The new Dyfi bridge is one of the first projects to be completed after the Welsh Government’s response to the independent roads review that took place in February last year.
Y bont newydd dros afon Dyfi yw un o'r prosiectau cyntaf i'w gwblhau ar ôl ymateb Llywodraeth Cymru i'r adolygiad ffyrdd annibynnol a gynhaliwyd ym mis Chwefror y llynedd.
