The route from
Aberaeron, where it branches off the A487, joins the
A40 at Llanwrda, is generally orientated from northwest to southeast. Running through the pleasant countryside of the Aeron Valley, it passes the Grade I listed manor house of
Llanerchaeron near
Ciliau Aeron. The B4339 branches off to the right and the A482 continues to the village of
Ystrad Aeron where the B4342 branches off to the right. After continuing through the village of Temple Bar, it enters Lampeter to join the
A485 road. Within a few hundred yards the
A475 road branches off to the right and just south of the town the A482 crosses the
River Teifi and enters Carmarthenshire and the
A485 Carmarthen road branches off to the right. Still travelling southeastwards, the A482 climbs to higher elevations and passes through grasslands and wooded areas. It crosses the
River Cothi at
Pumsaint and continues winding through rural scenery to Llanwrda. == See also ==
