Arguably the most famous road in Wales, the A470 is 186 miles from shore to shore through the backbone of Wales, linking north to south.

Peaceful and picturesque or slow and never-ending: the road out of here, the road home, the beginnings of devolution? Glorious national parks, bypasses, being stuck behind a certain lorry firm or worse, a caravan, the road to the Royal Welsh? From the seashore to slates, from nuclear power stations and fighter plane flypasts to forests and mountains: Bwlch yr Oerddrws, Pen Y Fan. On the road or on a journey, there's no need to take the A470 too literally.

Be ydi'r A470 i chi - siwrne dawel trwy harddwch Cymru neu daith araf a diddiwedd? Ai hon yw'r ffordd i adael, neu'r ffordd adref, neu ddechrau datganoli? Parciau Cenedlaethol, ffyrdd osgoi, llusgo mynd tu ol i lori neu waeth fyth garafan, y ffordd i'r Sioe Frenhinol? Traethau, chwareli, pwerdai niwclear, awyrennau rhyfel, coedwigoedd, mynyddoedd, Bwlch yr Oerddrws, Pen y Fan? Taith ddiriaethol ar y tarmac neu daith o fath gwahanol? Does dim rhaid dehongli'r A470 yn llythrennol.
