Amhariad ar y T4 / Disruption on the T4

Oherwydd cau sawl safle bysiau yng nghanol Aberhonddu am ychydig wythnosau, bydd y T4 sydd yn dwad o Merthyr yn teithio trwy Heol Gouesnou ac wedyn mynd heibio Morrisons tuag at Free Street. Ymddiheurwn am unrhyw anghyfleustra
Due to the closure of several bus stops in the centre of Brecon for a few weeks ,the T4 will be travelling via Heol Gouesnou and passed Morrisons towards Free Street when travelling from Merthyr.
