Mae peirianwyr strwythurol wedi cadarnhau y dylai Pont Menai gau i unrhyw draffig er mwyn caniatáu i waith cynnal a chadw hanfodol gael ei wneud. Bydd hyn yn digwydd o 14:00 ddydd Gwener 21 Hydref.


Cafodd y cyhoeddiad ei wneud yn dilyn profion diweddar ar hangeri presennol y bont.


Fel rhan o waith parhaus UK Highways A55 i gynnal a chadw Pont Menai, nodwyd y byddai angen cynnal rhagor o brofion ar y bont yn ogystal â gosod hangeri newydd yn lle rhai o’r hen rai.


O ganlyniad i ymchwiliadau pellach, mae risgiau difrifol wedi’u nodi ac mae peirianwyr strwythurol wedi argymell cau Pont Menai i unrhyw draffig. Mae'r canfyddiadau arweiniodd at yr argymhelliad i gau'r bont yn cael eu hadolygu ar hyn o bryd, a gallai hynny gymryd hyd at bythefnos. Mae'r opsiynau sydd ar gael i ailagor y bont cyn gynted â phosibl wrthi’n cael eu hasesu.


Efallai y bydd angen cryfhau'r hangeri dros dro er mwyn sicrhau diogelwch ac uniondeb Pont Menai. Gallai'r rhaglen hon gymryd rhwng 14\-16 wythnos, gyda'r bont yn ailagor ar ddechrau 2023\.


Yn y cyfamser, bydd traffig yn cael ei ddargyfeirio at Bont Britannia.


Yn dilyn trafodaethau gydag UK Highways a’u harbenigwyr strwythurol, mae’r droedffordd ar draws y bont wedi’i hailagor i gerddwyr a beicwyr sy’n dod oddi ar eu beiciau.


Rhaid i bobl aros ar y llwybrau cerdded a bydd niferoedd yn gyfyngedig. Bydd Marshalls yn eu lle o ddydd Gwener, Hydref 21 tan ddydd Llun, Hydref 24 i reoli llif cerddwyr a bydd monitro yn cael ei roi ar waith i sicrhau cydymffurfiaeth wrth symud ymlaen.


Mae cynlluniau wedi’u trafod gyda phartneriaid gan gynnwys Llywodraeth Cymru, UK Highways A55, Asiant Cefnffyrdd Gogledd a Chanolbarth Cymru, y Gwasanaethau Brys a'r awdurdodau lleol.


Mae Llywodraeth Cymru’n datblygu strategaethau pellach i gynyddu cadernid Pont Britannia i liniaru'r risg o orfod cau’r ddwy bont mewn amgylchiadau eithriadol. Yn ystod y pum mlynedd diwethaf, mae'r bont wedi bod ar gau i gerbydau ochrau uchel ar gyfartaledd saith gwaith y flwyddyn.


Dywedodd llefarydd ar ran UK Highways A55:



> "Rydym wedi derbyn argymhelliad gan beirianwyr strwythurol i gau'r bont am resymau diogelwch. Rydym wedi trosglwyddo'r argymhelliad hwn i Lywodraeth Cymru ac yn gweithio'n agos â nhw i sicrhau bod diogelwch ac uniondeb Pont Menai yn cael eu cynnal.
> 
> 
> "Er y bydd y mater hwn yn amharu ar bobl, rhaid i ni weithredu er budd diogelwch y cyhoedd. Ar hyn o bryd rydym yn adolygu'r canfyddiadau a arweiniodd at yr argymhelliad i gau ac yn asesu'r holl opsiynau sydd ar gael i ailagor y bont cyn gynted â phosibl fel y gall pobl ddefnyddio’r bont yn rheolaidd unwaith eto.”


Dywedodd Lee Waters, y Dirprwy Weinidog Newid Hinsawdd, sy'n gyfrifol am drafnidiaeth:



> "Mae'r gwaith brys hwn yn cael ei wneud er mwyn diogelwch y cyhoedd. Nid oes modd ei osgoi yn anffodus, ond rydym yn gwbl ymwybodol o'r effaith y bydd yn ei gael ar bobl yn yr ardal leol.
> 
> 
> "Rydym yn gweithio'n agos ag UK Highways i sicrhau bod y gwaith hwn yn cael ei wneud yn ddiogel ac mor gyflym â phosibl gyda chyn lleied o darfu â phosibl ar y gymuned leol."

Structural engineers have recommended that Menai Bridge should close to all traffic to allow essential maintenance work to take place. This will take effect from 14:00hrs on Friday 21 October.


The announcement was made following recent testing of the bridges existing hangers. As part of UK Highways A55 ongoing maintenance of the Menai Bridge, it was identified that further testing would need to be carried out on the Menai Bridge alongside the replacement of some of the hangers.


As a result of further investigation, serious risks have been identified and structural engineers have recommended to close Menai Bridge to all traffic. The findings that led to the recommendation to close the bridge are currently being reviewed which could take up to two weeks. Available options to reopen the bridge as soon as possible are being actively assessed.


Temporary hanger strengthening works may need to be installed to ensure the safety and integrity of the Menai Bridge. This programme could take between 14 to 16 weeks, with the bridge reopening in early 2023\.


In the meantime, traffic will be diverted to the Britannia Bridge.


Following discussions with UK Highways and their structural experts, the footway across the bridge has been re\-opened for pedestrians and dismounted cyclists.


People must remain on the pedestrian footways and numbers will be limited. Marshalls will be in place from Friday, 21 October to Monday, 24 October to manage pedestrian flows and monitoring will be put in place to ensure compliance moving forward.


Plans have been discussed with partners including Welsh Government, UK Highways A55, NMWTRA, Emergency Services and the local authorities.


The Welsh Government is developing further strategies to increase resilience on the Britannia Bridge to mitigate the risk of both bridges being closed in exceptional circumstances. In the last five years, the bridge has been closed to high\-sided vehicles on average seven times a year.


A spokesperson for UK Highways A55 said



> “We have received a recommendation from structural engineers to close the bridge for safety reasons. We have passed on this recommendation to the Welsh Government and are working closely with them to ensure the safety and integrity of the Menai Bridge is maintained.
> 
> 
> “While this issue will cause disruption, we must act in the interest of public safety. We are currently peer reviewing the findings that led to the recommendation of closure and assessing all available options to reopen the bridge as soon as possible so people can get back to using the bridge regularly.”


Deputy Minister for Climate Change with responsibility for transport, Lee Waters said:



> “This urgent work is being carried out for public safety, unfortunately it is unavoidable, but we are fully aware of the implication this will have for people in the local area.
> 
> 
> “We are working closely with UK Highways to ensure this work is carried out safely and as quickly as possible with minimal disruption to the local community.”
