A494 – Dolgellau to Queensferry Trunk Road


The A494 trunk road runs diagonally across the North Wales region, and comprises two distinct sections.

From its junction with the A470 in the south west at Dolgellau, crossing the A5 at Corwen, to the A55 at Ewloe in the north east it is predominantly single carriageway.

To the north east of the A55, the A494 forms part of the high standard dual carriageway route through Queensferry to the M56. This route serves major centres such as Dolgellau, Bala, Mold, Ruthin and Queensferry.
