A55 road: Meaning (information, definition, explanation, facts)

The A55, also known as the North Wales Expressway, is a major road in Britain. Its entire length is a dual carriageway primary route, with the exception of the point where it crosses the Britannia Bridge over the Menai Strait.

It runs west from its junction with the M53 motorway near Chester, crossing the Welsh border and passing north of Buckley and south of Flint and Holywell. It then bypasses St Asaph, and running along the North Wales coast passes Abergele, Colwyn Bay, Conwy, Penmaenmawr and Llanfairfechan before heading onto the island of Anglesey, where it ends in Holyhead
