The Turnpike Authority also owned the Callahan Tunnel and the Sumner Tunnel, the other two road connections between downtown Boston and East Boston under Boston Harbor. Upon completion of the Central Artery/Tunnel Project, all tunnels constructed as part of the Big Dig, including the O'Neill Tunnel segment of I-93, were transferred to its control. The Authority received no state or federal government funding. Its revenues came from tolls, leases on air rights and service areas, and advertising. Its assets were all transferred to the new MassDOT agency as part of the restructuring of agencies.
