The Leader of the Vale of Glamorgan Council, Cllr John Thomas, and Cabinet Secretary for Economy and Transport, Ken Skates AM, today officially marked the beginning of construction with a turf cutting at the site. 

Five Mile Lane - JT & KS breaking groundCllr Thomas said: “Today marks a significant milestone for economic development in the Vale of Glamorgan. This is a scheme of great importance, not just because of the £25m investment but because of the huge potential benefits it offers both the Vale and South Wales as a whole.

“When completed the new road will significantly cut journey times for local residents, but more importantly will also reduce those between Culverhouse Cross and both the Cardiff Airport and St Athan Enterprise Zones. This will provide a vital stimulus to investment in both.
“The upgraded road will also bring improved public transport options and a safe cycling route”



Ken Skates said: “We are funding this vital piece of civil engineering to help the Vale of Glamorgan council improve the A4226, or Five Mile Lane, to better the access and journey time to Cardiff Airport and St Athan Enterprise Zones.
“The work will increase safety and journey time reliability along this section of the highway, and all routes to Cardiff Airport from the West, either via the A48 or the A4232, will benefit.”

Detailed design work for the project is currently being finalised by lead contractor Alun Griffiths.

Alun Griffiths' Project Manager said: “We look forward to leaving a legacy to improve the strategic network for St Athan within an area that our staff either work, live or use.”

The contract was awarded by the Vale of Glamorgan Council in October and formally agreed in December 2017.

Preparatory works, including some land clearance, began in early 2018 and the site compound from which the scheme will be managed was put in place earlier this month.
