"Nid yw'r rhan hon o'r A55 yn rhan hawdd i yrru arni yn sgil ei haliniad a graddiant ac mae'r bobl sy'n gyrru ar gyflymder sy'n peryglu bywydau pobl eraill, a'u bywydau eu hunain, yn anghyfrifol iawn. Hoffwn annog pawb i gadw golwg ar eu cyflymder teithio.
“This is not the easiest stretch of road to navigate due to its gradient and alignment and people travelling at speeds which put others, let alone themselves, in danger is simply irresponsible and I’d urge everyone to consider how fast they are going.
