A465 Trunk road (Glanbaidend roundabout to Hardwick Interchange Abergavenny) - Temporary restrictions for carriageway maintenance

GORCHYMYN CEFNFFORDD YR A465 (CYLCHFAN GLANBAIDEN I
GYFNEWIDFA HARDWICK, Y FENNI) (GWAHARDD CERBYDAU
DROS DRO) 2026
MAE GWEINIDOGION CYMRU wedi gwneud Gorchymyn o dan adran 14 o Ddeddf Rheoleiddio Traffig Ffyrdd 1984. Mae angen y Gorchymyn oherwydd y tebygolrwydd o berygl i’r cyhoedd oherwydd gwaith a wneir i adnewyddu cymal pont a gwaith cynnal a chadw arferol ar gerbytffordd cefnffordd yr A465 rhwng Cylchfan Glanbaiden a Chyfnewidfa Hardwick, neu gerllaw iddi.
Effaith y Gorchymyn arfaethedig fydd gwahardd dros dro bob cerbyd, ac eithrio’r rhai a ddefnyddir gan y gwasanaethau brys ac ar gyfer y gwaith, rhag mynd ar y darnau o’r A465 a ddisgrifir yn yr Atodlen i’r Hysbysiad hwn. Disgrifir y trefniadau ar gyfer llwybrau eraill hefyd yn yr Atodlen i’r Hysbysiad hwn.
Daw’r Gorchymyn i rym ar 15 Mehefin 2026. Disgwylir y bydd y gwaharddiad dros dro yn weithredol dros nos o 20:00 o’r gloch ac yn parhau tan 06:00 o’r gloch ar 17 Mehefin 2026, 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.

PROHIBITION OF VEHICLES) ORDER 2026
THE WELSH MINISTERS have made an Order under section 14 of the Road Traffic Regulation Act 1984, which is necessary due to the likelihood of danger to the public because of bridge joint renewal and routine carriageway maintenance works being undertaken on or near the A465 trunk road between Glanbaiden Roundabout and Hardwick Interchange.
The effect of the proposed Order will be to temporarily prohibit all vehicles, other than those being used by the emergency services and for the works, from proceeding on the lengths of the A465 described in the Schedule to this Notice.
The alternative route arrangements are also described in the Schedule to this Notice. The Order comes into force on 15 June 2026. The temporary prohibition is expected to operate overnight from 20:00 hours and remain until 06:00 hours on 17 June 2026, or until the temporary traffic signs are permanently removed.
Although the Order is only expected to operate 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 work is required. Notice of any changes to times and dates will be displayed before any rescheduled work begins.
