The A483 begins at junction 42 of the M4 motorway, just east of Swansea. From here, it travels west along the Fabian Way towards Swansea city centre, where it turns to a northwesterly direction. It meets the M4 again at junction 47 at Penllergaer, after which it multiplexes with the A48 along Swansea Road, Bryntirion Road and Bolgoed Road to Pontarddulais.
After Pontarddulais, the route continues along Heol Fforest and Carmarthen Road. It diverges from the A48 at the terminus of the M4, junction 49, turning northeast towards Ammanford and then north towards Llandeilo. At Llandeilo it meets the A40, then multiplexes with this route as far as Llandovery. From here, it continues north into Powys.
The A483 continues through Llanwrtyd Wells, Builth Wells (where it intersects with the A470) and Llandrindod Wells. It intersects with the A44 at Crossgates, just north of Llandrindod Wells, then continues to Newtown, where it passes under the Cambrian Line at the Dolfor Road Railway Bridge. This low bridge, with a height restriction of 13 ft 3 in (4.04 m), has been hit by high vehicles on many occasions. From Newtown the road continues to Welshpool, running roughly parallel to the River Severn, before crossing the border into England at Llanymynech.

Just south of Chester, the A483 intersects with the A55 North Wales Expressway. It then continues as a single carriageway to its terminus at the city centre, crossing the Grosvenor Bridge over the Dee.
There have been calls to upgrade the road from Shrewsbury to Wrexham, including the section of the A483 from Oswestry to Ruabon, to dual carriageway. There has also been a campaign by residents of Llanymynech and nearby Pant for an A483 bypass around these villages.
