What we are doing

UK Highways A55 Ltd are replacing hangers on the A5 Menai Suspension Bridge.

Why are we doing it

We need to improve the bridge’s safety.

Next steps

Works to replace the bridge hangers started on 4 September 2023. Other essential work to bring the bridge back into full use are also taking place.

The construction programme has been developed by UK Highways A55 Ltd. They operate and maintain the bridge on behalf of the Welsh Government through a Private Finance Initiative (PFI) Design, Build, Finance and Operate (DBFO) Contract. The plans have been discussed with stakeholders.

We do not intend to close the bridge completely during the works. The works have been designed so that one lane will remain open at all times. The lane will have traffic lights to enable traffic to continue to cross the bridge in both directions. The lane closure and traffic lights will be in place from 7am Mondays to 3.30pm Fridays.  The traffic lights will be manually operated during peak times, so traffic can be managed as efficiently as possible while the works takes place. The lights and lane closure will be removed for weekends.

It is expected that all the required works will be completed by the end of August 2025 (subject to weather). This will ensure the Menai Suspension Bridge is ready for its 200th anniversary in 2026.

To complete the work by this deadline, works will need to take place during holiday periods, including Easter, school half terms and the summer holidays. This will allow the works to be completed as soon as possible and minimise the impact of weather delays on the programme by working at times with traditionally better weather. No works will take place during the Christmas holiday period or on Bank Holidays.

The Menai Suspension Bridge will still have a 7.5t weight limit in place while the work is under way. Once the works have been completed, the 7.5t weight limit will be removed.
