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 A40, neu gerllaw iddi, rhwng Sander, Sir Gaerfyrddin a Hwlffordd, Sir Benfro. Effaith y Gorchymyn yw gwneud y canlynol dros dro:

i. gosod terfyn cyflymder o 40mya neu 10mya ar y darnau o'r A40 a ddisgrifir yn Atodlen 1 i'r Hysbysiad hwn; a

ii. gosod terfyn cyflymder o 10mya ar y darnau o'r A40 a ddisgrifir yn Atodlen 2 i'r Hysbysiad hwn.

Dim ond pan fydd gwaith confoi yn digwydd y bydd y terfyn cyflymder o 10mya yn gymwys ac ni chaniateir goddiweddyd ar yr adegau hyn.

Daw'r Gorchymyn i rym ar 20 Awst 2026. Disgwylir y bydd y cyfyngiadau a'r gwaharddiad dros dro yn weithredol yn ysbeidiol o 00:01 o'r gloch ar y dyddiad hwnnw am gyfnod o 18 mis ar y mwyaf.
