The A470 (also named the Cardiff to Glan Conwy Trunk Road)[1] is a trunk road in Wales. It is the country's longest road at 186 miles (299 km) and links the capital Cardiff on the south coast to Llandudno on the north coast.[2] 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[when?]. The 26 miles (42 km) from Cardiff Bay to Merthyr Tydfil are mainly dual carriageway, but most of the route from north of Merthyr to Llandudno is single carriageway.
