Ongoing deterioration has already caused breaches, such as in 2021 when part of the north promenade failed. ‌Construction of Barmouth’s causeway in the 1970s seeded new dunes, which are now growing exponentially as sand is blown south from north Barmouth beach.

This is to be replaced by an "unsightly" concrete wall ranging in height from 1.55 to 1.7 metres.
