Article 5
The Secretaries of State direct as respects any part of a highway which crosses the route of any of the new trunk roads that—
where the highway is maintainable at the public expense by a local highway authority, the part in question shall be maintained by that authority, and
where the highway is not so maintainable and is not maintainable under a special enactment or by reason of tenure, enclosure or prescription, the Secretaries of State shall be under no duty to maintain the part in question,
until in either case, a date to be specified in a notice given to the highway authority for that highway by the Secretary of State for Transport, in respect of a highway in England, or the Secretary of State for Wales, in respect of a highway in Wales. The date specified will not be later than the date on which the relevant route is opened for traffic.
