In Part 3 of the 1991 Act, in relation to works which are major highway works by virtue of paragraph (1), references to the highway authority concerned are to be construed as references to the undertaker.

The following provisions of the 1991 Act do not apply in relation to any works executed under the powers conferred by this Order—

• section 5649 (power to give directions as to timing of street works);

• section 56A50 (power to give directions as to placing of apparatus);

• section 5851 (restriction on works following substantial road works);

• section 58A52 (restriction on works following substantial street works);

• section 73C55 (materials, workmanship and standard of re-surfacing);

• section 78A56 (contributions to costs of re-surfacing by undertaker); and

• Schedule 3A57 (restriction on works following substantial street works).

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 prohibition, restriction, regulation, alteration or diversion of a street of a temporary nature by the undertaker under the powers conferred by article 11 (temporary prohibition, restriction or regulation of use or alteration or diversion of streets) whether or not the prohibition, restriction, regulation, alteration or diversion constitutes street works within the meaning of that Act.

The provisions of the 1991 Act58 referred to in paragraph (4) are—

• section 5459 (advance notice of certain works), subject to paragraph (6);

and all such other provisions as apply for the purposes of the provisions mentioned above.

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 prohibition, restriction, regulation, alteration or diversion (as the case may be) required in a case of emergency.
