Faint fydd y gostyngiad yn lefel y traffig ar yr M4 yng Nghymru o ganlyniad i gynigion y Llywodraeth i gau cyffyrdd, a) mewn termau absoliwt; a b) mewn termau canrannol?
The report published alongside my Oral Statement of 6 October estimates that the option involving changes to the existing M4 and its management, including junction closures, could reduce traffic on limited sections of the M4 around Newport by up to 3%. The report does not provide an equivalent estimate in absolute vehicle numbers.
It also makes clear that any traffic and performance figures should be regarded as indicative and that further appraisal, modelling, impact assessment and engagement would be required before any decisions are taken.
As I announced on 6 October, no decisions have been taken on any specific interventions. Further work will be undertaken to develop options, assess their impacts and engage with local communities, businesses and other stakeholders before any future decisions are made.
