Byddai’r gwaith hwn wedi’i wneud yn wreiddiol wedi seibiant yr haf. Ond mae’r ffaith bod lefelau traffig ar yr A55 bron hanner y lefel arferol oherwydd y pandemig coronafeirws, gan roi’r cyfle i gwblhau’r gwaith yn gynt na’r bwriad gyda llai o darfu ar y cyhoedd.
The work would originally have been carried out after the summer embargo. But traffic levels on the A55 are almost half their normal level as a result of the coronavirus pandemic, providing a window to complete the work earlier than intended with minimal disruption to the public.
