The Left Coast Lifter (West Coast Lifter), one of the world’s largest cranes, was custom built to rebuild a portion of the San Francisco-Oakland Bay Bridge. American Bridge/Fluor, the bridge contractors, arranged through a contract provision that they would be able to keep the massive floating crane free of charge after its use on the Bay Bridge project. It’s now reported that American Bridge/Fluor has leased the crane for an undisclosed amount to Tappan Zee Constructors, the private consortium building the Tappan Zee Replacement Bridge.
