Stone Monoliths To Be Installed on 9/11 Memorial Glade This Weekend
Stone Monoliths To Be Installed on 9/11 Memorial Glade This Weekend
Saturday, April 6, marks a significant milestone in the 9/11 Memorial Glade’s construction when the pathway’s six stone monoliths will be installed. These central design elements symbolize the strength and determination of those who are sick or who have died from 9/11-related illnesses caused by exposure to toxins in the aftermath of the 9/11 attacks. The Glade will also recognize rescue, recovery and relief workers who acted with courage, selflessness and perseverance.
The process of installing the monoliths requires a 600-ton crane and an assist crane. Each monolith, weighing between 13 and 17.8 tons, will be lifted over the existing 30 - 35 foot oak trees on the Memorial plaza before being rigged onto the Glade construction site. The southern two monoliths will be placed first, then the middle two and then the northern two last.
A newly constructed foundation of high-density Styrofoam, concrete and steel rebar will support the weight of the monoliths. This reinforcement is essential because the monoliths positioned on the Glade sit above the 9/11 Memorial Museum, which extends 70 feet underground.
For visitors coming to the site on Saturday, please know that until 2 p.m., the south and west sides of the 9/11 Memorial’s South Pool will be temporarily inaccessible because of surrounding construction.
