Objections to a development in Offaly have also been withdrawn.
Plans for over 400 new homes in Athlone are being lodged directly with An Bord Pleanála.
The developer, Castlestar, is bypassing local planners because it's deemed a Strategic Housing Development and can therefore be fast-tracked.
If approved, the 237 houses and 189 apartments will be built in the Cornamagh, Clonbrusk and Coosan townlands.
The project will be known as Dún an Rí..
Meanwhile, objections to a new housing estate in Edenderry are being withdrawn.
The plans propose 90 homes adjacent to the existing Tyrell's Brook development on Fr. Paul Murphy Street.
