Which junctions between junction 23 and junction 30 on the M4 are being considered for closure?
Answered by Deputy Minister for Transport | Answered on 19/06/2026
On 9 June, I announced a short, focused programme of work to explore measures that could make a meaningful difference to conditions on the M4 around Newport, including the potential closure of certain junctions. This work will build on the substantial body of evidence already developed by previous governments on this issue.
I will report back to Members in the autumn term, setting out the outcome of this work and the Government’s proposed way forward.
