One of the most important roads in Wales, the A55 is second only to the M4, providing a lifeline to the densely populated North Wales coast and connecting the port of Holyhead to the trunk road network across the English border.

A55 Third Menai Crossing 31 October 2017

Provision of extra road capacity for the A55 across the Menai Strait between the Welsh mainland and Anglesey. At present, the A55 forms a continuous and mostly grade-separated expressway from Chester to Holyhead, except at the Menai Strait where it reduces to a single two-lane road to cross the Britannia Bridge. The scheme aims to provide two lanes in each direction at this crossing.

A55, A494 and A548 Deeside Corridor 25 October 2017

A new route, consisting partly of an entirely new dual two-lane road and partly an upgrade to the existing A548, between the A55 at junction 33 (the A5119 at Northop) and the A494/A550 junction complex at Shotwick, intended to relieve the existing A494 and A55 between those points. The new dual carriageway will run from the A55 at junction 33 to Connah's Quay Power Station. From that point, the A548 will be upgraded to form a free-flowing expressway with grade-separated junctions, crossing the Flintshire Bridge, with a new direct connection to the A494 at Shotwick leading to the M56.
