Gallai'r gwaith adeiladu ddechrau erbyn diwedd 2022 / dechrau 2023, yn amodol ar gwblhau'r broses statudol. Disgwylir i'r broses hon gynnwys ymchwiliad lleol cyhoeddus.
Construction could begin in late 2022/early 2023 subject to completing the statutory process, which is likely to include a public local inquiry.
