Temporary traffic arrangements to be introduced as scaffold structure is lifted for underdeck maintenance
WORK on the historic Menai Suspension Bridge is set to enter another key stage next week, with temporary tidal traffic management planned to allow engineers to continue major maintenance.
The Welsh Government confirmed that the latest phase of work on the bridge’s crossbeams has been successfully completed. Contractors will now begin lifting the large scaffold structure, known as the Aerotruss, to the bridge’s underdeck.
To enable the operation, a tidal-flow traffic system will be introduced from March 9 for around six days while equipment is prepared and installed for underdeck painting and bearing maintenance.
Under the temporary system, vehicles will be able to travel from Anglesey to the mainland between 7am and 1pm. Traffic heading from the mainland to Anglesey will be allowed to cross between 1pm and 7pm. Overnight, from 7pm until 7am, normal traffic signals will be in place.
Pedestrians will still be able to use the east footpath throughout the work, although people are being asked not to stop while crossing the bridge. Marshals will be on site during the installation period, and cyclists are being reminded to dismount when using the footpath.
The scaffold lift will also involve activity on the water below the bridge over several days, including trial runs, and is subject to weather conditions.
Officials say the wider second phase of the project has been revised to minimise disruption. Traffic management will only be required for short periods to complete key elements of the work, significantly reducing the impact on residents, commuters and businesses compared with earlier plans.
A 7.5-tonne weight restriction will remain in force while the work continues to ensure the safe operation of the bridge.
Cabinet Secretary for Transport and North Wales Ken Skates said he was pleased to see the project progressing.
“I’m pleased the work on the crossbeams has been completed successfully. Work now progresses to the next stage and I’d like to thank residents, commuters and businesses for their continued patience and co-operation.”
