Two possible routes under consideration for new M4 – A48 Link Road

Two possible routes for a new road linking the M4 with the A48 and Cardiff Airport have been unveiled following work undertaken for the Vale of Glamorgan Council and funded by Welsh Government, along with proposals for a new railway station and park and ride facility.

The routes, which would also connect junction 34 of the motorway with strategic employment sites in the Vale, are being presented as part of a public consultation exercise designed to get feedback on the possible options.

The scheme would improve access from the M4 and the valleys into the heart of the Vale and Western Cardiff along with Cardiff Airport and the surrounding enterprise zone and unlock further economic development in the area.

Both routes would connect just south of junction 34 of the M4 to the A48 at Sycamore Cross and would utilise a section of existing road to minimise impacts on nearby woodland.

One would bypass the village of Pendoylan to the east, while the other route would bypass Pendoylan to the west.

The proposed route to the East of Pendoylan.

The estimated costs for each scheme are £81.025 million and £58.666 million respectively. The eastern route is potentially more expensive given the need to take account of the floodplain.

Both would be single carriageway roads and would include segregated walking and cycling lanes and would allow for a new railway station and park and ride facility to be built close to junction 34, at an additional cost of around £25m.

Cllr John Thomas, Leader of the Council, said: “Our goal is to make the Vale of Glamorgan a more attractive place to live, work, and do business. This scheme will achieve not only this but also bring huge benefits to the wider economy.

“Cardiff Airport is of great national significance and its growth and future success, together with the Enterprise Zone, will be vital in fuelling economic development in South Wales.

“Both of the proposed routes would also make a real difference to the lives of those living in this part of the Vale. The lack of an appropriate transport link between the M4 and A48 has turned the roads connecting Pendoylan and the surrounding villages into rat runs for commuters. This is not good for anybody. The current road is also unfit for cyclists and pedestrians.

“We have already worked closely with local communities, via our appointed consultants, Arcadis, to draw up these initial proposals. Now we want to hear the views of as many people as possible to help decide the best way forward.”

Residents and other interested groups are being encouraged to find out more about the proposals and have their say online via the Council’s website. The plans, full consultants’ report, and consultation response form can all be found at

Plans will also be on show to the public for the next four weeks. Initially at locations close

to the proposed routes – the Vale Hotel and Resort at Hensol on 17 April and Cottrell Park Golf Club on 18 April – and then at the Vale of Glamorgan Council offices.
