KVLY-TV Mast, Blanchard, Traill County, North Dakota, United States

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 in the world 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 fourth-tallest structure in the world (since the construction of the Tokyo Skytree and the Shanghai Tower), the tallest structure in the western hemisphere, and the tallest radio mast in the world.
It is a guyed mast, not a self-supporting structure, and is therefore not included in lists of tallest buildings.
