SCARSDALE, N.Y. -- Eager fifth-grade students from Quaker Ridge School, armed with questions and binoculars, visited the new New York Bridge offices in Tarrytown to learn more about construction of the $4 billion bridge, which will replace the Tappan Zee Bridge in 2018, and to watch construction of the bridge from a viewing spot nearby.
The students, accompanied by teachers Mark Winston and Amy Kenney, listened as Dan Marcy of the New York State Department of Transportation, who does educational outreach programs on construction of the new bridge, explained to students that more than 5,000 people are working on the new bridge.
Marcy noted that more than 1,000 reinforced steel pilings, installed in the river bed, will help to hold the two-span bridge up when it is completed. Construction materials for the bridge have been transported to the site from places as far away as Washington State, said Marcy, and the bridge is being constructed to withstand a 2,500-year earthquake.
The I Lift NY super crane, which has helped to speed up the construction process, is a floating crane that will have made 134 lifts of heavy materials for the bridge work. Marcy also noted that three factories make concrete right at the bridge site. Students put their binoculars to work when they visited the New New York Bridge’s outdoor viewing stand, which is located at the Scenic Hudson RiverWalk Park in Tarrytown.
Winston noted that the bridge visit couldn’t be better timed – the fifth-graders were slated to begin work on their own engineering feats -- bridges made of popsicle sticks and glue.
