MAE GWEINIDOGION CYMRU wedi gwneud Gorchymyn o dan adran 14 o Ddeddf Rheoleiddio Traffig Ffyrdd 1984, sy’n angenrheidiol oherwydd y tebygolrwydd o berygl i’r gweithlu a’r cyhoedd i ganiatáu ar gyfer cynnal gwaith hanfodol i archwilio a gosod arwyneb newydd ar gefnffordd yr A48 rhwng Cylchfan Sunnybank, Baglan, a Chylchfan Llansawel, Llansawel, Castell-nedd Port Talbot, neu gerllaw iddi.

Effaith y Gorchymyn dros dro fydd gwneud y canlynol dros dro:

i) Gwahardd pob cerbyd, ac eithrio’r rhai a ddefnyddir gan y gwasanaethau brys ac ar gyfer y gwaith, rhag mynd ar y darn o gefnffordd yr A48 a ddisgrifir yn yr Atodlen i’r Hysbysiad hwn. Disgrifir y llwybr arall yn yr Atodlen honno;

ii) Gwahardd pob beiciwr a phob cerddwr rhag mynd ar y darn o gefnffordd yr A48 a ddisgrifir yn yr Atodlen i’r Hysbysiad hwn;

iii) Gosod terfyn cyflymder o 50 a 40 mya ar y darn o gefnffordd yr A48 a ddisgrifir yn yr Atodlen i’r Hysbysiad hwn;

iv) Gosod terfyn cyflymder o 10 mya ar y darn o gefnffordd yr A48 a ddisgrifir yn yr Atodlen 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.

Daw’r Gorchymyn i rym ar 7 Medi 2026. Disgwylir y bydd y cyfyngiadau a’r gwaharddiadau dros dro, y codir arwyddion priodol yn eu cylch, yn weithredol dros nos o 20:00 o’r gloch ar 7 Medi 2026 hyd 06:00 o’r gloch ar 29 Medi 2026, neu hyd nes y caiff yr arwyddion traffig dros dro eu symud ymaith yn barhaol.

Dim ond yn ystod y nosweithiau ar y dyddiadau a bennir uchod y disgwylir i’r Gorchymyn arfaethedig 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 oherwydd amgylchiadau nad oedd modd eu rhag-weld.
