About Transport in Wales
See also: Trunk roads in Wales
The trunk road network carries around one third of road traffic in Wales. Around 80 per cent of traffic on Welsh roads is cars, taxis, and minibuses, mainly on east-west routes in north and south Wales.
Wales has 83 miles (133 kilometres) of motorways, all of which are in the south. The major artery is the M4, which enters Wales via the Second Severn Crossing and terminates at Pont Abraham in Carmarthenshire. The M4 in South Wales has 27 junctions and is an important route between the main urban areas in the region. It links Llanelli, Swansea, Neath, Port Talbot, Bridgend, Cardiff and Newport directly to London and the rest of Southern England and indirectly to the Midlands via the A449, A40 and M50.
Following construction of the new bridge the original Severn Bridge, which crosses the river further upstream at Chepstow, was re-numbered the M48 motorway. Via either motorway is necessary to pay a toll to cross the bridge on the M4 or M48 westbound, but not eastbound. The A48(M) is a small spur from the M4 from West Newport to East Cardiff.
The second major road is the A470 dual carriageway that connects Cardiff with the South Wales Valleys towns. It suffers from severe congestion especially during peak hours due to significant in-commuting to the Cardiff area.
The A465 Heads of the Valleys road, currently being upgraded to dual carriageway, provides a link between the M4 near Neath across the Heads of the Valleys to Abergavenny, Monmouth and England’s West Midlands via the A40 and M50.
The main arteries for North Wales are A494, running from Queensferry (near the English border) to Dolgellau. The road begins from the M56 motorway, connecting North Wales with Chester and Manchester Airport, both in England. More importantly the A55, which runs from Holyhead (for ferry connections to Ireland), Conwy, Llandudno Junction and Rhyl to a junction with the M53 motorway near Chester.
One of the oldest roads the A5 runs from the port of Holyhead south east to Bangor then down through Snowdonia to Betws-y-Coed, Corwen, Llangollen and over the English border south of Chirk. This route has served as the main passage for London-Dublin traffic for many years although its usage has been superseded by the A55 coast road. It’s now more famed as a scenic route and notorious for many Bank Holiday traffic jams.
Two routes serve as the main North-South links. The A483 begins near Swansea and takes a north-easterly route to Ammanford, Llandeilo, Llandovery, Llanwrtyd Wells, Builth Wells, Llandrindod Wells, Newtown, Welshpool, Oswestry and Wrexham, finally ending at Chester.
The A470 begins in Cardiff Bay and passes through Cardiff following a north-north western route on to Pontypridd, Abercynon, Merthyr Tydfil, Brecon, Builth Wells, Rhayader, Llangurig, Llanidloes, Llandinam, Commins Coch, Mallwyd, Trawsfynydd, Blaenau Ffestiniog, Dolwyddelan, Betws-y-Coed and terminates at Llandudno. It is a dual carriageway between Cardiff and Merthyr (where it meets the Heads of the Valleys Road, the A465), and the section of this route into Cardiff is heavily used.
