In addition to Government Center, Furcolo was also instrumental in the development of Boston's Prudential Center. The site of an unused railyard in the Back Bay had for some years been the subject of development proposals. Prudential Insurance sought limitations on Boston's tax assessments on the proposed development, and portions of the site were also being considered for use as an extension of the Massachusetts Turnpike. Furcolo helped to broker the deal, making it possible for Prudential to begin construction. The Supreme Judicial Court struck down aspects of the deal regarding the Metropolitan Transportation Authority (MTA, now the MBTA), leading to a work stoppage on the project in 1960.
