It was in the midst of these many legal problems that in April 1960 Prudential announced that continuation of their building project was contingent on direct highway access via a toll road along the Boston & Albany Rail Road right of way. Additionally, Prudential would lease air rights to the parcels from the Turnpike Authority and purchase a large portion of bonds issued by the Authority. Despite this agreement, Governor Volpe was still trying to nix the Turnpike's plans along the Boston and Albany right of way, filing the city of Newton's request with the ICC to stop the construction of the roadway. It was only after a series of meetings between Volpe, Callahan and Prudential executives that the Governor was finally persuaded to withdraw the ICC filing and reluctantly support the toll road. With the new deal in place, a not-guilty finding in the criminal case, and public relations push-back to the allegations of market tampering by the Turnpike Authority, the bond measures were once again seen as a sound investment and investors quickly picked up the $175 million (US$1.4 billion in 2014, adjusted for inflation) bond issuance. With the Turnpike-Prudential agreement in place, Logue was able to petition the General Court to once again authorize a land taking deal and tax-deferment bill, which was passed rather quickly and signed by then-Governor Foster Furcolo. While this new bill was again deemed unconstitutional by the SJC, in its decision the Court provided a framework for the legislature to construct a bill that would pass constitutional muster. The bill also gave Logue's BRA considerable powers over the redevelopment project, allowing him to rapidly move forward with permit approvals and tax issues. The Turnpike-Prudential deal linked with the Logue and the BRA's new powers to move the project forward quickly quieted much of the remaining opposition to the new roadway, and cemented the idea of air right development as an integral part of the Turnpike moving forward. By 1965 the Massachusetts Turnpike had been connected to the Central Artery, and the Prudential Center was on its way to completion; however, Callahan did not live to see this. On April 24, 1964, he died of a massive heart attack at his home.
