The A484 road is in Wales connecting Swansea with Cardigan via Carmarthen.

Route

The road begins to the north of Swansea at the junction with the A483 and heads westwards. It continues over the Loughor bridge into Bynea, Carmarthenshire and through the centre of Llanelli and traverses near the south coast of Carmarthen Bay until it reaches Pembrey. After Pembrey, the road bears northwards and continues in a northerly direction towards Carmarthen. At the A40/A48 junction at Pensarn, the A484 follows the A40 to the junction with the Capel Dewi Road (B4300) and crosses the River Towy on Carmarthen Bridge and continues through eastern Carmarthen to Bronwydd Arms. Here it takes a northwesterly direction to Cynwyl Elfed, then northwards again. After the village of Llangeler, it turns west and continues westwards until the junction with the A487 in Cardigan.

Historical Alignment

Swansea

Prior to the Construction of the "Llanelli Link Road", the road diverged from the A483 started in Cadle at a fork, where Carmarthen Road and Pontarddulais Road diverged. The A483 continued, (as it still does) along Pontaraddulais Road, whereas the remainder of Carmarthen Road carried the start of the A484. The section of road was declassified and is in effect a residential cul-de-sac, since the original start of the road is now only open to buses. From the junction with Ystrad Road, the A484 continued along what is now the B4620 to Loughor.

Llanelli

The building of the Llanelli Link Road has also impacted significantly on the alignment of the A484 in Llanelli.

Carmarthen

Prior to the construction of the A40 Carmarthen Eastern Bypass, the A484 road, at the junction of the A40/A48 in south-east Carmarthen, continued in a northernly direction along Rhiw Babell, before reaching Heol Llangynnwr. Following the construction of the bypass, Rhiw Babell was declassified, and a part of Heol Llangynnwr from Hen Heol Llangynnwr to the new bypass was reclassified the A484, thus a 0.5 miles (0.80 km) length of the A484 is shared with the A40.
