The commissioner, in addition to specific powers granted in connection with controlled-access facilities, shall also have and may exercise, relative to such controlled-access facilities, any and all additional authority now or hereafter vested in him relative to highways or the state road system. He may also regulate, restrict, or prohibit the use of such controlled-access facilities by the various classes of vehicles or traffic in a manner consistent with section thirty- nine of this article.
