Fe'i disgrifir fel cynllun sy'n gwrthsefyll yr hinsawdd gan nad oedd y Bont ar Ddyfi flaenorol o'r 19eg ganrif wedi'i chynllunio i gario'r traffig presennol ac roedd ar gau yn aml oherwydd llifogydd cyson.
It is described as a climate resilient scheme as the previous 19th century Pont-ar-Ddyfi bridge was not designed to carry the current volume of traffic and was often closed due to frequent flooding.
