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

It is a guyed mast, not a self-supporting structure, and is therefore not included in lists of tallest buildings.
Location
The tower is located 3 miles (4.8 km) west of Blanchard, North Dakota, halfway between Fargo and Grand Forks. It became the tallest artificial structure, and the first man-made structure to exceed 2,000 feet (610 m) in height, upon the completion of its construction on August 13, 1963.
