The mystery of the missing A470

"Last year, we travelled the length of the A470 from just south of Llandudno back to the Radyr exit. It’s a fantastic journey. Virtually the whole length, at least as far south as Merthyr, has amazing scenery. It’s the sort of road that’s a pleasure to drive, and there aren’t many like that these days. There should be a song about it, like Route 66 or Highway 61. The Wales Tourist Board should be promoting its virtues."
