A 40mph speed limit is also being introduced on a separate length of the A458 to extend the existing 40mph limit and reduce the overall speed of traffic on the approaches to the school.
Cyflwynir terfyn cyflymder 40mya hefyd ar ddarn gwahanol o’r A458 i estyn y terfyn cyflymder 40mya presennol ac i ostwng cyflymder traffig yn gyffredinol ar y ffyrdd sy’n arwain at yr ysgol.
