GORCHYMYN CEFNFFORDD YR A470 (CYLCHFAN GLANTWYMYN, POWYS I GYLCHFAN MALLWYD, GWYNEDD) (GWAHARDD CERBYDAU DROS DRO) 2025
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 A470, neu gerllaw iddi, rhwng Glantwymyn, Powys a Mallwyd, Gwynedd.
Effaith y Gorchymyn yw gwahardd dros dro bob cerbyd, ac eithrio’r rhai a ddefnyddir gan y gwasanaethau brys, ar gyfer y gwaith neu gerbydau gwasanaeth cynnal a chadw yn ystod y gaeaf, rhag mynd ar y darn o gefnffordd yr A470 sy’n ymestyn o ochr ogleddol Cylchfan Glantwymyn hyd at ochr ddeheuol Cylchfan Mallwyd.
Y llwybr arall ar gyfer cerbydau sy’n teithio tua’r gogledd fydd mynd ar yr A489 tua’r de-orllewin i Fachynlleth a’r A487 tua’r gogledd i Cross Foxes i ailymuno â’r A470 tua’r gogledd/de: i’r gwrthwyneb ar gyfer cerbydau sy’n teithio tua’r de.
Daw’r Gorchymyn i rym ar 1 Rhagfyr 2025. Disgwylir y bydd y gwaharddiad dros dro yn weithredol yn ysbeidiol rhwng 19:00 o’r gloch ar 1 Rhagfyr a 06:00 o’r gloch ar 15 Rhagfyr 2025, neu hyd nes y caiff yr arwyddion traffig dros dro eu symud ymaith yn barhaol.
Dim ond yn ystod y cyfnod 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 neu waith arall. Bydd hysbysiad am unrhyw newidiadau i’r amseroedd a’r dyddiadau yn cael ei arddangos cyn gwneud unrhyw waith a ailamserlennir.

THE A470 TRUNK ROAD (CEMMAES ROAD ROUNDABOUT, POWYS TO MALLWYD ROUNDABOUT, GWYNEDD) (TEMPORARY PROHIBITION OF VEHICLES) ORDER 2025
THE WELSH MINISTERS have made an Order under section 14 of the Road Traffic Regulation Act 1984, which is necessary to undertake works on or near the A470 trunk road between Cemmaes Road, Powys and Mallwyd, Gwynedd.
The effect of the Order is to temporarily prohibit all vehicles, other than those being used by the emergency services, for the works or winter maintenance service vehicles, from proceeding on the length of the A470 trunk road that extends from the northern side of Cemmaes Road Roundabout to the southern side of Mallwyd Roundabout.
The alternative route for northbound vehicles is via the south-westbound A489 to Machynlleth and northbound A487 to Cross Foxes to rejoin the north/southbound A470: vice versa for southbound vehicles.
The Order comes into force on 1 December 2025. The temporary prohibition is expected to operate intermittently from 19:00 hours on 1 December until 06:00 hours on 15 December 2025, or until the temporary traffic signs are permanently removed.
Although the Order is only expected to be in force during the period specified above, it will remain valid for a maximum period of 18 months, as a contingency, should the work need to be rescheduled or consequential or other work is required. Notice of any changes to times and dates will be displayed before any rescheduled work begins.
