Extra measures are being put in place to ensure the Menai Suspension Bridge stays open during the Urdd National Eisteddfod.

The bridge was closed twice in quick succession on Wednesday after it was crossed by two overweight vehicles, including a bus.

It was also closed for more than three hours on Tuesday morning following another unauthorised crossing by an overweight vehicle, leading to major tailbacks on the A55 and the A487 around the Britannia Bridge.

The Welsh Government says it understands the “frustration caused by the closures…during this busy time”.

As of Wednesday evening, temporary traffic lights are in place and any vehicles over the 7.5 tonne limit will be turned away by officers.

A Government spokesperson added: “Those who fail to comply will be referred to the police, and we will increase police and Welsh Government Traffic Officer presence to support compliance.”

“We would urge members of the public to respect those working on the bridge and to follow their instructions.”

They added: “Improving resilience across the Menai Strait remains a key priority for Welsh Government as part of our wider transport and economic ambitions.”

The bridge was closed at around midday following the first authorised crossing and reopened within the hour, only to close again at around 1.30pm when the weight restrictions were breached by a coach.

Speaking at the Urdd Eisteddfod on Tuesday, First Minister Rhun ap Iowerth said a third road crossing over the Menai Strait was an “obvious solution”.

Helen Jenner, deputy leader of Reform UK in Wales, said she was personally in favour of a third Menai crossing, telling BBC Cymru Fyw that ‘something needs to happen’ to solve the problem.
