Y tro diwethaf y bu'n rhaid cau rhai lonydd oedd adeg cynnal y gwaith hanfodol ar gerbytffordd y gorllewin er mwyn atgyweirio Pont Kneeshaw Lupton yn Llanddulas. Cyn y gwaith yma roedd 532 diwrnod wedi mynd heibio ers i lonydd gael eu cau yn ystod y dydd ar yr A55 rhwng Cyffordd 11 a ffin Lloegr, sef yn ystod mis Ebrill 2017.
The last work which meant some lanes had to be closed was the essential work to the westbound carriageway of the Kneeshaw Lupton Bridge in Llanddulas. Before these works there had been 532 days since the previous routine daytime lane closures on the A55 between Junction 11 and the English border, dating back to April 2017.
