Er mwyn mynd i’r afael â’r gwaith rhwng cyffyrdd 24 a 28 mae rhaglen waith dros bedwar penwythnos ac wyth noson wedi'i rhoi ar waith sy'n cynnwys cau cerbytffordd yn llawn, gan osgoi cau'r gerbytffordd tua'r dwyrain a'r gerbytffordd tua’r gorllewin ar yr un pryd. Gallai hyn gael ei leihau i ddau benwythnos ac wyth noson gan ddibynnu ar y tywydd.
To accommodate works between junction 24-28 a four-weekend and eight-night work programme has been put in place involving full carriageway closures, avoiding simultaneous closure of the eastbound and westbound carriageway. This could be reduced to two weekends and eight nights depending on weather conditions.
