(1) Whenever, in terms of an operative master plan or local plan or an approved scheme, a road is declared to be closed or diverted—
(a) the local planning authority shall notify the Surveyor-General of the date on which the closure or diversion of the road became effective in terms of that plan or scheme and furnish such other information in regard thereto as the Surveyor-
General may require; and
(b) upon receipt of the notification in terms of paragraph (a), the Surveyor-General shall endorse the general plan of the land affected accordingly and sections 45, 46 and 47 of the Land Survey Act [Chapter 20:12] shall not apply in relation to the closure or diversion of that road.
(2) Where a road, the ownership of which is vested in the President or a road authority, is closed as a result of a closure or diversion in terms of an operative master plan or local plan or an approved scheme, the ownership of the land concerned shall, notwithstanding the closure of the road, continue to vest in the President or road authority, as the case may be.
