Yn anffodus, bu i’r ddau ddigwyddiad hwn ddigwydd yn fuan wedi’r oedi a gafodd gyrwyr ar y 3ydd Mehefin ar yr A55 ym Modelwyddan, oherwydd digwyddiad gyda person bregus ar bont.  Bu Heddlu Gogledd Cymru yn rheoli’r digwyddiad a bu rhywfaint o broblemau gyda trafodaethau rhwng Asiantaethau’r Gefnffordd a’r heddlu.  Mae’n anarferol i ddigwyddiad o’r fath barhau cyhyd.
Unfortunately these two incidents came shortly after the delays drivers experienced on 3 June on the A55 at Bodelwyddan, which were due to an incident involving a vulnerable person on a bridge. North Wales Police took the lead in managing the incident and there appear to have been some issues with liaison between the Trunk Road Agents and the police. It is unusual for such an incident to be as prolonged as this one was.
