GORCHYMYN CEFNFFORDD YR A470 (CILFAN I’R DE O GYLCHFAN
CYFARTHFA, MERTHYR TUDFUL) (GWAHARDD CERBYDAU DROS
DRO) 2025

MAE GWEINIDOGION CYMRU wedi gwneud Gorchymyn o dan adran 14 o Ddeddf
Rheoleiddio Traffig Ffyrdd 1984, sy’n ofynnol oherwydd y tebygolrwydd o berygl i’r
cyhoedd, neu o ddifrod difrifol i’r ffordd, na ellir eu priodoli i waith, ar gefnffordd yr
A470 i’r de o Gylchfan Cyfarthfa, Merthyr Tudful, neu gerllaw iddi.
Effaith y Gorchymyn yw gwahardd dros dro bob cerbyd, ac eithrio’r rhai sy’n cael eu
defnyddio gan y gwasanaethau brys neu gan gontractwr y cytunwyd arno wrth osod
neu gynnal a chadw cyfarpar priffyrdd, rhag mynd ar y darn o’r gilfan sy’n gyfagos i
gerbytffordd tua’r de y gefnffordd rhwng Cylchfan Cyfarthfa a Chylchfan Rhyd-y-car.
Daw’r Gorchymyn i rym ar 20 Hydref 2025. Disgwylir y bydd y gwaharddiad dros dro
yn weithredol o 00:01 o’r gloch ar 20 Hydref hyd 23:59 o’r gloch ar 2 Tachwedd 2025,
neu hyd nes y caiff yr arwyddion traffig dros dro eu symud ymaith yn barhaol.
Dim ond yn ystod y dyddiadau a bennir uchod y disgwylir i’r Gorchymyn fod yn
weithredol. Er hynny, bydd yn parhau’n ddilys am gyfnod o 6 mis ar y mwyaf.
