Not Devolved
The powers over this are reserved to the UK Parliament in Schedule 7A of the Government of Wales Act 2006 (Specific Section/Number/Clause).
The Menai Bridge is 200 years old, while the (rebuilt) Britannia Bridge is around 50 years old. The Menai Bridge is showing its age, while both bridges fall short of modern trunk road standards.
In 2017, the Welsh Government drafted proposals for a third road bridge across the Menai Straight (“Third Menai Crossing”).
The preferred option was a bridge built east of the Britannia Bridge to carry the eastbound carriageway of the A551. Plans for a third crossing were dropped in 2023 under the previous Welsh Government’s new transport policy (“Llwybr Newydd”). This policy presumes against building new roads, opting to favour public transport improvements.
In 2022, the Welsh Government announced a programme of repairs to the Menai Bridge across two phases2, which requires its closure for certain periods. These are a mix of necessary structural repairs, and repairs associated with celebrating the bridge’s 200th anniversary.
The number and length of the closures have frustrated residents and businesses, though authorities have condemned abuse directed at bridge workers by drivers3.
A Commission was established to consider short-term and long-term options for the crossings, reporting back in December 20234.
In October 2026, the Welsh Government announced that planning would resume for a third Menai crossing, with tempoary measures put in place to each problems on the existing two bridges.
In addition to the problems associated with the bridge’s age, the Menai Bridge only has a single carriageway road. The A55 dual carriageway narrows to a single carriageway to cross the Britannia Bridge too. Add closures and restrictions due to roadworks and high winds, and the two crossings act as a traffic bottleneck.
The Menai Bridge also has a 7.5 tonne weight limit during the current roadworks programme. Every time a vehicle over this weight limit crosses the bridge, the bridge needs to be closed for safety inspections, causing further delays.
A private company, UK Highways A55 Ltd, is responsible for maintenance of the Menai Bridge. This is because the A5 loop was included in a Private Finance Initiative (PFI) contract signed when the A55 dual carriageway was built across Anglesey in the 1990s. This contract expires in 2028.
In December 2023, it was estimated that 43,000 vehicles use the two crossings each day. The majority of traffic uses the Britannia Bridge, though around 11,000 vehicles use the Menai Bridge.

What have ministers said?
What's being done about this?
Plaid Cymru’s 2026 manifesto included a commitment to re-examine plans for a Third Menai Crossing.
On 6th October 2026, the Deputy Minister announced that detailed planning for a third Menai crossing had restarted. This is now the Welsh Government’s preferred long-term option to solve traffic problems.
The Welsh Government has dropped proposals for a three-lane tidal flow system on the Britannia Bridge as it would make it less safe6.
The previous Welsh Government launched a programme of works on the Menai Bridge across two phases.
The first phase was completed in October 2024. Phase 2 began in January 2026 and is ongoing.
The Deputy Minister told the Senedd in June 2026 that the Welsh Government is in discussions with North Wales Police and the DVSA on stronger enforcement of the 7.5 tonne weight limit.
Improved signals and variable speed limits will be taken forward for the Britannia Bridge. This will manage traffic flows when either of the two bridges is closed or restricted. Wind deflectors are also set to be installed to reduce the need for traffic restrictions during high winds.
Traffic orders issued by the Welsh Government may be needed as the trunk road network in Wales is controlled directly by the Welsh Government (not local councils).
The current bridge repair works are expected to be completed by spring 2027.
The Deputy Minister has said that he expects a third Menai crossing to take “between 8 and 10 years” to be delivered, as a realistic timeframe (mid-to-late 2030s).
What have the Senedd's Committees said?
P-07-1594: “Build a new crossing over the Menai” (7,788 signatures)
Status: Closed
Debate: Held on 00/00/0000 (Transcript)
Following the Welsh Government’s announcement, the Committee agreed to close the petition as the announcement “ends all doubt”.
