M4 Corridor Enhancement Measures Programme : Magor to Castleton (M4 CEM)

This website is now closed. Please refer to the Welsh Government’s website www.gov.wales/m4newport for the latest information on this project.

TM4 01he M4 Magor to Castleton, Corridor Enhancement Measures Programme (M4 CEM) was set up to explore and resolve issues of capacity, safety and resilience along the M4 corridor in south-east Wales.

On 26 June 2013, Edwina Hart AM CStJ MBE, Minister for Economy, Science and Transport, published the following written statement on behalf of the Welsh Government:

“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.”

Details of when the Public Consultation will begin will be released by Welsh Government in due course.

M4 Corridor Enhancement Measures (CEM) Participation Report

The Minister’s Written Statement of 26 June 2013 on the M4 refers to building on the extensive development and consultation work undertaken as part of the M4 Corridor Enhancement Measures (M4 CEM) Programme. A key part of this work was the consultation exercise, which sought views on a range of possible options and ran from March until July 2012. The results of the M4 CEM public consultation are reported in the M4 CEM Participation Report, which can be downloaded below. The consultation responses, in addition to the wider engagement and consultation that helped shape the development of the M4 CEM Programme, has helped inform the development of an M4 Corridor around Newport draft Plan and therefore remain of relevance moving forward. The draft Plan, which will present the Welsh Government’s preferred strategy for addressing problems of capacity and resilience on the M4 Corridor around Newport, will be subject to public consultation from September 2013, alongside a Strategic Environmental Assessment (SEA) and other associated assessments.
