KVLY-TV mast

The KVLY-TV mast (formerly the KTHI-TV mast) is a 2,063 ft (628.8 m) tall television-transmitting mast in Blanchard, Traill County, North Dakota, United States, used by Fargo station KVLY-TV channel 11. Completed in 1963, it was the tallest structure ever built until succeeded by the Warsaw radio mast in 1974; that mast collapsed in 1991, making the KVLY-TV mast again the tallest structure in the world until the Burj Khalifa overtook it in 2010. It remains the third-tallest structure in the world (since the construction of the Tokyo Skytree), and the tallest structure in the western hemisphere. It is a guyed mast, not a self-supporting structure, and is therefore not included in lists of tallest buildings. The height of the transmitting antenna itself is 113 feet (34 m) and is included in the height of the tower as the lattice tower itself ends around 1,950 feet (590 m). The tower weighs 864,500 pounds (392.1 t) altogether and takes up 160 acres (0.65 km2) of land with its guy anchors. The 113-foot antenna alone weighs 9,000 pounds. In 1989, daredevils climbed the tower and BASE jumped from it.
