M4 Congestion: First Minister Calls for Roads-Based Solution
6/1/2026, 8:33:48 PM
Core Event and Background
Welsh First Minister Rhun ap Iorwerth said “something has to be done” to ease bottlenecks around the Brynglas Tunnels on the M4 near Newport. He ruled out reviving the scrapped “black route” – a proposed motorway across the Gwent Levels – but pledged to pursue a “roads-based solution”. The scheme had an original price tag of £1.6 billion, now up to £2.5 billion, and already absorbed £157 million in planning costs.
Official Statements & Responses
Plaid Cymru leads a minority government, so Rhun ap Iorwerth must secure support from parties. Welsh Conservatives, via shadow minister Janet Finch-Saunders, demand a firm commitment to a relief road. Labour says the first minister makes promises without a detailed plan, while Reform UK backs a return to the original black-route concept. Welsh Green Party argues road building conflicts with climate goals, and MS Natasha Asghar urges delivery after “broken promise after broken promise”.
Cost & Feasibility
The black-route estimate of £1.6 billion has risen to up to £2.5 billion, a sum that would consume most of the capital budget. £157 million in planning was spent before the 2019 cancellation. No timetable has been published, and the first minister has not confirmed whether a “blue route” upgrade, a new Menai Strait crossing, or another option will be pursued.
Conflicting Reports & Gaps
Sources differ on the projected cost, citing the original £1.6 billion figure and a later estimate of up to £2.5 billion. No implementation timetable or definitive scheme has been disclosed.
Criticism & Opposition
Environmental groups note Gwent Levels are protected and warn a £2.5 billion road could jeopardise biodiversity. The Welsh Greens argue road building conflicts with climate goals, while opposition parties highlight the fiscal risk of a project that could absorb the capital budget. Critics say vague promises do not address these environmental, financial challenges.

Next Steps
A resilience report on the M4, A55 and A494, commissioned by former Labour transport secretary Ken Skates, will guide future investment. The first minister’s team will evaluate upgrades to existing routes, the feasibility of a blue-route alternative, and possible new Menai Strait crossings. Advancing any proposal will need coalition support in the Senedd.
