GORCHYMYN CEFNFFORDD YR A470 (LLANFAIR-YM-MUALLT I LANGURIG, POWYS) (CYFYNGIADAU CYFLYMDER A DIM GODDIWEDDYD DROS DRO) 202-
MAE GWEINIDOGION CYMRU yn bwriadu gwneud Gorchymyn o dan adran 14 o Ddeddf Rheoleiddio Traffig Ffyrdd 1984 ymhen dim llai na 7 niwrnod i ddyddiad yr Hysbysiad hwn. Mae angen y Gorchymyn er mwyn gwneud gwaith ar gefnffordd yr A470, neu gerllaw iddi, rhwng Llanfair-ym-Muallt a Llangurig, Powys.
Effaith y Gorchymyn arfaethedig fydd gosod terfyn cyflymder dros dro o 40 mya, 30 mya neu 10 mya ar y darn o gefnffordd yr A470 rhwng ei chyffordd gylchfan â’r A483 yn Llanfair-ym-Muallt a’i chyffordd gylchfan â’r A44 yn Llangurig. Dim ond yn ystod gwaith confoi y bydd y terfyn cyflymder o 10 mya yn weithredol a ni chaniateir goddiweddyd ar yr adegau hynny.
Daw’r Gorchymyn i rym ar 11 Gorffennaf 2026. Disgwylir y bydd y cyfyngiadau a’r gwaharddiad dros dro, y bydd eu hyd a’u lled yn amrywio, yn weithredol yn ysbeidiol o 08:00 o’r gloch ar y dyddiad hwnnw am gyfnod hwyaf o 18 mis. Bydd hysbysiad am y gwaith yn cael ei arddangos cyn i unrhyw waith ddechrau.
