Super Crane removes first section of Tappan Zee

Another moment in history: the super crane’s first lift in a year-long process of dismantling the Tappan Zee Bridge. One hundred thirty-three deck panels and two moveable barrier machines will be sent to nearly 12 state and local municipalities.

Twenty-nine months ago the giant crane lifted its first set of structural steel girders onto piers for the new bridge near the Rockland shoreline.

Below is a cross-section of the Tappan Zee Bridge’s Westchester approach span, a little like when someone cuts into a sheet cake and lifts out a precise piece.

Eight local munis and the New York State Department of Transportation (NYSDOT) asked for desk panels, valued at nearly $3 million including removal and delivery. Details here. Photos courtesy of New York State Thruway Authority.

Each of those panels — in use until last month —  is approximately 13 feet wide by 50 feet long, 8.25 inches thick and approximately between 75,500-86,500 pounds.

The moveable barrier system will head to the New York City Department of Transportation. To learn about the bridge that will slowly disappear, click here.

I’d like to know what you think.

    The demolition is almost as exciting as the construction…especially when you know quite a bit of the old bridge will be reused, recycled or repurposed. It is a great green story. Metal being recycled, deck panels being reused and giant chunks being used to create artificial reefs to provide habitat and safety to shorefront communities during hurricanes! Great work Thruway!
