Mae rhestr o ddatrysiadau posibl yn cael ei datblygu a'i hasesu, sy'n nodi coridor yr A483 rhwng Cyffyrdd 3 a 6, a'r cyffyrdd cysylltiedig, fel rhannau allweddol i'w gwella. Bydd rhagor o waith yn cael ei wneud ar y cynigion hyn.
A list of possible solutions is being developed and assessed, which identifies the A483 corridor between junction 3 and 6, and associated junctions, as key areas for improvement. Further work will be carried out on these proposals.
