CHICAGO – Officials at Chicago’s Willis Tower say the popular tourist attraction is safe, even though a glass ledge jutting from the building’s 103rd floor appeared to crack beneath the feet of a visiting family.
The see-through glass bays are known as The Ledge and extend about four feet from the building, which was once called the Sears Tower.
Officials said the family wasn’t in danger when the cracks appeared Wednesday on a glass enclosure.
In a statement Thursday, Willis Tower said a protective coating covering the glass surface cracked, not the glass itself. The cracks, it said, don’t affect the “structural integrity” of the ledge, which is designed to occasionally crack.
The ledges opened in 2009.
