4.—(1) Works executed under this Order in relation to a highway which consists of or includes a carriageway are to be treated for the purposes of Part 3 of the 1991 Act (street works in England and Wales) as major transport works if—
(a)they are of a description mentioned in any of paragraphs (a), (c) to (e), (g) and (h) of section 86(3) of that Act (which defines what highway authority works are major highway works); or
(b)they are works which, had they been executed by the highway authority, might have been carried out in exercise of the powers conferred by section 64 of the 1980 Act (dual carriageways and roundabouts) or section 184 of that Act (vehicle crossings).
(2) In Part 3 of the 1991 Act references, in relation to major highway works, to the highway authority concerned are, in relation to works which are major transport works by virtue of paragraph (1), to be construed as references to the undertaker.
(3) The following provisions of the 1991 Act do not apply in relation to any works executed under the powers of this Order—
section 56 (directions as to timing);
section 56A (power to give directions as to placing of apparatus);

section 73C (materials, workmanship and standard of re-surfacing);
section 78A (contributions to costs of re-surfacing by undertaker); and
Schedule 3A (restriction on works following substantial street works).
(4) The provisions of the 1991 Act mentioned in paragraph (5) (which, together with other provisions of that Act, apply in relation to the execution of street works) and any regulations made, or code of practice issued or approved under, those provisions apply (with the necessary modifications) in relation to any stopping up, alteration or diversion of a street of a temporary nature by the undertaker under the powers conferred by article 13 (temporary stopping up of streets) whether or not the stopping up, alteration or diversion constitutes street works within the meaning of that Act.
(5) The provisions of the 1991 Act referred to in paragraph (4) are—
section 54 (advance notice of certain works), subject to paragraph (6);
section 55 (notice of starting date of works), subject to paragraph (6);

and all such other provisions as apply for the purposes of the provisions mentioned above.
(6) Sections 54 and 55 of the 1991 Act as applied by paragraph (4) have effect as if references in section 57 of that Act to emergency works were a reference to a stopping up, alteration or diversion (as the case may be) required in a case of emergency.
(7) Nothing in article 15 (maintenance of altered or diverted streets)—
(a)affects the operation of section 87 of the 1991 Act (prospectively maintainable highways), and the undertaker is not by reason of any duty under that article to maintain a street to be taken to be the street authority in relation to that street for the purposes of Part 3 of that Act; or
(b)has effect in relation to street works as respects which the provisions of Part 3 of the 1991 Act apply.
(8) To such extent as is reasonably necessary for protecting the authorised transit system and its operation and use the undertaker has the same powers as respects reinstatement as a street authority has under section 72 of the 1991 Act.
(9) In its application to the authorised transit system section 93(3) of the 1991 Act also permits the undertaker to make reasonable requirements—
(a)for allowing it facilities to monitor the execution of the works; and
(b)for the protection of the authorised transit system.
