(GWAHARDDIADAU A CHYFYNGIADAU TRAFFIG DROS DRO) 2025

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 A465, neu gerllaw iddi, rhwng Cylchfan Aberdulais a Chylchfan Resolfen, Castell-nedd Port Talbot.

Effaith y Gorchymyn yw gwneud y canlynol dros dro:

i) gwahardd pob cerbyd, ac eithrio’r rhai a ddefnyddir ar gyfer y gwaith, rhag mynd ar y darnau o gefnffordd yr A465 a ddisgrifir yn Atodlenni 1 a 2 i’r Hysbysiad hwn.

Disgrifir y llwybrau eraill, y codir arwyddion priodol yn eu cylch, yn Atodlen 1 i’r Hysbysiad hwn hefyd;

ii) gosod terfyn cyflymder o 40 mya ar y darnau o gefnffordd yr A465 a ddisgrifir yn Atodlen 1 i’r Hysbysiad hwn;

iii) gosod terfyn cyflymder o 10 mya ar y darnau o gefnffordd yr A465 a ddisgrifir yn Atodlen 1 i’r Hysbysiad hwn. Dim ond yn ystod gwaith confoi y bydd y terfyn cyflymder o 10 mya yn gymwys ac ni chaniateir goddiweddyd ar yr adegau hyn.

Disgwylir y bydd y gwaharddiadau a’r cyfyngiadau dros dro, y codir arwyddion priodol yn eu cylch, yn weithredol yn ysbeidiol o 20:00 o’r gloch ar 15 Awst 2025 ac yn parhau tan 06:00 o’r gloch ar 1 Rhagfyr 2025, neu hyd nes y caiff yr arwyddion traffig dros dro eu symud ymaith yn barhaol.

Dim ond yn ystod yr amseroedd a’r dyddiadau a bennir uchod y disgwylir i’r Gorchymyn fod yn weithredol. Er hynny, bydd yn parhau’n ddilys am gyfnod o 18 mis ar y mwyaf rhag ofn y bydd angen ailamserlennu’r gwaith neu wneud gwaith canlyniadol neu waith arall. Bydd hysbysiad ymlaen llaw am unrhyw newidiadau i’r amseroedd a’r dyddiadau yn cael ei arddangos cyn gwneud unrhyw waith a ailamserlennir.
