The Welsh government has closed the Menai Suspension Bridge, a 200-year-old vital link between Anglesey and mainland north Wales, on Saturday, October 4, 2025, at 14:00 BST. Engineers discovered faulty bolts in the bridge’s beams, necessitating immediate closure for safety reasons, as ordered by the Welsh government. Motorists are being diverted to the Britannia Bridge, which handles 36,000 vehicles daily compared to Menai’s 13,300, leading to congestion and delays of up to 30 minutes, particularly during busy periods like ship arrivals at Holyhead. After recent structural inspections conducted during Phase 2 works by UK Highways A55 DBFO Ltd, the organization responsible for maintaining and operating the bridge, engineers advised imposing an immediate 3-tonne weight limit for cars and motorcycles, along with enforcement measures. This action comes in response to the need to replace bolts on key beams beneath the bridge. This decision comes after UK Highways A55 DBFO Ltd highlighted difficulties in enforcing the 3-tonne weight limit, which could compromise the bridge’s safe operation. Previous enforcement of the 7.5-tonne limit saw instances of non-compliance, with HGVs and coaches ignoring the weight restrictions. Provisions are in place to ensure emergency service vehicles can access the area if the Britannia Bridge is affected by high winds or other incidents. North Wales Police have confirmed they will assist in any emergencies requiring vehicles under 3 tonnes to use the Menai Suspension Bridge.

The Welsh government, through Transport Secretary Ken Skates, apologized and prioritized safety, with ongoing maintenance (phase two, including repainting) set to continue until spring 2026. Businesses are encouraged to seek support through Business Wales and UK rates relief schemes, with some eligible for 100% non-domestic rates relief. Medi has called for a resilience fund to support affected communities, while further investigations aim for a swift resolution.
