No local authority shall erect or maintain any stop sign or traffic control signal at any location so as to require the traffic on any state highway to stop before entering or crossing any intersecting highway unless approval in writing has first been obtained from the department of transportation. For the purpose of this paragraph (i), striping, lane-marking, and channelization are considered traffic control devices.(j) Rights-of-way for such street shall be acquired by either the city, city and county, or incorporated town or by the state as is mutually agreed upon. Costs of acquiring such rights-of-way may be at the sole expense of the state or the city, city and county, or incorporated town, or both, as may be mutually agreed. Title to all rights-of-way so acquired shall vest in the city, city and county, or incorporated town, or the state, according to the agreement under which said rights-of-way were secured.(k) The department of transportation is authorized to acquire rights-of-way by purchase, gift, or condemnation for any such streets, highways, and bridges. Any such condemnation proceeding shall be exercised in the manner provided by law for condemnation proceedings to acquire lands required for state highways. Nothing in this section shall be construed as abrogating the rights of home rule cities to acquire lands for state purposes in the manner set forth in the charter of said cities.L. 53: p. 526, § 35.
