The agency may design any limited access facility and regulate, restrict, or prohibit access as to best serve the traffic for which the facility is intended. In this connection, it may divide and separate any limited access facility into separate roadways by the construction of raised curbings, central dividing sections or other physical separations, or by designating the separate roadways by signs, markers, stripes, and other devices. No person may pass to, from, or across limited access facilities from or to abutting lands, except at such designated points as the agency may permit, and upon such terms and conditions as it may specify.
