Bydd y gwaith yn dechrau ar 17 Mai, a disgwylir iddo bara am dair wythnos, yn dibynnu ar amodau tywydd – ond gwneir pob ymdrech i orffen y gwaith yn gynnar, os oes modd gwneud hynny.
The work is scheduled to begin on 17th of May and is programmed to last for three weeks, depending on weather conditions, but every effort will be made to finish ahead of schedule if that is possible.
