Newport Labour group has backed plans to remove the Old Green roundabout as part of a wider package of transport improvements.
Councillor Rhian Howells, cabinet member for assets and infrastructure at Newport City Council, set out the authority’s position in January.
She represents the Tredegar Park and Marshfield Ward, which includes Duffryn, as a Labour councillor.
The proposals form part of the Burns package designed to tackle M4 congestion.
Councillor Howells stated that this congestion represents a significant obstacle to economic growth in Newport and the surrounding area.
Welsh Government has pledged substantial investment in the Burns schemes.
The Burns Commission report indicated that implementing these measures would ease traffic flow on the M4 and improve movement throughout the city.
Councillor Howells emphasised that delivering the full range of Burns measures is essential for the Old Green plans to achieve their intended purpose.
The council is actively advocating for complete implementation at both regional and Welsh Government levels.
Former council leader Councillor Jane Mudd voiced strong support when the proposals were initially presented in 2023.
She indicated that building a stronger, greener Newport was a priority and that improving access to public transport and active travel options would help reduce car dependency while bringing lasting change to the city.
Newport Conservative Councillor Ray Mogford has sought clarification on several points.
He noted that current council chief executive Beverly Owen served on the Burns Commission board as one of eight commissioners.
Councillor Mogford pointed out that Ms Owen was the official representative for the local authority, though she maintains political neutrality.
Among the questions raised were whether Ms Owen represented Newport residents, the extent of her communication with then council leader Jane Mudd, and whether any objections or concerns were raised regarding the roundabout removal.
The debate over the Old Green is expected to continue.
Local residents will have an opportunity to express their views during next May’s council elections.
