“Yn gyntaf oll, rydym wedi cynnal rhaglen waith ar raddfa fawr dros y 4 blynedd diwethaf er mwyn sicrhau bod twnelau’r A55 yng Nghonwy, Penmaenbach a Phen y Clip yn bodloni’r safonau cyfreithiol a’r safonau dylunio diweddaraf. Rwy’n falch iawn o nodi’r ffaith y daeth y rhaglen i ben neithiwr, a bod twnel Conwy bellach ar agor yn unol â’r arfer. Rwyf bellach yn disgwyl i’r holl waith cynnal a chadw a’r holl waith gwella yn y tymor canol a’r hirdymor gael ei gynnal dros nos.
“Firstly, over the last 4 years we have undertaken a major programme of works to bring the A55 tunnels at Conwy, Penmaenbach and Pen y Clip up to current legislative and design standards. I am pleased to report that the programme came to an end last night with the re-opening to normal operation of the Conwy tunnel.  It is now my expectation that all maintenance and improvement works for the medium to long term will be carried out overnight.
