Subject to subsections (2) and (3) below, where, as regards navigable waters over which there is a swing bridge carrying a road, the Secretary of State is of the opinion that the number of ships using those waters and requiring the bridge to be opened has so declined over a period of years that the bridge ought no longer to be so operated, or ought to be so operated only in special circumstances, he may by order amend or repeal accordingly any enactment providing for such operation.

Parts I and III of Schedule 1 to this Act shall have effect in connection with the making of an order under this section; and Schedule 2 to this Act shall have effect in connection with the validity and date of operation of any such order.

If the objection to an order under this section is duly made in accordance with Schedule 1 to this Act by a navigation authority on whom notice is required to be served under paragraph 3 of that Schedule and that objection is not withdrawn the order shall be subject to special parliamentary procedure, and Part IV of that Schedule shall have effect for the purposes of the application to the order of the M1 Statutory Orders (Special Procedure) Act 1945.
