Roads may be discontinued for a number of reasons, including as as result of a road deviation. The hatched road in the image below is an example of a discontinued road.
A Council may, in addition to any power given to it by sections 43 and 44 of the Planning and Environment Act 1987-
(a) discontinue a road, or part of a road, by a notice published in the Government Gazette; and
(b) sell the land from that road (if it is not Crown land), transfer the land to the Crown or itself or retain the land.
