Fluor Team Wins $3.1-Billion Contract for Tappan Zee Bridge Replacement

The New York State Thruway Authority and the New York DOT selected Tappan Zee Constructors for the multi-billion dollar, design-build contract for the new Tappan Zee Hudson River Crossing Project. Fluor owns 30 percent of the joint venture, which also includes American Bridge Co., Granite Construction Northeast, and Traylor Bros.

The $3.14 billion contract will replace the 3.1-mile-long, 57-year-old Tappan Zee bridge.

"We will be able to leverage our recent successful bridge construction experiences, like the San Francisco-Oakland Bay Bridge, and our unique equipment capabilities in making this important project a reality," said Steve Dobbs, president of Fluor’s Industrial & Infrastructure Group.

The Tappan Zee connects Rockland County to Westchester County in the Lower Hudson Valley (approximately 25 miles north of midtown Manhattan) and is a vital transportation link that serves approximately 138,000 vehicles per day.

The mega-project will be the single largest bridge project in New York’s history. It is the state’s first application of its recently enacted design-build legislation and has produced substantial savings relative to the $5.2 billion estimated cost.

The Fluor team developed a unique design that reduced the weight of the structure and minimized the number and size of foundations required. The design solution also utilizes a shallow superstructure and a 350-ft.-long span design to minimize the number of piers and provide a sleeker looking bridge that enhances the view corridors within the lower Hudson Valley. The main span is a composite deck cable-stayed structural system with outwardly inclined main span towers that create an iconic look and accommodate future transit loads.

The design reduces dredge quantities from 1.8 million cubic yards to less than one million cubic yards, lightening environmental impacts, costs, and schedule durations. In addition, the construction schedule will benefit from utilizing unique heavy lifting equipment that Fluor and its partner American Bridge own and had custom built for the San Francisco-Oakland Bay Bridge project. Construction will take approximately five years with completion projected for 2018.
