Paragraph 16

The undertaker must not, without the consent of the relevant highway authority, construct any part of the works authorised by this Order under, or within 50 metres of, the surface of any highway which comprises a carriageway except in accordance with plans submitted to, and approved by, the relevant highway authority.

If within 28 days after such plans have been submitted the relevant highway authority has not approved or disapproved them, it is deemed to have approved the plans as submitted.

In the construction of any part of the said works under a highway no part of it may, except with the consent of the relevant highway authority, be so constructed as to interfere with the provision of proper means of drainage of the surface of the highway or be nearer than 2 metres to the surface of the highway.
