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. From the seashore to slate quarries, from nuclear power stations and fighter plane flypasts to forests, mountains and the capital city. Here are fifty-one original poems, translated into and out of Welsh in an entirely bilingual poetry collection which explores where the A470 might take us. Travelling through memory, myth, love and grief, we learn lessons, ache for match tickets, stitch ourselves together and encounter famous goats. O bosib y ffordd fwyaf adnabyddus yng Nghymru, mae’r A470 yn ymestyn am 186 milltir o arfordir y gogledd i arfordir y de trwy ganol Cymru. Ar ei hyd gwelir traethau a chwareli, atomfa ac awyrennau rhyfel, mynyddoedd a’n prifddinas. Yn y gyfrol hon cawn 51 o gerddi gwreiddiol, wedi’u cyfieithu o’r Gymraeg, neu i’r Gymraeg, i greu casgliad dwyieithog sydd yn ein harwain ar hyd yr A470. Cawn ein tywys trwy atgofion, chwedlau, cariad a galar, dysgwn wersi, rhannwn docynnau gêm, pwythwn frodwaith ein gwlad a gwylio’r geifr.
