(1)Where the Secretary of State gives a direction to the Director requiring him to implement any trunk road local plan, or Minister’s trunk road local plan, or part of any such plan, it shall be the duty of the Director to implement the provisions of the plan or (as the case may be) of that part of the plan, so far as they have effect in relation to any trunk road, as soon as is reasonably practicable.
(2)Any direction given under subsection (1) above may require any provision to which it applies to be implemented to such limited extent as may be specified in the direction.
(3)In so doing, the Director shall have all the powers which the Secretary of State would have in relation to any trunk road with respect to which the plan has effect, so far as may be necessary or expedient for the purpose of implementing the provisions of the plan.
(4)Anything done by the Director in purported exercise of those powers shall be taken to have been done by the Secretary of State.
(5)Where the Director considers that the implementation of any part of the plan requires a London authority to exercise any of its powers he may, in writing, ask the authority to exercise such powers as he may specify in his request.
(6)Where—
(a)the Director has sent such a request to a London authority; but
(b)the authority have not, in his opinion, exercised the powers in question within a reasonable period,
the Director may direct them to do so.
(7)Where a London authority have failed to comply with a direction under subsection (6) above within such period as the Director considers could reasonably be required by them, he may himself exercise the powers in question.
(8)Anything done by the Director in the exercise of those powers shall be treated for all purposes as if it had been done by the London authority.
(9)Where the Director proposes to exercise any of the powers of a London authority by virtue of subsection (7) above, he may direct that authority not to exercise those or any other such powers, in such circumstances or in relation to such matters, as may be specified in the direction.
(10)Where, having intervened under subsection (7) above, the Director is satisfied that continued intervention by him is unnecessary—
(a)he shall notify the London authority accordingly in writing; and
(b)with effect from the date on which that notice is served by him, any direction given by him with respect to his intervention shall cease to have effect.
(11)Any reasonable administrative expenses incurred by the Director in the exercise of his powers under subsection (7) above shall be recoverable by him from the London authority as a civil debt.
(12)Where the Secretary of State implements any of the provisions of a trunk road local plan, he shall have in relation to those provisions the powers conferred upon the Director by subsections (5) to (11) above.
