JUNCTION 28 of the M4 at Tredegar Park, Newport, will be upgraded as part of a series of key road improvements announced by economy, science and transport minister Edwina Hart.

Details of the scheme, including timescale and cost, have yet to be published.

But Ms Hart, in a statement to the Assembly, said improvements at the junction - along with a link road scheme in Cardiff Bay - are vital to improving transport links in South Wales.

She also reiterated plans announced late last month “to consult on a draft plan and associated assessments for the M4 corridor around Newport in September, that, if implemented, would lead to a motorway being built to the south of Newport.”

This, she added, is vital to “addressing capacity and resilience problems on this key artery, widely recognised as essential to support the Welsh economy.”

Her statement also emphasised the importance Ms Hart places on improvements to the Heads of the Valleys Road.

“The A465 remains a priority and I will progress the remaining phases of the dualling in view of the route’s strategic importance for the Upper Valleys, Ebbw Vale Enterprise Zone and as an national and international link,” she said.

“Transport has a critical role to play in improving Wales’ economic competitiveness and provides enhanced access to jobs and services.

“I recognise that in thinking about transport we must focus on how it can serve the needs of businesses, people and communities.

“It is my intention to ensure that Wales has excellent national and international connections, enabling access to markets, to employment, education and services. I also believe that providing affordable, effective and efficient transport systems can play an important role in helping to tackle poverty.

Ms Hart said she recognises that progress “will be subject to statutory consents and funding availability” but is looking for “maximum value for money and impact from this investment.”
