Fodd bynnag, rwy’n cydnabod bod gwella llif y traffig yn bwysig iawn i lwyddiant economaidd De Cymru.  Felly, rwyf wedi gofyn i’m swyddogion gysylltu â Dinas-ranbarth Bae Abertawe i’w cael yn rhan o astudiaeth ehangach o goridor yr M4 o amgylch Abertawe sy’n cael ei ddatblygu ar hyn o bryd.
However, I recognise that improvement of strategic traffic flow is of great importance to economic prosperity in South Wales. Therefore, I have asked my officials to engage with Swansea Bay City Region to seek their involvement in a wider study of the M4 corridor around Swansea that is currently being developed.
