp left turn interrupts the A470 as it becomes the [[A5 road (Great Britain)|A5]] for a short distance towards [[Betws-y-Coed]] before turning right again back onto the A470 just before [[Waterloo Bridge, Betws-y-Coed|Waterloo Bridge]]. Passing down the valley of the [[River Conwy]] the road passes through [[Llanrwst]], [[Tal-y-Cafn]] and [[Glan Conwy]], at which point there is a dual roundabout that intersects with the [[A55 road|A55]] North Wales Expressway before descending into [[Llandudno]]. The northernmost point of the route is in [[Llandudno]] itself at the sea front, where it meets the North Shore Parade, the [[A547 road|A547]].

== History ==
[[File:Taff's Well Interchange during construction 2-11-1971.jpg|thumb|right|Taff's Well Interchange during construction in November 1971]]

===Modern route===
The modern route of the A470 arose from a campaign in the 1970s by the ''[[Western Mail (Wales)|Western Mail]]'' for a single route connecting North and South Wales, in the lead up to the [[1979 Welsh devolution referendum]]. It was successful, and in 1978, the Welsh Office discussed a potential course of the road roughly through the centre of the country, which was implemented the following year.<ref>{{cite web|url=https://www.iwa.wales/agenda/2010/03/a-road-to-love-for/|title=A Road to Love For|work=IWA|first=John|last=Osmond|date=26 March 2010|access-date=17 August 2020}}</ref>

===Original route===
The route from [[Cardiff]] to [[Brecon]] was the original A470.<ref>{{cite web|url=http://www.sabre-roads.org.uk/maps/index.php?view=A470&gr=51.63083,-3.28315&map=NPEMap&zoom=6&layer=4|title=MOT Map|publisher=[[Ordnance Survey]]|year=1923|access-date=16 April 2012}}</ref> It originally ran into Brecon town centre and joined the [[A40 road]]. The old A470 between the by-pass and the town, along Newgate Street, is now the B4601. A4062 was the number for the section from the junction of the A40 and the B4601 – the Brecon (eastern) bypass to B4602 section. The B4601 was originally the A40 which ran through the town of Brecon. Similarly, the B4602 was originally the westernmost part of the A438.

[[File:A470 @ Rhayader.jpg|thumb|right|The A470 passing through Rhayader]]

===Original road numbers===
====Brecon – Llangurig====
The A438 was the original number for the road from the junction with B4602 to the sharp left turn where A470 turns north in the vicinity of [[Llanfilo]]. The A438 continues on from there to [[Hereford]] and [[Tewkesbury]]. From north of Llanfilo to [[Llyswen]] was the A4073. A479 originally linked the A40 west of [[Crickhowell]] to the [[A44 road]] at [[Rhayader]]. The A479 now runs only from Crickhowell to Llyswen. The stretch from Rhayader to [[Llangurig]] was the A44.  Officially, this is now part of the A470,<ref>{{cite web|url=http://www.sabre-roads.org.uk/maps/index.php?view=A470&gr=52.35346,-3.56760&map=OSMap&zoom=6&layer=0|title=1:250,000 Road Map|publisher=[[Ordnance Survey]]|access-date=16 April 2012}}</ref> but some local signage shows A44/A470.{{citation needed|date=April 2012}}

====Llangurig – Mallwyd====
From Llangurig to Moat Lane (east of [[Caersws]]), it was once part of the A492, which originally ran from Llangurig to [[Newtown, Powys|Newtown]].<ref>{{cite web|url=http://www.sabre-roads.org.uk/maps/index.php?view=A470&gr=52.45321,-3.52262&map=NPEMap&zoom=7&layer=1|publisher=[[Ordnance Survey]]|title=One Inch Seventh Series|access-date=26 May 2012}}</ref> The section Moat Lane to Newtown has since been renumbered A489, and from Moat Lane to [[Glantwymyn]] the A470 replaced the A489 which ran all the way from [[Machynlleth]] to the [[A49 road]] north of [[Craven Arms]] in south [[Shropshire]]. Now the A489 designation applies to two roads separated by {{convert|17|mi}} of the A470. The stretch between Glantwymyn to Mallwyd was called the A4084.

====Dolgellau====
Originally starting at the Cross Foxes near [[Dolgellau]] the A458 now runs only from Mallwyd to [[Shrewsbury]]. It now starts at Mallwyd with the Mallwyd to Cross Foxes section being the A470. Cross Foxes to near Gellilydan (in the [[Meirionydd]] part of [[Gwynedd]] south of [[Ffestiniog]]) brings us to a complicated series of route renumbering.  This stretch was originally the A487 which ran through Dolgellau town centre. The modern A470 bypasses the town using the line of the old [[Ruabon Barmouth Line|Ruabon – Morfa Mawddach railway]].

====Gellilydan – Llandudno====
Gellilydan via Llan Ffestiniog to [[Blaenau Ffestiniog]] (Congl-y-Wal) was not originally allocated a number. The section from Blaenau Ffestiniog to [[Betws-y-Coed]] was the B4407, and from there to [[Llandudno]] was the A544.<ref>{{cite web|url=http://www.sabre-roads.org.uk/maps/index.php?view=A470&gr=53.00923,-3.85994&map=NPEMap&zoom=7&layer=4|title=MOT Map Sheet 11|publisher=[[Ordnance Survey]]|year=1923|access-date=16 April 2012}}</ref> By 1946, the A496 had become extended to Llandudno.<ref>{{cite web|url=http://www.sabre-roads.org.uk/maps/index.php?view=A470&gr=52.98180,-3.90568&map=NPEMap&zoom=6&layer=6|title=Ten Mile Map of Great Britain|publisher=[[Ordnance Survey]]|year=1946|access-date=16 April 2012}}</ref>

The section of road from Glan Conwy corner to Llandudno is a new well aligned direct route to Llandudno. The old A496 has been renumbered A547 between Glan Conwy and Llandudno Junction and A546 between Llandudno Junction and Llandudno. The A496 now numbers only the Dolgellau – Blaenau Ffestiniog coast road.
