Wow! have not been down there for over 20 years, do nor recognise anything? I used the junction of A470/A465 a lot (where you started from) but does not look the same place that I have driven over loads of times, things change? this is immense< I think it will be a "better" road after completion? looks like another year at least (maybe early 2025? until finished road) when I find time to go and looksee?
It is a huge change to the Single 3 lane heads of the valleys road I've been driving since the 1970's.....and , until the vegetation grows a spectacular road for scenic views.
Sorry I wrong, You started from junction of A465 and A 4060, not A 465 And A470 (typed out just after start? not studied the road sign? until you got to the A470, I am daft.
Its all very confusing down there for sure, and my numerous videos of it!!!... I started this video coming out of Asda at Dowlais Top .....then right onto the A465
