Mae’r A48 tua’r dwyrain yn Sir Gaerfyrddin wedi’i chau ar hyn o bryd er mwyn i waith gael ei wneud ar biblinell sy’n cludo mathau gwahanol o danwydd o burfa Penfro.
The current closure of the A48 eastbound in Carmarthenshire is to allow works to take place on a multi-fuel pipeline from Pembroke refinery.
