The local roads authority may, if in their opinion work in relation to a private road is necessary because circumstances constituting an emergency (other than an emergency constituted by such danger as is mentioned in section 91 of this Act) have arisen, carry out that work; and they shall not require to give any notice of their intention in that regard other than such (if any) as those circumstances appear to them to admit.

The expenses of carrying out work under subsection (1) above shall be borne by the authority.
