The A55, also known as the North Wales Expressway (Welsh: Gwibffordd Gogledd Cymru) and the Chester to Bangor Trunk Road,[1] 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 and several short sections where there are gaps in between the two carriageways. All junctions are grade separated except for two roundabouts — one east of Penmaenmawr and one in Llanfairfechan. The road originally ran from Chester to Bangor but was extended parallel to the A5 across Anglesey to just outside Holyhead Docks in 2001. The road improvements have been part funded with European money, under the Trans-European Networks programme, as the route is designated part of Euroroute E22 (Holyhead - Leeds - Amsterdam - Hamburg - Malmö - Riga - Moscow - Perm - Ekaterinburg - Ishim). The A55 is sometimes called a motorway, because of its appearance, although it is not officially a motorway.
