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.
