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.

Amhariad ar y gwasanaeth/Disruption to service T5

14th Sep 2026 onwards

Gwasanaeth T5 am y 10 wythnos nesaf. Bydd y B4333 ar gau y tu allan i Aberporth. Bydd bysus yn parhau i deithio i mewn i Aberporth ac yn gwasanaethu Parcllyn fel yn ôl yr amserlen bresennol. Bydd y bws yn teithio trwy Aberporth hyd at stop bws Sgwâr Aberporth, lle bydd yn troi'n ôl ac yn dychwelyd tuag at yr A487. Ni fyddwn yn gwasanaethu Parcllyn ar y ffordd yn ôl tuag at yr A487. Efallai y bydd y ddirywiad hwn yn arwain at rai oedi ychwanegol i'r gwasanaeth.
T5 service for the next 10 weeks.
The B4333 will be closed just outside Aberporth.
Buses will continue to travel into Aberporth and serve Parcllyn as per the current timetable. The bus will travel through Aberporth as far as the Aberporth Square bus stop, where it will turn around and return towards the A487.
However we will not serve Parcllyn on the route back towards the A487.
This diversion may result in some additional delays to the service.
