We have instructed the Environment Agency to work with Welsh Government transport officials and their North Wales Trunk Road Agent to consider the resilience of the A55.
Rydym wedi rhoi cyfarwyddyd i Asiantaeth yr Amgylchedd weithio gyda swyddogion trafnidiaeth Llywodraeth Cymru ac Asiant Cefnffyrdd Gogledd Cymru i asesu gwytnwch yr A55.
