(GWAHARDD CERBYDAU, BEICWYR A CHERDDWYR DROS DRO) 2023
MAE GWEINIDOGION CYMRU wedi gwneud Gorchymyn o dan adran 14 o Ddeddf Rheoleiddio

Effaith y Gorchymyn yw gwahardd dros dro bob cerbyd (ac eithrio’r rhai a ddefnyddir gan y
gwasanaethau brys ac ar gyfer y gwaith), beiciwr a cherddwr rhag mynd ar y darn o’r A465 a

Ionawr ac yn weithredol yn ysbeidiol dros nos (20:00 o’r gloch – 06:00 o’r gloch) am gyfnod o 18 mis
