Paragraph 28 I1

Regardless of the temporary stopping up of streets and public rights of way under the powers conferred by article 13 (temporary stopping up of streets and public rights of way), a utility undertaker is at liberty at all times to take all necessary access across any such street and to execute and do all such works and things in, upon or under any such street as may be reasonably necessary or desirable to enable it to maintain any apparatus which at the time of the prohibition or restriction was in that street.
