Roedd nifer o leoliadau ble y bu'n amhosibl teithio ar y rhwydwaith, yn anffodus, ac roedd yn rhaid i'r ffyrdd gau.  Dyma'r peth olaf y mae rhywun am ei wneud, ac nid oedd unrhyw benderfyniad i gau ffyrdd yn cael ei wneud yn ysgafn.  Er i'n hymdrechion i ail-agor ffyrdd ac i achub pobl gael eu rhwystro i raddau mewn rhai lleoliadau oherwydd y cerbydau oedd wedi eu gadael ar ffyrdd, roedd pob un o'n rhwydweithiau ffyrdd wedi'u hail-agor erbyn dydd Sul.  Mae gwasanaethau bysiau ledled Cymru bellach yn ôl fel arfer, gyda rhai eithriadau lleol.  Mae ein timau hefyd wedi rhoi cymorth i awdurdodau lleol.
There were a number of locations where unfortunately our network became impassable and roads had to be shut. This is always a last resort, and any decisions to close roads were not taken lightly. Whilst reinstatement and rescue efforts were hampered in some locations by abandoned vehicles, all of our road network was re-opened by Sunday. Bus services across Wales are now operating normally, with some localised exceptions. Our teams have also been providing support to aid local authorities.
