A5 Menai Suspension Bridge – Hanger Replacement Programme FAQs

Aerial view of Menai Suspension Bridge A5

This project will include replacing the hangers on Menai Suspension Bridge. There will be a 7.5t vehicle weight restriction on the bridge from 5am 2nd June 2022.This will improve safety on this part of the network and reduce the risk of unplanned closures.

For more information about traffic management see the details below 

A 7.5t weight restriction will be in place on the bridge as a precaution. Restricted vehicles will be diverted via the A55 Britannia Bridge. Further details about the hanger replacement will be published as soon as possible.

Unfortunately buses will not be able to travel on this route while the weight limit is in place. Gwynedd County Council and Anglesey County Council will develop revised timetables and routes.

Further information can be found at Traveline Cymru - Journey Planning Wales.

The lane closure and traffic lights will be removed once the weight restriction is in place. Further lane closures will be needed during repair works and the hanger replacement. These will be advertised closer to the time. 

Every effort will be made to plan these lane closures outside of peak hours wherever possible to minimise disruption. 

Ambulances and police vehicles will still be able to travel over the bridge. Fire Engines will not be permitted as they weigh over 7.5t. The fire service has been informed and are building this constraint into their operational plans.
