Transport Secretary Ken Skates has confirmed progress on a series of measures aimed at improving the resilience of transport links between Ynys Môn and the mainland, following recommendations from the North Wales Transport Commission (NWTC).
The latest update outlines several key areas of work focused on strengthening the Britannia Bridge and improving traffic management across the Menai Strait. Around £1 million will be invested over the next two to three years to deliver the proposals.
Wind Deflectors on Britannia Bridge
A study has found that installing wind deflectors on Britannia Bridge would substantially reduce traffic restrictions caused by high winds. The measure is expected to increase the bridge’s operational capacity and lessen reliance on the Menai Suspension Bridge as a diversion route.
Key stakeholders have expressed support for the proposal, and detailed work will now begin, including structural surveys, heritage assessments, and detailed design development.
Highway Alignment, Traffic and Speed Management
Options for improving traffic flow and safety on the bridge and its approaches were assessed, with analysis showing that variable speed limits could reduce collisions and improve journey reliability.
An upgrade of the existing traffic management equipment will now proceed alongside the introduction of variable speed limits. As an immediate step, new road markings and signage will be installed between the Junction 9 roundabouts to improve lane discipline.
Three-Lane Tidal Flow System
Further studies have been commissioned into a possible three-lane tidal flow system on Britannia Bridge. Modelling suggests it could ease congestion and improve journey times, though it would require a 30 mph speed limit and narrower lanes, with the centre lane restricted to light vehicles.
While the idea shows potential, further safety and risk assessments will be carried out in collaboration with key stakeholders before any decision is made.
Active Travel Route and Bus Priority Measures
Options for introducing a walking, cycling and wheeling route across Britannia Bridge were reviewed but ruled out due to high costs, low projected use, and technical challenges.
Meanwhile, Transport for Wales will continue developing bus priority measures across the Menai Strait — including potential bus lanes, bus gates, and improved walking and cycling links – as part of the wider North Wales Bus Infrastructure Enhancement programme.
Focus on Practical Improvements
Mr Skates said these short- and medium-term measures represent the most practical next steps for strengthening the Menai crossings.
“While we have not ruled out a third crossing in the future, we believe more can be done now to improve the resilience of the Britannia Bridge and the vital connections between Ynys Môn and the mainland,” he said.
