GORCHYMYN CEFNFFORDD YR A465 (CASTELL-NEDD I LANDARCY, CASTELL-NEDD PORT TALBOT)
(GWAHARDDIADAU A CHYFYNGIADAU TRAFFIG DROS DRO) 2024

MAE GWEINIDOGION CYMRU wedi gwneud Gorchymyn o dan adrannau 14 a 15(2) o Ddeddf Rheoleiddio Traffig Ffyrdd 1984. Mae angen y Gorchymyn er mwyn gwneud gwaith ar gefnffordd yr A465 rhwng Castell-nedd a Llandarcy, neu gerllaw iddi.

Effaith y Gorchymyn yw gwneud y canlynol dros dro:

i. Gwahardd pob cerbyd rhag mynd ar y darnau o gefnffordd yr A465 a bennir yn Atodlen 1 i’r Hysbysiad hwn. Disgrifir y trefniadau ar gyfer y llwybrau eraill yn yr Atodlen honno hefyd.

ii. Cau naill ai’r gerbytffordd tua’r gorllewin neu’r gerbytffordd tua’r dwyrain a gwahardd goddiweddyd ar y darn o gefnffordd yr A465 a ddisgrifir yn Atodlen 2 i’r Hysbysiad hwn. Bydd gwrthlif yn gweithredu yn lôn allanol pa gerbytffordd bynnag a fydd yn aros ar agor i draffig.

iii. Gwahardd cerbydau dros 2.9 metr o led a phob cerbyd sy’n pwyso 44 tunnell neu fwy rhag mynd ar y darnau o gefnffordd yr A465 a bennir yn yr Atodlenni i’r Hysbysiad hwn. Disgrifir y llwybr arall yn Atodlen 1.

iv. Gwahardd beicwyr rhag mynd ar y darnau o gefnffordd yr A465 a bennir yn yr Atodlenni i’r Hysbysiad hwn.

v. Gosod terfyn cyflymder 30 mya, 40 mya neu 50 mya ar y darnau o gefnffordd yr A465 a bennir yn yr Atodlenni i’r Hysbysiad hwn.

Daw’r Gorchymyn i rym ar 1 Tachwedd 2024. Disgwylir y bydd y ffordd ar gau yn ystod y nos (20:00 – 06:00 o’r gloch) ond y bydd ar agor gyda gwrthlif yn ystod y dydd (06:00 – 20:00 o’r gloch). Disgwylir y bydd y gwaharddiadau a’r cyfyngiadau dros dro amrywiol yn weithredol yn ysbeidiol, a phan fydd arwyddion traffig yn dangos hynny, o 20:00 o’r gloch ar 1 Tachwedd 2024 nes y bydd y gwaith wedi ei gwblhau a hyd nes y caiff yr arwyddion traffig dros dro eu symud ymaith yn barhaol. Mae Gweinidogion Cymru wedi eu bodloni y bydd yn cymryd mwy na 18 mis i orffen y gwaith.
