|Route outline (key)|
In 1935, the route through Ystalyfera between the two junctions with the B4298 was renumbered A4068; and the remainder to Sennybridge, A4067. Around Ystalyfera and Ystradgynlais much of the route has now been bypassed and the B4599 now follows much of the ex-B4297 in this area.
