Twists and turns in the Taff Valley
Built in the 1970s, the A470's high speed expressway down the Taff Valley to Cardiff swings you around endless corners as it finds its way through towns, villages, steep wooded hillsides, railways, rivers and bridges.
This video was filmed on 20 June 2009. The A470 hasn't changed dramatically since then, but fifteen years ago it did still have some of its original seventies features - most noticeably all those huge streetlights painted pastel green.
Our guide to the A470 is in the Motorway Database.
