The adoption of the 1963 Constitution reorganized the department. No longer would the highway commissioner be elected. Instead, a six-member commission appointed by the governor and headed day to day by a department director initial appointed by the commission. The new commission would also have jurisdiction over "such other public works of the state as provided by law. At the time, the name was rearranged to the Michigan Department of State Highways. The legislative authorization led to 1970s reorganization of the department. An executive order by Governor William G. Milliken gave the department authority over all transportation programs in Michigan. The department was renamed on August 23, 1973, to the Michigan Department of State Highways and Transportation giving it responsibility for aviation, railroads, buses, ships, ports and non-motorized pathways and trails. The name was later shortened to the current form in 1978.
