Creating better social, economic and environmental outcomes for North Wales

2nd August 2019

A collaborative Corderoy and Capita Infrastructure team has been appointed as multi-disciplinary employers’ agents on Welsh Governments £250m A55/A494/A548 Flintshire Corridor in North Wales. The scheme will increase capacity along the existing A548 and includes modifications and improvements to junctions, as well as provide a new section of road between the A548 and the A55.

The scheme will play an important role in helping to relieve congestion in the North Wales area, accompanied by plans to minimise adverse impacts on the human environment including air, noise and light pollution, and landscape and townscape. This is alongside minimising adverse impacts on the natural environment, including local air quality, water and soil pollution, and biodiversity impacts.

A core part of the scheme is a new 13km two-lane dual carriageway, linking the A55-A5119 Northop Junction (Junction 33) with the A494 and A550 north of Deeside Parkway Junction, via Kelsterton Interchange and the Flintshire Bridge. Creating better outcomes, the scheme will aim to improve transport connections for businesses within the area to key economic centres and employment sites. This will in effect contribute to a reduction in journey time variability and enhance the transport network resilience of the A55 / A494 study corridor during periods of high demand, incidents and maintenance events.

The integrated Corderoy and Capita Infrastructure technical advisory team will act as the Welsh Government’s representative, providing effective and efficient financial, project management, contract and technical advice throughout the life of the project.

Ken Skates, Ministry for Economy & Transport in the Welsh Government, stated, “This scheme is of critical importance to North Wales and will relieve congestion in the area. This is alongside improving access to the Deeside Enterprise Zone and allowing the economy to grow and prosper, serving to protect the regional economy. Today’s announcement demonstrates our on-going commitment to it, and to improving transport infrastructure across the region.”

Construction is planned to begin in late 2022/early 2023, subject to completing the statutory process, which is likely to include a public local inquiry. The project builds on the success of the collaborative approach between the Capita Infrastructure and Corderoy teams which supported the delivery of the Welsh Governments £100m Newtown Bypass which opened in 2018.
