MAE GWEINIDOGION CYMRU wedi gwneud Gorchymyn o dan adran 14 o Ddeddf Rheoleiddio Traffig Ffyrdd 1984. Mae angen y Gorchymyn er mwyn gwneud gwaith ar gefnffordd yr A458, neu gerllaw iddi, rhwng ffin Powys/Swydd Amwythig, man i’r dwyrain o Dreberfedd, a ffin Powys/Gwynedd yn Nant-y-dugoed, Powys.
Effaith y Gorchymyn yw gosod terfyn cyflymder dros dro o 40 mya, 30 mya neu 10 mya ar y darn o’r A458 o ffin Powys/Swydd Amwythig, man i’r dwyrain o Dreberfedd, hyd at ffin Powys/Gwynedd yn Nant-y-dugoed.
