(1) The highway authorities of the state, counties, cities, and towns are authorized to design any controlled-access facility and to regulate, restrict, or prohibit access to best serve the traffic for which the facility is intended, and their determination of the design shall be final. In this connection, the highway authorities are authorized to divide and separate any controlled-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.
(2) No person shall have any right of ingress or egress to, from or across controlled-access facilities to or from abutting lands, except at designated points at which access may be permitted, upon terms and conditions that may be specified from time to time.
