Oedi / Delay T4

Today 10:56 - 24th Jul 2026

Oherwydd bod Arddangosfa Frenhinol Cymru yn digwydd dros y 4 diwrnod nesaf, mae'n debyg y bydd oedi ar y T4 oherwydd traffig trwm yn ardal Builth Wells.
Due to the Royal Welsh Show taking place over the next 4 days there are delays to be expected to the T4 as a result of heavy traffic in the Builth Wells area.

Amhariad ar y T4 / Disruption on the T4

2nd Jul 2026 onwards

Ni fydd yr T4 yn gallu gwasanaethu Free Street, Aberhonddu tan hysbysiad pellach (oherwydd gwaith ffordd sy'n gwneud hi'n amhosibl i gerbydau fawr basio drwyddi). Dylai teithwyr fynd i'r Orsaf Bws yn Aberhanddu.
The T4 will not be able to serve Free Street, Brecon until further notice (due to roadworks making it impossible for larger vehicles to pass through).
Passengers should make their way to the Bus Interchange.

O'r 20fed o Gorffenaf hyd at 27ain Gorffenaf , mae gennym system unffordd ar Stryd Fawr Llanelwy. Bydd gwasanaethau T51 o Ryhl i Ddinbych yn gweithredu fel arfer. Gwasanaethau T51 o Ddinbych i Ryhll bydd yn troi trwy'r B5381 heol isaf Dinbych ac yn ailddechrau'r llwybr ar heol Glasgoed. Y stop olaf cyn y ffordd arall fydd goleuadau Trefnant. Bydd unrhyw wasanaethau sydd wedi'u dyddio i fynd trwy ganolfan Siopa Tweedmill yn dal i wneud hynny.
Starting j20th July until 27th July we have a 1 way system in operation on St Asaph high street. T51 services from Rhyl to Denbigh will operate as normal.
T51 services from Denbigh to Rhyl will divert via the B5381 lower Denbigh road And resume route on Glascoed road. The last stop prior to diversion will be Trefnant lights.

O ganlyniad i waith Scottish Power, ni ellir darparu gwasanaeth T51 i Llandegla i'r ddau gyfeiriad. Mae amser cwblhau'r gwaith yn anhysbys ar hyn o bryd
