Y FENNI, I FFIN CYMRU/LLOEGR, SIR FYNWY) (GWAHARDDIADAU A CHYFYNGIADAU TRAFFIG DROS DRO) 2026
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 Hardwick, y Fenni, a ffin Cymru/Lloegr.
Effaith y Gorchymyn yw gwneud y canlynol dros dro:
(1) 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 A465 a ddisgrifir yn yr Atodlen i’r Hysbysiad hwn. Disgrifir y trefniadau ar gyfer llwybrau eraill yn yr Atodlen honno hefyd;
(2) gwahardd pob beiciwr a phob cerddwr rhag mynd ar y darn o gefnffordd yr A465 a ddisgrifir yn yr Atodlen i’r Hysbysiad hwn;
(3) gosod terfynau cyflymder 50 mya a 40 mya ar y darn o gefnffordd yr A465 a ddisgrifir yn yr Atodlen i’r Hysbysiad hwn;
(4) gosod terfyn cyflymder 10 mya ar y darn o gefnffordd yr A465 a ddisgrifir yn yr Atodlen i’r Hysbysiad hwn. Dim ond yn ystod gwaith confoi y bydd y terfyn cyflymder 10 mya yn gymwys ac ni chaniateir goddiweddyd ar yr adegau hyn. Daw’r Gorchymyn i rym ar 16 Medi 2026. Disgwylir y bydd y gwaharddiad dros dro, y codir arwyddion priodol yn ei gylch, yn weithredol dros nos o 20:00 o’r gloch ar 16 Medi 2026 hyd 06:00 o’r gloch ar 30 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 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.
