Regardless of the temporary prohibition or restriction of use of streets under the powers conferred by article ‎11 (temporary closure of streets and public rights of way), the undertaker must not prevent Northern Powergrid from taking 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.
