Subject to subsection (2) below an order under section 14 or 18 above (orders for certain purposes connected with trunk, classified or special roads) and an order under section 248 of the Town and Country Planning Act 1990 (order by Minister or London Borough to stop up or divert highway that crosses etc. a main highway) may authorise the appropriate authority—
to stop up any private means of access to premises adjoining or adjacent to land comprised in the route of the relevant road, or forming the site of any works authorised by the order or by any previous order made under the same enactment;
to provide a new means of access to any such premises.
For the purposes of subsection (1) above—
the appropriate authority in the case of an order under section 248 of the Town and Country Planning Act 1990 is the highway authority for the main highway, and in any other case is the authority by whom the order is made; and
the relevant road is the trunk road, classified road, special road or, as the case may be, main highway to which the order relates.
No order authorising the stopping up of a means of access to premises shall be made or confirmed by the Minister by virtue of subsection (1)(a) above unless he is satisfied—
that no access to the premises is reasonably required, or
that another reasonably convenient means of access to the premises is available or will be provided in pursuance of an order made by virtue of subsection (1)(b) above or otherwise.
