The five members of the MassDOT Board of Directors are appointed by the governor to staggered, four-year terms, within statutory requirements for experience, expertise and party affiliation. Two must be experts in public or private transportation finance; two must have practical experience in transportation planning; one must be a registered civil engineer with at least 10 years experience. The governor can remove any director for cause. The governor also appoints a secretary to a term that coincides with that of the governor, to serve as MassDOT's chief executive, administrative and operational officer. The governor has sole discretion to remove the secretary (Mass. Gen. Laws Ann. ch. 6C, §2).
