Where the boundary line of a county of this state is partially bounded by a stream or river which is one of the boundaries of this state and likewise one of the boundaries of an adjoining state, such county may, by resolution of its board of freeholders, resolve that a bridge or tunnel across such waters is a public necessity. The board of freeholders may authorize the making of preliminary examinations, surveys, drawings and soundings and the securing of preliminary estimates as to the cost of constructing a bridge or tunnel and approaches thereto, and may appropriate moneys to provide for such work to an amount not exceeding ten thousand dollars.
