Why we are doing it

The planned improvements will help improve network resilience. It will:

  • reduce variation in journey time between Culverhouse Cross and Cardiff Airport Enterprise Zone
  • reduce variation in journey time between Culverhouse Cross to St Athan Enterprise Zone
  • discourage traffic from using alternative routes to the enterprise zones
  • improve access to the enterprise zones for public transport, pedestrians and cyclists

Current progress

The Vale of Glamorgan Council approved the principle of the scheme in October 2015.The council submitted planning application for the scheme in March 2016. They appointed Capita as Employers Agent for the scheme, and Bruton Knowles as land agent. The Cabinet Secretary for Economy and Infrastructure confirmed the Compulsory Purchase Order in June 2017 following a Public Inquiry. The Works are progressing well and on target for completion in Summer 2019.

The works

We plan to build 4km of new road, east of the existing A4226. This new stretch of road will start near the Amelia Trust Farm. It will rejoin the A4226 near the River Weycock Bridge and the Welsh Hawking Centre.

There will be 2 new junctions to reach settlements to the west of the new stretch of road, and 1 junction to the east.

You can find more details about the scheme on the Vale of Glamorgan Council planning portal.
