The undertaker may enter upon and appropriate so much of the subsoil of, or air-space over, any street within the limits of deviation or the further limits as may be required for the purposes of or in connection with the authorised works and may use the subsoil and air-space for those purposes or any other purpose connected with or ancillary to the Sunderland extension.

The power under paragraph (1) above may be exercised in relation to a street without the undertaker being required to acquire any part of the street or any easement or right in the street.

The undertaker shall not be required to pay any compensation for the exercise of the powers conferred by paragraph (1) above where the street is a highway; but where the street is not a highway any person suffering loss by the exercise of that power shall be entitled to compensation to be determined, in case of dispute, under Part I of the Land Compensation Act 1961.
