Bydd yr astudiaeth yn cael ei hariannu drwy gam dylunio a datblygu’r drydedd bont, gwerth £3m, sy’n rhan o’r gyllideb ddwy flynedd y cytunwyd arni gan Lywodraeth Cymru a Phlaid Cymru.
The feasibility study agreement will be funded through the £3m design and development stage of the third crossing which is part of the two-year budget agreed by the Welsh Government and Plaid Cymru.
