The A470, also known as the Cardiff to Glan Conwy Trunk Road, is the major long-distance road in Wales, from Cardiff on the south coast to Llandudno on the north coast. It is long, and has undergone considerable road improvement in the last two decades. While previously one had to navigate the narrow roads of Llanidloes and Dolgellau, both these market towns are now bypassed due to extensive road modernisation.
