Furcolo's administration was marked by the continuing trend of corruption in state government that had been growing in prior administrations. One notable series of cases involved the construction of the parking garage under the Boston Common. Furcolo established the Massachusetts Parking Commission to oversee the effort, but did not place it under any sort of oversight. The commission was self-financed by floating bonds, and a number of actors were later documented to extract more the $800,000 from the commission's construction funds by a variety of schemes. Four people were convicted and served prison time for these acts. A second major scandal, involving collusion between state public works officials, appraisers and landowners along planned interstate highway routes, took place in the 1950s. Details of the scams, described by politicians at that time as "the granddaddy" of highway-related malfeasance, were squelched by a Democratic-controlled Congressional investigation until after the 1960 election, apparently to avoid embarrassing Kennedy in his run for president. The scandal resulted in the conviction of several Massachusetts highway officials.
