The A55, also called the North Wales Expressway (Welsh: Gwibffordd Gogledd Cymru)[1], is an important road in Great Britain. It goes between Chester, England and Holyhead, Wales. It goes along the north coast of Wales for most of its route. For most of the route, it is a dual carriageway. Many parts of the road act like a motorway.

It is also part of the European route E22, which links to Amsterdam, Riga, and Moscow. The route once went between Bangor and Chester, but was extended to Holyhead in 2001. This links to the Republic of Ireland through the Port of Holyhead. In total, the road is 87 miles (140 km) long.[2]

Notes
  • Data from location marker posts are used to provide distance and carriageway identification information. Where a junction spans several hundred metres and the data is available, both the start and finish values for the junction are shown.[6]
  • Totso = "Turn off to stay on" meaning that the driver must leave the main carriageway to stay on the specified (A55) route.
