A465 road

The A465 is a trunk road that runs from Bromyard in Herefordshire, England to Llandarcy near Swansea in south Wales. The western half in Wales is known officially as the Neath to Abergavenny Trunk Road, but the section from Abergavenny to the Vale of Neath is more commonly referred to as the Heads of the Valleys Road because it links the northern heads of the South Wales Valleys. This section was also the subject of a major upgrade programme to convert the road into a dual carriageway with two lanes in each direction, and the final completed section opened on 31 May 2025, bringing a 23-year long scheme to a close. Approximately following the southern boundary of the Brecon Beacons National Park, the Ordnance Survey Pathfinder guide describes it as the unofficial border between rural and industrial South Wales. The A465 provides an alternative route between England and the counties in South West Wales and to the ferries to Ireland.
