Written Statement - M4

Edwina Hart, Minister for Economy, Science and Transport

Addressing the capacity and resilience issues on the M4 around Newport is the top 
transport challenge that we face in ensuring that Wales has an effective economic 
infrastructure which improves our competitiveness and access to jobs and services.  

Following Cabinet discussions earlier this week, I am therefore pleased to announce the next steps in relation to the M4 corridor in south east Wales.

As a result of ongoing discussions with the UK Government there has been a significant change in the assessment of the affordability of a major enhancement of the M4.

Building on the extensive development and consultation work undertaken on M4 Corridor Enhancement Measures (CEM), we will be consulting formally over the summer with Natural Resources Wales in order to go out to public consultation this September with a finalised draft Plan and Strategic Environmental Assessment (SEA) Report.

If implemented, the draft plan would lead to a motorway being built south of Newport.
