A5 – Bangor to Chirk Trunk Road


The A5 London to Holyhead road is a route of national historic significance and interest, being particularly linked with Thomas Telford who was responsible for its design and construction across the North Wales region. The section of A5 which remains as a trunk road runs from Bangor in the north west through to Chirk in the south east of the region.

Historically the A5 was the main road link between the Midlands and North Wales. Since completion of the A55 however, the priority of this route in strategic terms has reduced. Although not on the trunk road core network, it is a route of regional significance as a major tourist link to the North Wales area, and as a major local distributor route. It links the Llangollen area and the A483 in the east with Betws-y-Coed, Snowdonia and ultimately Bangor in the west.

The A5 carries significant levels of tourist traffic during the summer period and some commuter traffic in localised areas. It also provides a corridor for public transport, serving the surrounding towns and villages, rural businesses, schools and leisure activities with a high historic, landscape and biodiversity value.

The A5 corridor is predominantly single carriageway standard throughout.
