This project is under review

This project is currently being considered as part of the roads review.

Why we are doing it

Nantycaws is a mid-point between Cross Hands and Carmarthen. These changes will improve the junction and will help us to improve other junctions along the A48.

The current junction:

  • has a high collision rate
  • has many points where vehicles have high-speed road traffic accidents
  • has poor access to local facilities such as service station/café and recycling centre
  • doesn’t offer opportunities to cycle or walk safely
  • support for public transport could be improved as there are  currently safety issues for buses.

We want to:

  • make the junction safer for all road users providing a safer junction for drivers and buses
  • make it easier for pedestrians and cyclists crossing the A48.

Current progress

The project is at stage 2 of the Welsh Government Transport Appraisal Guidance (WelTAG), after being part of a corridor stage 1 study which included the whole A48 corridor between Cross Hands and Carmarthen.

This stage will involve:

  • establishing a preferred option
  • environmental surveys
  • assessment of impact of the improvements
  • consulting with local stakeholders.


WelTAG 1 report published: early 2022
WelTAG Interim 2 report being finalised: early 2022
Detailed design development expected: 2022

Next steps

Once we have decided on a preferred concept we will develop the study through WelTAG stage 3.

What we are doing

We want to merge smaller junctions in the Nantycaws area into one purpose built junction. This single junction will be safer and more accessible for all road users.

How we are consulting

We have been consulting with local businesses and landowners in the area. We have also been working with:

  • Carmarthenshire County Council
  • community councils
  • emergency services
  • other interest groups (such as Sustrans).

Wider consultation will take place once we have developed a preferred concept to help inform the detailed development.
