6(1)The provisions of this paragraph have effect in relation to, and in relation to the construction of, any new bridge, or any extension or alteration of an existing bridge, which carries—U.K.
(a)any part of the works authorised by this Act over a highway, or
(b)a highway over any part of those works.
Any such new bridge, or (as the case may be) any bridge so extended or altered, is referred to in this paragraph as “"the bridge””.
(2)Before commencing the construction of, or the carrying out of any work in connection with, the bridge which involves interference with a highway, the nominated undertaker must submit to the highway authority for its approval plans, drawings and particulars (in this paragraph referred to as “"plans””) relating to the work, and the bridge must not be constructed and the works must not be carried out except in accordance with the plans submitted to, and approved by, the highway authority.
(3)If, within 28 days after the plans have been submitted, the highway authority has not approved or disapproved them, it is to be deemed to have approved the plans as submitted.
(4)If the bridge carries any part of the works authorised by this Act over any highway—
(a)it must be constructed in such manner as to prevent so far as may be reasonably practicable the dripping of water from the bridge, and
(b)the highway authority may, at the cost of the nominated undertaker, provide and place such lamps and apparatus as may from time to time be reasonably necessary for efficiently lighting any highway under or in the vicinity of the bridge.
