THE WELSH GOVERNMENT is to begin detailed work on options for a third Menai crossing, while ruling out a return to the controversial M4 Black Route around Newport.
Deputy Transport Minister Mark Hooper MS told the Senedd that repeated closures of the Menai Suspension Bridge had exposed wider problems with the resilience of Wales’ transport network.
The bridge, which is around 200 years old, has been hit by closures after drivers ignored a 7.5-tonne weight limit. Ministers say each breach requires precautionary inspections, causing further disruption.
Works to stabilise and preserve the bridge, including repairs to crossbeams, bolts and other structural components, are expected to continue until spring 2027.
Mr Hooper said the Welsh Government was working with North Wales Police and the DVSA on stronger enforcement.
Third crossing back on table
The minister said the Menai crossings must be treated as one system, with Britannia Bridge carrying most traffic but vulnerable to high winds, while the Menai Suspension Bridge has lower capacity and ongoing maintenance needs.
He confirmed that work would now begin on “detailed options” for a third Menai crossing, building on previous studies.
The move marks a significant shift after earlier plans for a third crossing were scrapped following the Welsh Government’s roads review.
M4 plan due in autumn
Mr Hooper also confirmed a new short programme of work on the M4 corridor around Newport, one of Wales’ busiest and most congested roads.
However, he said the Government did not believe the previously proposed Black Route was “a credible option”.
Instead, ministers will look at road, rail and bus measures, including public transport alternatives, targeted improvements to the existing road network, and better links between strategic and local transport.
The minister said he would report back to the Senedd in early autumn with the Government’s intended way forward.
He said both the Menai crossings and the M4 showed the challenge of managing ageing infrastructure under increasing demand.
