A55

Upgrade works at junctions 15 (Llanfairfechan Roundabout) and 16 (Puffin Roundabout, Penmaenmawr) to replace the existing roundabouts with grade-separated interchanges, allowing uninterrupted free-flowing travel on the A55. The scheme will result in an uninterrupted expressway from the end of the M56 north of Chester to the Britannia Bridge west of Bangor.

Multiple options are under consideration for each junction. Preferred options are expected to be published in summer 2019, and a statutory enquiry will then follow.

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.

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.
