The £1.4bn Welsh Government funded project will improve accessibility, reduce journey times, provide extra resilience and reliability, and enhance road safety.

The A465 (Hirwaun to Dowlais) project when completed later this year will have delivered 17.7km of new dual carriageway, 6.1km of sideroads, more than 14km of active travel routes, 38 new culverts (a structure that channels water past an obstacle), 30 new bridges and 28 retaining walls.

As well as connecting communities by linking the Valleys, South and West Wales to the English Midlands and beyond, the scheme has also created significant opportunities for the local economy, including:

  • creating more than 2,000 new jobs with over half of those employed living in the local area
  • employing 158 apprentices with just under half from the valley’s region, helping to support education and skills training
  • supporting more than 66 community initiatives
  • spending more than £200m in the Valleys supply chain
  • delivering more than 22,000 hours of pupil engagement

As well as economic benefits the project has also created a series of environmental benefits. To mitigate ecological impacts a series of measures have been taken as part of the project. These include:

  • the relocation of species such as great crested newt and marsh fritillary butterfly and the creation of new habitats to support these alongside bats, dormouse and lapwing
  • relocating coppiced stools and topsoil from ancient woodland impacted by the project
  • planting more than 55,000 trees in the local area with a total of 120,000 expected to be planted by the end of the programme.

Speaking on a visit to the A465 project, Cabinet Secretary for Transport and North Wales, Ken Skates said:

“Fixing our roads is a key priority for us. We’ve spent £1bn fixing and improving our roads since 2021, including more than £250m in the past year.

“This project is an incredibly impressive piece of engineering and a fantastic example of how targeted investment in road infrastructure can deliver on many levels, providing jobs for the local community, improving accessibility, supporting education and skills, alongside delivering environmental benefits.

“It’s been a complex project which has not been without its challenges, and I would like to thank everyone who has played their part in helping us to deliver one of the largest road projects in the UK.”

Family run business owner, Tony Gibbons – Atlas Groundworks Ltd explains how the project has benefited his business:

"It has allowed us to upscale our operations and further strengthen our reputation in the construction industry. As a result of this we’ve been able to create new job opportunities for local people and enhance our skills so that we can expand our business services. I am very grateful to have been involved in this exceptional project.”

Tim Wroblewski, Associate Director and Principal Environmental Planner for TACP (UK) Ltd added:

“The project impacts sensitive habitats, species, and landscapes and through a series of innovative and best practice mitigation measures we’ve been working hard to ensure the project leaves a positive legacy on the environment.

“It is exciting to see our work starting to take shape with wildlife already making use of the new habitats we have installed.”
