Abstract: Replacing New York State's Tappan Zee Bridge involved traversing more than just water; the team also crossed the hurdles of poor foundation conditions and the enormous scale of the crossing. Creative solutions included long-span plate-girder approaches, precast and preassembled components, giant waterborne cranes, and simultaneous fabrication paths that helped meet the project schedule.
