Pa waith newydd y mae Llywodraeth Cymru wedi'i gomisiynu ers 13 Mai 2026 i ganfod datrysiadau i dagfeydd yn nhwnneli Brynglas yng Nghasnewydd?
Already underway is a short, focused programme of work to explore realistic options across road, rail and bus interventions. The emphasis is on measures that are practical, deliverable and capable of making a meaningful difference in the near to medium term. This work will draw on the substantial evidence base already available and focus on identifying practical and deliverable options. I will report back to Members on the outcome of this work in Plenary in the autumn term, setting out the Government’s intended way forward.
The above work is separate from the work which will be commissioned to examine the resilience of the wider M4 corridor across Wales. (Saesneg yn unig)
