A465 !!! Currently a massive roadworks that has been going on for a few years. A lot of temporary roads/roundabouts as the contractors move about. It isn’t what it used to be ! I did it last September en route to Windermere and Scotland. It certainly isn’t fast as the roadworks and 50 zones slow you. It is ok but not scenic...there are some very impressive bridges being built though. The Abergavenny end is ok having been the early rebuild section. From Hirwaun south is normal.
If you want scenic then Abergavenny on the A40 is better with options to branch off.
