A55 road

Résumé
The A55, also known as the North Wales Expressway (Gwibffordd Gogledd Cymru), is a major road in Wales and England, connecting Cheshire and north Wales. The vast majority of its length from Chester to Holyhead is a dual carriageway primary route, with the exception of 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 apart from a roundabout east of Penmaenmawr and another nearby in Llanfairfechan. Initially, the road ran from Chester to Bangor. In 2001, it was extended across Anglesey to the ferry port of Holyhead parallel to the A5. 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 begins at junction 12 of the M53, the southern end of the motorway, near Chester. It is known as the Chester southerly bypass between J39 Christleton and J36a Broughton. The A55 crosses the River Dee and the border into Wales, passing close to Broughton, Flintshire, and passing north of Buckley, Penyffordd and Northop. There is a major climb between Broughton and Dobshill (Junctions 36a Broughton to 35 Dobshill) though with no crawler lane. Junction 34/33b is point at which the A494 converges and then diverges with the A55. The road briefly has a three-lane section as westbound traffic from Queensferry can leave towards Mold. In the eastbound direction another short three-lane section allows vehicles to join the A494 or exit onto the A55 to Chester. Traffic taking the A55 into England must negotiate a tight 270 degree speed-limited single lane curve to climb up and over the A55/A494 at Ewloe loops. Plans to upgrade the A494 between this junction at Ewloe and Queensferry were rejected by the Welsh Government on 26 March 2008 due to their scale.
